Problems solved by technology

[0003] However, when the outdoor unit is working, the fan runs at high speed, and the air passes through the heat exchanger from the rear side of the outdoor unit and directly enters the interior of the outdoor unit casing. This part of the air will collide with the air entering from the air inlet on the front panel, Because the kinetic energy of this part of the air is large, it will collide with the air flowing in from the air inlet, so that the air entering from the air inlet rarely even reaches the cooling fins, so the cooling effect on the PCB board is limited and the practicability is poor.

Abstract

The invention discloses an outdoor unit of an air conditioner. The outdoor unit comprises an outdoor unit shell, an electric control box and an isolating part, wherein the outdoor unit shell comprises a front panel; the front panel is provided with a front panel air inlet; the electric control box is arranged in the outdoor unit shell, and comprises an electric control box shell, a PCB (Printed Circuit Board) and a radiator; the PCB is arranged in the electric control box shell; the radiator is connected with the PCB; a part of the radiator extends out of the electric control box shell; the isolating part coats the outside of a part, which extends out of the electric control box shell, of the radiator; an isolating part air inlet and an isolating part air outlet are formed in the isolating part; the air inlet of the isolating part is in hermetic fit with the front panel, and the isolating part air inlet is opposite to the front panel air inlet; the isolating part air outlet is communicated with the inside of the outdoor unit shell. The outdoor unit of the air conditioner disclosed by the invention has an improved heat dissipation structure, so that the heat dissipation effect of the PCB in the electric control box is enhanced.

Description

technical field [0001] The invention relates to the technical field of air conditioner construction, in particular to an outdoor unit of an air conditioner. Background technique [0002] Traditional inverter air conditioners are equipped with an electric control box inside the outdoor unit. The electric control box is equipped with a PCB board and a radiator for cooling the PCB board. The heat dissipation fins of the radiator protrude downward from the bottom of the electric control box. Conducive to heat dissipation, in order to increase the heat dissipation effect, there is an air inlet on the front plate of the outdoor unit housing corresponding to the cooling fins, and the air enters the outdoor unit housing through the air inlet to cool the rear cooling fins and increase the heat dissipation of the PCB board. cooling effect. [0003] However, when the outdoor unit is working, the fan runs at high speed, and the air passes through the heat exchanger from the rear side o...
