Problems solved by technology

[0002] At present, the controllers of some air source heat pump heating units are installed in the control box inside the casing of the heat pump heating unit. Due to structural limitations, the size of the radiator used by the controller is limited, and the cooling effect is limited. less, increasing the heat sink can not increase the heat dissipation effect, causing the controller to be prone to the frequency limit of the compressor because the temperature of the controller is too high, resulting in the heating capacity not meeting the requirements
[0003] In order to solve the situation that the temperature of the power components of the controller is too high, some air source heat pump air conditioners currently use a guide ring at the radiator of the controller power module to guide the wind to the evaporator of the heat pump. The air volume is used to improve the heat exchange efficiency of the radiator, but because the controller is a certain distance from the evaporator, the heat dissipation effect is limited

Abstract

The invention discloses a heat pump unit and a heat dissipation control method of a controller, and the heat pump unit comprises a controller which is used for controlling the heat pump unit to work; a control box, in which the controller is installed, and is provided with an opening; a radiator which is arranged opposite to the opening and is used for radiating the controller; and a cover shell which is arranged on the opening in a covering mode to form an independent air duct circulating with the outside, wherein a heat dissipation fan is arranged on the independent air duct. The opening is formed in the control box, the cover shell covers the opening to form the independent air duct, and the cooling fan is arranged on the independent air duct, so that the air flow in the independent air duct is increased, the cooling efficiency of the radiator is improved, the cooling capacity of the radiator to the controller is increased, the temperature of the controller is reduced, and the problem of compressor frequency limitation caused by over-high temperature of the controller is prevented, so that the working efficiency of the heat pump unit is improved.

Description

technical field [0001] The invention belongs to the field of heat pumps, and in particular relates to a heat dissipation control method for a heat pump unit and a controller. Background technique [0002] At present, the controllers of some air source heat pump heating units are installed in the control box inside the casing of the heat pump heating unit. Due to structural limitations, the size of the radiator used by the controller is limited, and the cooling effect is limited. Even increasing the radiator will not increase the heat dissipation effect, which will cause the controller to be prone to frequency limitation of the compressor because the temperature of the controller is too high, resulting in the heating capacity not meeting the requirements. [0003] In order to solve the situation that the temperature of the power components of the controller is too high, some air source heat pump air conditioners currently use a guide ring at the radiator of the controller pow...
