Embodiment 1

[0033] Such as Figure 1-7 As shown, the present invention provides a cooling device for an air conditioner controller, which includes:

[0034] controller 1;

[0035] The heat-absorbing module 3 can absorb heat and cool down the controller 1;

[0036] The heat absorption module 3 includes a heat exchange pipeline 31, the heat exchange pipeline 31 includes an inlet pipe 31a and an outlet pipe 31b, and the inlet pipe 31a communicates with the low-pressure refrigerant pipeline in the refrigerant circulation system of the air conditioner (from which the low-pressure low-temperature refrigerant is sucked in), and the outlet pipe 31b communicates with the suction port of the compressor 4 in the refrigerant circulation system of the air conditioner (the refrigerant after absorbing heat is sent to the suction port of the compressor).

[0037] By connecting the inlet pipe of the heat exchange pipeline in the heat absorption module with the low-pressure refrigerant pipeline in the re...

Embodiment 2

[0044] Such as figure 1 , preferably, it also includes an enclosure 2 capable of covering the controller 1 and the heat absorption module 3, and the heat absorption module 3 is located at the first inner wall position of the enclosure 2, and the controller 1 is located at The second inner wall of the closure cover 2 is located, and the first inner wall is opposite to the second inner wall.

[0045]By setting the structure of the closed cover outside the controller and the heat-absorbing module, a fully-sealed structure can be formed for the controller and the heat-absorbing module, effectively preventing damage to the controller by external factors such as dust, water, and insects, and ensuring Shield electromagnetic interference to a certain extent to ensure the safety and reliability of the controller.

Embodiment 3

[0047] Such as Figure 4-7 , preferably, the refrigerant circulation system of the air conditioner includes the compressor 4 , the condenser 5 , the evaporator 6 and the throttling device 7 . This is the main structural form of the refrigerant circulation system of the air conditioner of the present invention, which can complete the circulation of the refrigerant and realize the functions and effects of cooling and heating.

[0048] Option One

[0049] Such as Figure 4 , preferably, the inlet pipe 31a communicates with the refrigerant pipeline between the throttling device 7 and the evaporator 6 (from which low-pressure and low-temperature refrigerant is sucked in). This is the first scheme of the present invention to realize the connecting pipeline connection mode of the heat absorbing module, which can suck low-pressure and low-temperature refrigerant from between the throttling device and the evaporator in the circulation loop to achieve the effect of absorbing heat and ...

Abstract

The invention provides a heat dissipating device of an air conditioner controller and an air conditioner. The heat dissipating device of the air conditioner controller comprises a controller (1) and aheat absorbing module (3) which can perform heat-absorbing and cooling on the controller (1), wherein the heat absorbing module (3) comprises a heat exchange pipeline (31); the heat exchange pipeline(31) comprises an inlet tube (31a) and an outlet tube (31b); the inlet tube (31a) communicates with a low-pressure refrigerant pipeline in a refrigerant circulating system of the air conditioner; andthe outlet tube (31b) communicates with a gas absorbing hole of a compressor (4) in the refrigerant circulating system of the air conditioner. The heat dissipating device can suck in a low-pressure low-temperature refrigerant from the low-pressure refrigerant pipeline of the refrigerant circulating system, introduces the low-pressure low-temperature refrigerant into the heat absorbing module to perform heat-absorbing and cooling on the controller, and flows back into the gas absorbing hole of the compressor through the outlet tube, so that heat dissipating efficiency of the air conditioner controller is effectively improved, normal and safe work of the controller is guaranteed, the air conditioner can reliably operate under a high-temperature environment, and environment temperature rangefor air conditioner operation is increased.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a cooling device for an air conditioner controller and an air conditioner. Background technique [0002] In recent years, with the development of air-conditioning technology, air-conditioning has continuously broken through the cooling and heating technology in extreme environments. Among them, when cooling at high temperature, it is necessary to reduce the temperature of the power components in the operation of the air conditioner, so that the air conditioner can operate reliably. However, this type of radiator needs to increase the heat dissipation by increasing the area of ​​the shovel teeth, and the space of the external unit of the air conditioner is limited, and the larger the area, the greater the temperature difference between the tooth top and the tooth root, so its efficiency is also low. lower. Therefore, it is necessary to use a high-efficiency ...
