Heat radiation structure of electronic control module and heat radiation method thereof, air conditioning outdoor unit and air conditioner

Abstract

The invention provides a heat radiation structure of an electronic control module, a heat radiation method for the electronic control module, an air conditioning outdoor unit and an air conditioner. The heat radiation structure of the electronic control module comprises the electronic control module, a detecting element, a collector, a water delivery pipe and a valve. The electronic control module is provided with a radiator. The detecting element is in electric connection with the electronic control module and used for detecting the temperature of the radiator and transmitting the detected temperature of the radiator to the electronic control module. The collector is in electric connection with the electronic control module and used for collecting and storing rainwater. A water inlet of the water delivery pipe is in communication with the collector, and a water outlet of the water delivery pipe is toward the radiator. The valve is in electric connection with the electronic control module, installed on the water delivery pipe, and used for controlling the water delivery pipe to open or close. According to the technical solution, when air cooling can not meet the heat radiation requirement of the radiator, the electronic control module can control the rainwater in the collector to be guided to the radiator through the water delivery pipe and cool the radiator, then burnout of an electronic control element on the electronic control module due to over temperature is avoided, and therefore the normal operation of the air conditioner is ensured.

Description

technical field [0001] The invention relates to the field of air-conditioning and refrigeration, and more specifically, relates to an electric control module heat dissipation structure, an electric control module heat dissipation method, an air conditioner outdoor unit and an air conditioner. Background technique [0002] Because inverter air conditioners have the advantages of energy saving and quietness, inverter air conditioners are gradually replacing fixed frequency air conditioners. But at present, with the continuous popularization of high-power inverter air conditioners, the heat generated by the electrical components on the electric control board of inverter air conditioners is also increasing. Among them, especially high-power devices such as electronic control modules, they will A large amount of heat is emitted and the temperature rises rapidly. If the heat is not dissipated in time, their performance will be reduced or even burned. Therefore, it is necessary to ...

Problems solved by technology

However, in the case of high-temperature and heavy-load cooling of the inverter air conditioner, because the air temperature in the case is usually high, the cooling effect of the radiator is greatly reduced.
