Embodiment 1

[0107] Example 1, such as Figure 1-3 As shown, preferably,

[0108] The plurality of heat dissipation fins 2 are arranged radially diverging from the middle toward the outside, and form the cavity 20 for accommodating the fan assembly 1 in the middle. This is the preferred structural form of Embodiment 1 of the present invention, that is, a plurality of cooling fins are arranged in a radial arrangement form from the middle to the surroundings, and the heat can be radially radiated outward through the fins; the fan assembly is arranged on In the center of the fins, compared with the way of blowing air from the fan assembly behind or in front of the fins, the air can pass through all the fins more fully, and the airflow flows through every surface of the fins, further effectively increasing the The heat exchange area between the surface of the fin and the air is increased, and the heat exchange effect of the fin is improved.

Embodiment 2

[0109] Example 2, such as Figure 4-5 As shown, preferably,

[0110] The heat dissipation fins 2 are plate-shaped structures, and a plurality of the heat dissipation fins 2 are multi-layer board structures stacked, and each of the heat dissipation fins 2 is provided with a hole in the middle. The holes are stacked to form the cavity 20 for accommodating the fan assembly 1 . This is the preferred structural form of Embodiment 2 of the present invention, that is, a plurality of cooling fins are arranged in a stacked arrangement, and heat can be exchanged and transferred out between adjacent layers through the fins in a stacked form; The fan assembly is arranged in the center of the fins, compared with the way of blowing from the fan assembly behind or in front of the fins, the air can pass through all the fins more fully, and the airflow flows through every surface of the fins. The heat exchange area between the surface of the fin and the air is further effectively increased, ...

specific Embodiment approach

[0129] In the present invention, the control of the fan assembly of the radiator is linked with the air-conditioning system, and is divided into a fan operation mode or a non-operation mode, and the specific implementation methods are as follows:

Abstract

The invention provides a controller heat dissipation assembly, a control method and an air conditioner. The controller heat dissipation assembly comprises a heat dissipation substrate, a plurality ofheat dissipation fins and a fan assembly, one side of the heat dissipation substrate is attached to a heating component, the other side of the heat dissipation substrate is provided with the pluralityof heat dissipation fins, a cavity is formed in the heat dissipation fins, the fan assembly is arranged in the cavity in the heat dissipation fins, and the heat dissipation of the heating component is controlled by controlling the opening or closing of the fan assembly and / or controlling the rotating speed of the fan assembly when the fan assembly is opened. According to the controller heat dissipation assembly, air flow can be sucked or blown out from the interiors of the heat dissipation fins, local high-temperature points of components can be reduced, the problems that the temperature of the components of an air conditioner variable frequency controller is too high and the temperature of the components is uneven and inconsistent are solved, and meanwhile a system is fed back and adjusted according to the operation condition of the fan assembly in a radiator, and the temperature of the component is ensured to be within a reasonable range.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a controller cooling component, a control method and an air conditioner. Background technique [0002] Most of the existing air-conditioning frequency conversion controller components use aluminum radiators for heat dissipation. On the one hand, in high-temperature environments, the temperature rise of the controller components cannot meet the requirements, which limits the improvement of the high-temperature cooling capacity of the air conditioner, and even protects the air conditioner from shutting down. On the one hand, due to the inconsistent heat generation of components, the temperature uniformity of components cannot be guaranteed, and the temperature of some components is too high, which affects their reliability and life, which in turn affects the safety and reliability of air conditioner operation. [0003] Because the air conditioner in the prior a...
