Description

Thermal energy exchange device capable of saving water source energy

The present invention relates to a heat energy exchange device capable of greatly saving energy of a shower water heater, which combines a heat exchange plate module and a heat exchange tube module to make the residual heat recovery rate of the shower hot water reach 60%. Save energy consumption required for heating water heaters, and simultaneously achieve environmental and economic benefits of reducing carbon emissions from energy consumption.

In order to achieve the goal of energy saving and carbon reduction, many heat exchangers for home showers have been put on the market. The design principle is to direct the tap water at normal temperature into the heat exchanger and use the hot water after the shower as a heat exchanger. The heat source enables the normal temperature tap water flowing through the heat exchanger to be preheated into a tap water of a higher temperature, and then is diverted to the water inlet pipe of the water heater, thereby increasing the temperature of the water inlet of the water heater, thereby saving the heating of the water heater. The energy of this case, and the creator of this case has been committed to the development of thermal energy exchange devices for shower hot water for more than 10 years, and the results of the research and development of the Chinese patent application are: authorized notice number CN100552361 (application date January 17, 2006), Publication No. CN101511242 (application date September 11, 2007), authorization notice number CN201364044 (application date February 25, 2009), authorization notice number CN201364045 (application date March 4, 2009), authorization notice number CN102478367 (application On November 24, 2010, and the application publication number CN105403075 (application date: September 11, 2014), the above-mentioned patents can achieve their pre-existing functions after being specifically implemented by the creators. Is its lack of reaction in the energy-saving water heaters In terms of usage, there is still room for further improvement. The reason is that the above-mentioned heat exchange devices are not able to improve the residual heat recovery rate of the hot water after showering, in other words, if the heat recovery of the hot water after showering can be improved When the rate is high, the water inlet temperature of the water heater can be increased. When the water inlet temperature of the water heater is increased, the amount of energy required to heat the desired outlet water temperature (ie, gas consumption or power consumption) can be reduced, thereby achieving the water heater. The energy-saving effect of using energy, therefore, how to successfully transform the heat exchange device to further improve the residual heat recovery rate of the shower hot water is extremely important.

In addition, in the design of the heat exchange device that increases the residual heat recovery rate, it must also take into account that the cost of its manufacturing cannot be increased. Otherwise, even if the heat recovery rate is increased, the manufacturing cost of the thermal device increases. However, it is not conducive to promoting sales to consumers, and at the same time it is unable to achieve the environmental economic results of reducing the carbon consumption of energy consumption after the use of households.

The function gradually increases, and because the axial surface of the stainless steel tube is wavy, in addition to speeding up the heat exchange, when the normal temperature water gradually heated by the first heat exchange enters the accommodation chamber of the heat exchange plate module, Moreover, since the top surface of the heat exchange plate module is located just below the water inlet of the upper cover, the temperature of the shower hot water flowing into the water inlet is at the highest temperature, so that the heat exchange plate module is accommodated in the room. Once again, the normal temperature water that has been preheated for the first time can be obtained again. The heat exchange of the highest temperature heat energy, and once again raises the temperature into the final preheated warm water, and then flows into the water inlet pipe of the water heater by the outlet pipe, thereby increasing the water inlet temperature of the water heater, and also reducing the heating of the water heater to The amount of energy required for the temperature of the water to be discharged (ie, the amount of gas used or the amount of electricity used is reduced), and relatively the efficiency of the water heater to save energy.

The normal temperature water W1 in the tube 41 is gradually heated by the first heat exchange of the shower hot water W. Since the axial surface of the stainless steel tube 41 is wavy, the speed of heat exchange is accelerated (as shown in Fig. 13). The temperature of the normal temperature water W1 which is gradually heated by the first heat exchange is entered into the accommodating chamber 34 of the heat exchange plate module 30, and the top surface 31 of the heat exchange plate module 30 is located at the upper cover 10 Below the water inlet 14, the temperature of the shower hot water W that has just flowed in from the water inlet 14 is at the highest temperature, so that the heat storage plate module 30 has been preheated for the first time in the accommodation chamber 34. The normal temperature water W1 can obtain the heat exchange effect of the highest temperature thermal energy again, and once again raises the temperature into the final preheated warm water W2, and then flows into the water inlet pipe P1 of the water heater 2 from the outlet pipe 37, thereby improving the water heater. 2 inlet water temperature, but also to reduce the heating of the water heater 2 to its desired water The amount of energy required (i.e., reduce the amount of electricity or gas consumption), and the opposite effect is attained food save the amount of energy used.
