Problems solved by technology

But, there is following problem in this prior art variable frequency air conditioner outdoor unit: as everyone knows, the variable frequency controller that is installed on the printed circuit board 8 can produce a large amount of heat in the running process of air conditioner, therefore needs fan 10 to cool down , to increase its working current and the operating frequency of the variable frequency compressor
But because the fan 10 sends the outside air into the inside of the box body 6, its cooling effect changes with the temperature of the outside air, so sometimes the cooling speed is slow, so that the maximum operating frequency of the inverter compressor is not high, resulting in Insufficient output capacity to meet requirements

Abstract

The invention discloses a variable frequency air conditioner outdoor unit, which comprises a shell, a chassis, a constant speed compressor and an inverter compressor, an outdoor heat exchanger, an expansion valve, a fan assembly, a baffle and a controller; wherein, the controller consists of a box body, an electronic component arranged in the box body, a fan and a hood; a tubule adjacent to the fan is connected with in parallel the coolant pipe which is arranged among the indoor heat exchanger, the constant speed compressor and the inverter compressor. The tubule is connected with in parallel the coolant pipe between the indoor heat exchanger and the compressor, and the tubule is arranged at the exhaust inlet of the fan of the control box, therefore, the low-temperature coolant which flows through the tubule can be used to cool the outdoor air near the exhaust inlet, thus reducing the temperature of the air into the control box provided by the fan, and effectively reducing the temperature of the variable frequency controller; thereby the maximum operating frequency of the inverter compressor can be improved to meet the requirement for output capacity.

Description

technical field [0001] The invention relates to an outdoor unit of an air conditioner, in particular to an outdoor unit of an inverter air conditioner. Background technique [0002] Generally, an air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, a condensation process, an expansion process, and an evaporation process. Air conditioners and inverter air conditioners are composed of outdoor units and indoor units. figure 1 It is a structural schematic diagram of the main components in the outdoor unit of the frequency conversion air conditioner in the prior art. Such as figure 1 As shown, the outdoor unit of the frequency conversion air conditioner in the prior art mainly includes a housing that constitutes the top surface and side external structure of the outdoor unit not shown in the figure; it is arranged at the lower end of the housing and can install various components of the out...
