Cooling device of outdoor unit heat dissipation plate of heat pump water heater and cooling method therefor

Abstract

The invention discloses a cooling device of an outdoor unit heat dissipation plate of a heat pump water heater and a cooling method therefor. The cooling device comprises an outdoor unit shell; a circulating pipeline is arranged in the outdoor unit shell; a plurality of vertical heat dissipation plates are arranged on the outer surface of the circulating pipeline and located on the back surface of an inner cavity of the outdoor unit shell; a support frame is fixedly connected to the top of the inner cavity of the outdoor unit shell; and a motor is fixedly connected to the front surface of the support frame. An air blowing box is arranged in the outdoor unit shell and connected with a storage box through a connecting assembly; volatile cooling liquid is placed in the storage box; by opening an electromagnetic control valve, cooling liquid enters a first air inlet pipe and a second air inlet pipe; the cooling liquid is blown to the position between the two vertical heat dissipation plates through an air blowing opening in a ventilation block by means of an electric fan, so that heat on the surfaces of the vertical heat dissipation plates is absorbed and blown out through rotating air blowing fan blades; and by means of the structure, the heat dissipation plates can be rapidly cooled, and popularization is easy.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a cooling device and a cooling method for a cooling plate of an external unit of a heat pump water heater. Background technique [0002] A heat pump water heater is a device that uses the reverse Carnot principle to transfer heat from a low-temperature object to high-temperature water through a medium. The heat pump device can change the phase of the medium (refrigerant) to become lower than the low-temperature heat source, thereby spontaneously absorbing the heat of the low-temperature heat source; the medium returned to the compressor is compressed into a high-temperature (higher than high-temperature water) high-pressure gas , so as to spontaneously emit heat to a high-temperature heat source; realize the "transfer" of heat from a low-temperature heat source to a high-temperature heat source. [0003] At present, the heat dissipation plate in the external unit of the...

AI Technical Summary

Problems solved by technology

[0003] At present, the heat dissipation plate in the external unit of the heat pump water heater only takes away the heat by blowing the fan blades to rotate. It is taken away by the airflow, only a small amount of airflow is blown between the two heatsinks on the side of the heatsink on the inner wall of the outer casing, and the heat dissipation efficiency is poor.
