Heat energy exchange device capable of saving energy of water heater

Abstract

The invention relates to a heat energy exchange device capable of saving energy of a water heater. The device comprises an upper cover, a heat exchange plate module, a heat exchange tube module and abase, the top surface of the upper cover is provided with a water inlet, the bottom surface close to the base is provided with a water outlet, the heat exchange plate module is arranged below the water inlet of the upper cover and connected with the heat exchange tube module to form a closed communication water path, and is placed inside the base together, shower hot water flowing in through the water inlet of the upper cover firstly touches the heat exchange plate module, so that normal-temperature water preheated by the heat exchange tube module in the shower hot water can be guided to a water inlet of the water heater immediately after obtaining the heat exchange of highest-temperature heat energy, and therefore the energy consumption of the water heater can be greatly saved.

Description

technical field [0001] The present invention relates to a heat exchange device that can greatly save the energy of a shower water heater. Through the combination of a heat exchange plate module and a heat exchange tube module, the waste heat recovery rate of shower hot water can reach 60%. In turn, the energy consumption required for heating the water heater is saved, and the environmental protection and economic benefits of reducing energy consumption and carbon emissions are simultaneously achieved. Background technique [0002] In order to achieve the goal of energy saving and carbon reduction, many heat exchangers for household showers are currently on the market. The design principle is to guide tap water at normal temperature into the heat exchanger, and use the hot water after showering as the heat exchanger.

[0002] In order to achieve the goal of energy saving and carbon reduction, many heat exchangers for household showers are currently on the market. The design principle is to guide tap water at normal temperature into the heat exchanger, and use the hot water after showering as the heat exchanger. Heat source, so that the normal temperature tap water flowing through the heat exchanger can be preheated into higher temperature tap water, and then guide it to the water inlet pipe of the water heater. The inventor of this case has devoted himself to the research and development of the heat energy exchange device for shower hot water for more than 10 years, and has put forward the research and development results of the Chinese patent application for the record: authorized announcement number CN100552361 (application date January 17, 2006), Publication number CN101511242 (application date September 11, 2007), authorization announcement number CN201364044 (application date February 25, 2009), authorization announcement number CN201364045 (application date March 4, 2009), authorization announcement number CN102478367 (application November 24, 2010) and application publication number CN105403075 (application date September 11, 2014), etc., the aforementioned patents can achieve their intended functions after the inventor implements them. There is still room for improvement in saving the energy consumption of water heaters. The reason is that the above-mentioned heat exchange devices cannot improve the "waste heat recovery rate" of hot water after showering. The "waste heat recovery rate" of the water can increase the inlet water temperature of the water heater. When the inlet water temperature of the water heater is increased, the amount of energy (that is, the gas consumption or electricity consumption) required to heat the water to the desired outlet temperature can be reduced. , and then achieve the energy-saving effect of the water heater. Therefore, how to successfully transform the heat exchange device to further increase the "waste heat recovery rate" of shower hot water is extremely important.

[0003] In addition, when transforming the design structure of the heat exchange device to increase the "waste heat recovery rate", it must also take into account that its manufacturing cost cannot increase accordingly, otherwise, even though the "waste heat recovery rate" has increased, the manufacturing cost of the heat energy device will increase. , but it is not conducive to the promotion and sales to consumers, and at the same time, it cannot achieve the environmental protection and economic results of reducing energy consumption and carbon emissions after being used by every household.
