Description
- 1. Field of the Invention
- The present invention relates generally to a water heater, and more particularly to a water heater module equipped with a detachable heat exchanger in order to improve heat transfer efficiency.
- 2. Description of the Related Art
-
FIG. 1 shows a conventional water heater including aburning chamber 1, apipe assembly 2 above theburning chamber 1, and aheat exchanger 3 between aninlet 2 a and anoutlet 2 b of thepipe assembly 2. It may heat cold water in thepipe assembly 2 with high temperature gas in theburning chamber 1 and the heated water flows out of thepipe assembly 2 via theoutlet 2 b. Such water heater is very common. However, its heat transfer efficiency is only between 72% and 83%. It is because that some thermal will escape along with the gas from the water heater rather than be transferred into water. - In order to improve heat transfer efficiency, some water heaters are equipped with secondary pipe assembly and heat exchanger therein that there are two sets of pipe assemblies and heat exchangers for pre-heating and heating that may improve the heat transfer efficiency. However, such water heater still has some problems:
- 1. Both sets of pipe assemblies and heat exchangers are mounted in the water heater that such water heater usually has a greater size. It is inconvenient for delivery and assembling.
- 2. Besides, both sets of pipe assemblies and heat exchangers are undetectable that there are two types of water heaters, which are single set of pipe assembly and heat exchanger and double sets of pipe assemblies and heat exchangers in the market for consumers to choose. Although the double sets type water heater has better heat transfer efficiency, its massive size is inconvenient for consumers.
- 3. There are carbon dioxide and vapor in the high temperature gas. It causes the formation of acid water which adhere to surfaces of the pipe assemble. Moreover, most part of the pipe assemble is received in the water heater while the burning chamber is also received in the water heater that it is hard to wash the pipe assemble. Consequentially, acid water will eventually rust pipe assemble in the long run.
- 4. When the high temperature gas heats the pipe assemblies in sequence, it will decrease the heat transfer efficiency because the high temperature gas is gathered in the same space.
- The primary objective of the present invention is to provide a water heater module, in which a heat exchanger can be detachably mounted in any type of water heater. The water heater of the present invention has a higher compatibility and better heat transfer efficiency when the secondary heat exchanger is mounted.
- The secondary objective of the present invention is to provide a water heater module equipped with a detachable heat exchanger, whose pipe is easy to wash and consequently reduces the rust problem.
- According to the objectives of the present invention, a water heater module of the present invention includes a water heater and an extra heat exchanger. The extra heat exchanger has a spiral pipe and is detachably connected to the water heater. The pipe is heated by high temperature gas from the water heater to pre-heat cold water in the pipe, and then the water is sent to the water heater for further heating.
- In order to improve the heat transfer efficiency, the present invention further provides a first fin assembly having a plurality of fins and a second fin assembly also having a plurality of fins, wherein the first fin assembly is received in the water heater, and the second fin assembly is received in the extra heat exchanger. Furthermore, the first fin assembly has an exhaust cross section area, which is smaller than an exhaust cross section area of the second fin assembly.

FIG. 2 andFIG. 3 , awater heater module 100 of the first preferred embodiment of the present invention includes awater heater 10 and anextra heat exchanger 20. In the present embodiment, thewater heater 10 is the same as the conventional water heater including afirst case 12, in which aburning chamber 14, afirst pipe 16 and afirst fin assembly 18 are provided. Theburning chamber 14 may generate high temperature gas to heat thefirst pipe 16. Thefirst pipe 16 has a first connectingend 16 a and anoutlet 16 b. Thecase 12 is provided with afirst opening 121 at a top thereof. Thefirst fin assembly 18 includes a plurality offins 181 arranged in a predetermined pattern. Intervals between thefins 181 are defined as S1. Thefirst pipe 16 extends through thefins 181. - The
extra heat exchanger 20 includes asecond case 22 having a plurality ofdetachable fasteners 23 to secure thefirst case 12 of thewater heater 10. Thesecond case 22 includes abottom plate 24 having asecond opening 241 communicated with thefirst opening 121 of thefirst case 12. In other words, the high temperature gas generated by theburning chamber 14 of thewater heater 10 flows into thesecond case 22 through thefirst opening 121 and thesecond opening 241 in sequence. - The
extra heat exchanger 20 further includes asecond pipe 26 and asecond fin assembly 28, as shown inFIG. 4 andFIG. 5 . Thesecond pipe 26 is a spiral pipe formed with a plurality ofannular sections 261 from top down. Thesecond pipe 26 has aninlet 26 a and a connectingend 26 b. Cold water flows into thesecond pipe 26 via theinlet 26 a, and the connectingend 26 b of thesecond pipe 26 is connected to the connectingend 16 a of thefirst pipe 16 of thewater heater 10. Thebottom plate 24 of thesecond case 22 is provided with acollecting slot 242 with a curved bottom beside thesecond opening 241 and aweephole 243 on the bottom of thecollecting slot 242. Thesecond case 22 further has adetachable panel 25. Thesecond fin assembly 28 has a plurality offins 281, and thesecond pipe 26 extends through thefins 281. Intervals between thefins 281 are defined as S2. - Above is the structure of the
water heater module 100 of the first preferred embodiment of the present invention. In practice, thefirst case 12 is filled with the high temperature gas generated by theburning chamber 14 of thewater heater 10, and thesecond case 22 is filled with the high temperature gas also to pre-heat water in thesecond pipe 26 that the water flows into thefirst pipe 16 from thesecond pipe 26 is warm. At the same time, the burningchamber 14 will also heat up the water in thefirst pipe 16 directly that the temperature of the water in thefirst pipe 16 will be raised within a short time. - The
first fin assembly 18 has an exhaust cross section area which is smaller than that of thesecond fin assembly 28. The exhaust cross section area is the total cross section area of the high temperature gas generated by the burningchamber 14 of thewater heater 10 passing through the fin assembly. Such structure will generate a stack effect with heat convection in thewater heater 10 and theextra heat exchanger 20. It may help the high temperature gas going up to improve the heat transfer efficiency. - Choosing a suitable number of
fins fins 181 of the first fin assemble 18 (shown inFIG. 3 ) is greater than thefins 281 of the second fin assemble 28 (shown inFIG. 5 ) that the intervals S1 of thefins 181 of the first fin assemble 18 is smaller than the intervals S2 of thefins 281 of the second fin assemble 28. Such pattern may generate aforesaid stack effect also. Besides the number of the fins, thickness of the fins may affect the stack effect also. For example, when the numbers of thefins fins 181 of the first fin assemble 18 are thicker, it may cause the exhaust cross section area of thefirst fin assembly 18 to become smaller than thesecond fin assembly 28. - The characters and advantages of the present invention are:
- 1. The
extra heat exchanger 20 is an independent item which has a high compatibility to be incorporated with any type of water heater. It may improve the heat transfer efficiency, and furthermore, consumers don't need to buy water heater with double pipes of other types to combine their water heater with the extra heat exchanger. - 2. Acid water on the
second pipe 26 will drop into the collectingslot 242 on thebottom plate 24 of thesecond case 22 and flows out through theweephole 243. It may reduce the rust problem of thesecond case 22 and thesecond pipe 26. - 3. When the
panel 25 of thesecond case 22 is disassembled, thesecond pipe 26 is exposed for washing and the burningchamber 14 will not interfere with washing. - 4. A predetermined design of the first and second fin assembles 18 and 28 may achieve the stack effect. It may improve the heat transfer efficiency and reduce the production of waste gas for safety.
- The water heater and the extra heat exchanger of the water heater of the present invention may be adjusted in its assembling way to become applicable to a different work place.
