Air conditioning outdoor unit

Abstract

The invention discloses an air conditioning outdoor unit which comprises an outdoor unit shell, an L-shaped heat exchanger, a draught fan, a middle separation plate, a compressor and a variable-frequency electric control box space. The air conditioning outdoor unit is characterized in that the included angle between the axis lead of a rotary shaft of a fan motor and the center line of the long straight plate segment of the L-shaped heat exchanger is smaller than or equal to 85 degrees, an induced air channel air inlet is formed in a fan air outlet, and an induced air channel penetrates the middle partition plate and communicates with the compressor and the variable-frequency electric control box space; in the projection face which is the plane formed by the fan air outlet, the projection, on the projection plane, of the plane formed by the induced air channel air inlet and the projection, on the projection plane, of the plane formed by the fan air outlet form an overlapped face; and an air outlet is formed in the outdoor unit shell, and fan outflow air enters the compressor and the variable-frequency electric control box space through the induced air channel, flows through the compressor and a variable-frequency electric control box and then is discharged out of the outdoor unit through the air outlet. The variable-frequency electric control box and the compressor are cooled under the condition that no energy consumption is increased, the performance of the compressor and the performance of the variable-frequency electric control component are improved, the service life of the compressor and the service life of the variable-frequency electric control component are prolonged, and compared with an existing air conditioning outdoor unit with the same draught fan and the same L-shaped heat exchanger, the air conditioning outdoor unit has the beneficial effect that the heat exchange efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and only relates to an outdoor unit of an air conditioner. Background technique [0002] The existing split-type air conditioner includes an indoor unit and an outdoor unit. When cooling, the indoor unit is an evaporating unit, which absorbs heat by evaporating, and the outdoor unit is a condensing unit, which condenses and releases heat. On the contrary, when heating, the indoor unit is a condensing unit. Condensation releases heat, and the outdoor unit is an evaporation unit, which absorbs heat through evaporation. The condenser and evaporator in the unit are collectively referred to as heat exchangers. There are many types of structure for the outdoor unit of the air conditioner, among which the axial flow fan is used to enter and exit the air. The structure is the most common air conditioner outdoor unit structure. This kind of air conditioner outdoor unit is usually in the shape o...

Problems solved by technology

Therefore, on the basis of the existing air conditioner, it is necessary to design a heat dissipation method that does not increase the production cost, does not consume electricity to increase the cost of heat dissipation, and has no hidden danger of short circuit burnout for the frequency conversion module, and the heat dissipation effect is doubled. become the technical problem that people have always wanted to solve but never succeeded in
