Description

Technical Field

[0001] The present application relates to the field of air energy heat pumps, and more specifically, to a graphene evaporator and an air energy heat pump. Background Art

[0002] Air source heat pump uses the heat in the air to generate thermal energy. It can provide the whole family with different hot water, cooling and heating needs with large water volume, high water pressure and constant temperature 24 hours a day, while meeting the above requirements with the least energy consumption.

[0003] The air energy heat pump mainly includes four major components: evaporator, condenser, compressor, and expansion valve, which constitute a closed system. The evaporation of the evaporator is a physical process of converting liquid into gas. Generally speaking, the evaporator is an object that converts liquid substances into gas. The evaporator is a very important component among the four major refrigeration components. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, gasify and absorb heat, and achieve the cooling effect. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.

[0004] When the air energy heat pump is used in cold areas, when the ambient temperature is low and the air contains a certain amount of humidity, the evaporator is prone to frost, which will seriously affect the performance of the air energy heat pump and even cause it to shut down. Utility Model Content

[0008] In a specific embodiment, a cavity is formed inside each of the extended heat-conducting plates, and each cavity is communicated with the cavity.

[0009] In a specific implementation manner, a clamping fixture is disposed on the top of the mounting plate, and the clamping fixture clamps and fixes the bottom of the heat storage plate.

[0010] In a specific embodiment, the clamping fixture includes a U-shaped frame, and the opposite surfaces of the two side walls of the U-shaped frame are connected to clamping springs, and the clamping springs on both sides are connected to clamping plates, and the two clamping plates clamp the bottom of the heat storage plate.

[0015] The graphene evaporator described above.

[0016] Beneficial effects:

[0017] 1. Through the setting of the electric heater box heat storage plate, the temperature around the graphene evaporator can be automatically heated up to prevent the graphene evaporator from frosting and ensure the normal operation of the air energy heat pump.

[0026] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1-Figure 5 , the present application provides a graphene evaporator, including a graphene evaporator 1.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a heat storage plate 2 is arranged on the side of the graphene evaporator 1, a cavity 21 is opened inside the heat storage plate 2, an electric heater 5 is installed inside the cavity 21, an extended heat conduction plate 4 is equidistantly arranged on the side of the heat storage plate 2 close to the graphene evaporator 1, and a mounting plate 3 is detachably arranged at the bottom of the heat storage plate 2. Each extended heat conduction plate 4 is not in contact with the graphene evaporator 1. Among them, when the graphene evaporator 1 is frosted due to the ambient temperature during use, the electric heater 5 is started to increase the temperature of the heat storage plate 2, and then the heat is brought close to the side of the graphene evaporator 1 through the extended heat conduction plate 4, so that the surrounding temperature of the graphene evaporator 1 becomes higher, thereby preventing the graphene evaporator 1 from frosting. Through the arrangement of the electric heater 5 and the heat storage plate 2, the surrounding temperature of the graphene evaporator 1 can be automatically heated up to prevent the graphene evaporator 1 from frosting, thereby ensuring the normal operation of the air energy heat pump. Through the arrangement of the extended heat conduction plate 4, the distance between the heat and the graphene evaporator 1 is shortened, reducing the probability of frosting.

[0029] In this embodiment, each extended heat conducting plate 4 has a cavity inside, and each cavity is connected to the cavity 21. The cavity is connected to the cavity 21, so that heat is gathered inside the cavity, so that the temperature transfer effect is better.

[0030] In this embodiment, a clamping fixture 6 is provided on the top of the mounting plate 3, and the clamping fixture 6 clamps and fixes the bottom of the heat storage plate 2. The clamping fixture 6 includes a U-shaped frame 61, and the opposite surfaces of the two side walls of the U-shaped frame 61 are connected to clamping springs 62, and the clamping springs 62 on both sides are connected to clamping plates 63, and the two clamping plates 63 clamp the bottom of the heat storage plate 2. The tops of the two clamping plates 63 are fixedly connected with arc-shaped guide plates 64. Specifically, the arc-shaped guide plates 64 make it more convenient to install the heat storage plate 2 and have a guiding effect. A threaded hole is provided on the mounting plate 3, and the mounting plate 3 is connected to the lower wall of the shell. Among them, the bottom of the heat storage plate 2 is placed on the clamping plate 63, and the installation of the heat storage plate 2 is realized under the action of the clamping spring 62, and this method can facilitate the disassembly and installation of the heat storage plate 2 and facilitate subsequent maintenance.

[0031] See also Figure 1-Figure 5 The present application also provides an air energy heat pump, comprising:

[0032] The graphene evaporator mentioned above. Among them, the air energy heat pump uses the heat in the air to generate heat energy, which can provide the whole family with different hot water, cooling and heating needs with large water volume, high water pressure and constant temperature 24 hours a day, while consuming the least energy to meet the above requirements. The air energy heat pump is installed inside the shell, and the shell can protect the air energy heat pump unit.

[0033] Working principle of the graphene evaporator and air energy heat pump:

[0034] When the graphene evaporator 1 is frosted due to the ambient temperature during use, the electric heater 5 is started to increase the temperature of the heat storage plate 2, and then the heat is brought close to the side of the graphene evaporator 1 by extending the heat conduction plate 4, so that the temperature around the graphene evaporator 1 becomes higher, thereby preventing the graphene evaporator 1 from frosting. By setting the electric heater 5 and the heat storage plate 2, the temperature around the graphene evaporator 1 can be automatically raised to prevent the graphene evaporator 1 from frosting, thereby ensuring the normal operation of the air energy heat pump. By setting the extended heat conduction plate 4, the distance between the heat and the graphene evaporator 1 is shortened, reducing the probability of frosting.

[0035] It should be noted that the specific model and specifications of the electric heater 5 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
