Problems solved by technology

This method is limited by the space of the unit, and the effect is not obvious, and the temperature drop is small
[0007] 3. Add a radiator to dissipate heat from the electronic control module. This method requires an additional radiator, which increases the cost and the complexity of the electronic control module.
The temperature drop is obvious, but there will be condensed water, which does not meet the national electrical safety standards

Abstract

The invention provides a cooling structure of an electric control module and an air conditioner outdoor unit, and relates to the technical field of air conditioners. The cooling structure of the electric control module comprises an electric control module body and a channel isolation plate, the channel isolation plate is used for being arranged in a shell and opposite to an air conditioner draughtfan, the channel isolation plate is provided with the draught fan side close to the air conditioner draught fan and an electrical side away from the air conditioner draught fan, the electric controlmodule body is arranged on the electrical side of the channel isolation plate, an induced air open hole is formed in the channel isolation plate, and penetrates the draught fan side and the electricalside, the induced air open hole is opposite to the electric control module body, and an induced air channel is formed between the air conditioner draught fan and the electric control module body. Compared with the prior art, the cooling structure of the electric control module is obvious in cooling effect, low in cost and capable of meeting the national electrical safety standard, meanwhile, design is simplified, and redundant components are not added.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat dissipation structure of an electric control module and an air conditioner external unit. Background technique [0002] The electronic control module in the air conditioner often generates a lot of heat during the working process. If the heat is not dissipated in time, it will affect the components in the electronic control module. [0003] For the inverter air conditioner external unit, on the one hand, many inverter module components are very sensitive to the upper temperature limit, and the effective life will be greatly reduced after the temperature limit is exceeded, and some even fail directly. On the other hand, there are many heating elements such as IGBT and IPM, and a large amount of heat accumulation in the electronic control module. Excessive temperature rise is very common in the development and use of inverter air conditioners, and heat dissipation ...
