Detailed Description
The utility model will be further described with reference to the following examples.
As can be seen from fig. 1 to fig. 2, the electric control heat dissipation structure in this embodiment includes a fan cavity 1 and a chassis cavity 2; an electric control box 3 is arranged in the case cavity 2; the case cavity 2 is communicated with the fan cavity 1 through the electric control box 3; the electric control box 3 is communicated with the case cavity 2; the electric control box 3 is communicated with the fan cavity 1;
an air inlet side 11 is arranged on one side of the fan cavity 1; an air outlet side 12 is arranged on the other side of the fan cavity 1; the fan cavity 1 is provided with a fan 4 between an air inlet side 11 and an air outlet side 12.
Specifically, in the electric control heat dissipation structure described in this embodiment, when the fan 4 in the fan cavity 1 is turned on, the fan cavity 1 is negative pressure, and the electric control box 3 is positive pressure, airflow flow between the electric control box 3 and the fan cavity 1 occurs; after the air in the electric control box 3 flows to the fan cavity 1, the air in the case cavity 2 is supplemented through the holes, and at the moment, an air flow structure of the case cavity 2, the electric control box 3 and the fan cavity 1 is formed, so that heat dissipation can be carried out on electric elements in the electric control box 3, condensation cannot be generated when the electric control box 3 and the case cavity 2 belong to a hot cavity, and meanwhile, compared with the mode that a radiating fin, a radiating plate and a radiating fan are added to the electric control box 3 in the prior art, the electric control box is simpler in structure and lower in cost, and associated problems cannot be caused by new addition of devices; in addition, the heat dissipation scheme of the refrigerating system pipeline arrangement difficulty (liquid cooling pipe) is not increased, and the heat dissipation effect and the cost reduction are considered.
In the electric control heat dissipation structure of the embodiment, the electric control box 3 is provided with a first through hole 31 communicated with the chassis cavity 2; the electric control box 3 is provided with a second through hole 32 communicated with the fan cavity 1. Specifically, through the trompil setting, can realize the intercommunication of automatically controlled box 3 and quick-witted case cavity 2 to and the intercommunication of automatically controlled box 3 and fan cavity 1, convenient and reliable.
In the electronic control heat dissipation structure of this embodiment, the fan cavity 1 is disposed at the bottom of the chassis cavity 2. In the electronic control heat dissipation structure of this embodiment, the first through hole 31 is disposed at the top of the electronic control box 3; the second through hole 32 is arranged at the bottom of the electric control box 3.
Specifically, through the above arrangement, the air flows as shown in fig. 1 and 2, and the first through hole 31 and the second through hole 32 are respectively arranged at the top and the bottom of the electric control box 3, so that the air flows through the electric control box 3 from top to bottom, and heat dissipation can be effectively performed on the electrical components of the electric control box 3.
In the electrically controlled heat dissipation structure of this embodiment, the area of the first through hole 31 is smaller than the area of the second through hole 32. The air flow tissue flow rate of the electric control box 3-the fan cavity 1 is determined by the negative pressure of the fan cavity 1 and the communication area of the negative pressure, and the negative pressure of the fan cavity 1 is determined by the rotating speed of the fan 4. When the negative pressure of the fan cavity 1 is constant, the larger the communication area between the fan cavity 1 and the electric control box 3 is, the larger the airflow flow formed by the negative pressure is; when the communication area is fixed, the higher the rotation speed of the fan 4 is, the larger the negative pressure is, and the larger the airflow rate is.
The airflow organization flow of the case cavity 2-the electric control box 3 and the airflow organization flow of the electric control box 3-the fan cavity 1 are balanced. Therefore, the communication area of the chassis cavity 2 and the electric control box 3 is smaller than that of the electric control box 3 and the fan cavity 1, so that the airflow velocity at the communication position of the chassis cavity 2 and the electric control box 3 can be increased, and corresponding communication positions are provided with electric control devices with large heating values such as variable frequency drive and the like, so that the heat dissipation of the devices with large heating values is more beneficial.

In the electric control heat dissipation structure according to this embodiment, a heat exchanger 5 is disposed between the fan 4 and the air inlet side 11 in the fan cavity 1.
In addition, the higher the heat load of the environment is, the higher the compressor frequency is, the higher the temperature of the controller (variable frequency drive) is, the higher the heating value is, and the higher the heat of the electric control box 3 is. The rotation speed of the fan 4 is in a direct proportion relation with the temperature of the controller, and the higher the temperature of the controller is, the corresponding increase of the rotation speed of the fan 4 is also achieved. At this time, the refrigerating capacity of the air conditioner is correspondingly improved, so that the environmental load is reduced, the frequency of the compressor is reduced, the heating value of the controller is reduced, and finally the rotating speed of the fan 4 is reduced, so that the environmental load, the refrigerating capacity, the rotating speed of the fan, the temperature of the controller and the heat dissipation of the electric control box 3 are balanced; therefore, the embodiment can utilize the self-adaptive electric control box 3 of the rotation speed of the fan 4 to generate heat and refrigerate the load, so as to form the balance of the refrigeration system.
An air conditioner comprises a compressor and an electric control heat dissipation structure; the compressor is arranged in the case cavity 2.
