Power-driven compressor capable of preventing overheating of control circuit

Abstract

The invention discloses a power-driven compressor capable of preventing the overheating of a control circuit, which comprises a shell, a control circuit accommodating box and a communication pipe, wherein a transmission component and a compression component are arranged inside the shell, and an air inlet and a coolant outlet are formed on the shell; the control circuit accommodating box is arranged on the shell and is provided with a coolant inlet and an air outlet; and one end of the communication pipe is connected to the air outlet of the control circuit accommodating box, and the other end of the communication pipe is connected to the air inlet of the shell. When the transmission component is driven by electric power, coolant enters the control circuit accommodating box from the coolant inlet of the control circuit accommodating box and is guided into the shell to be compressed from the air outlet, the communication pipe and the air inlet of the shell, and the compressed coolant is discharged outwards from the coolant outlet of the shell.

Description

technical field [0001] The present invention relates to a compressor device, in particular to an electrically driven compressor capable of avoiding overheating of a control circuit. Background technique [0002] At present, the general car compressor system uses a gasoline engine to drive its compressor to run synchronously; however, due to the rising oil price and the exhaustion of other limited resources such as oil, various car manufacturers are making great efforts It is an inevitable trend to change the compressor system used in vehicles to be driven by all electric power in the research and development of vehicles powered by all electric power. [0003] However, the current compressor systems driven by electricity (such as refrigerators and other household appliances) cannot be directly transferred to vehicles for the following reasons: [0004] 1. Due to the high ambient temperature caused by the running of the vehicle, it is easy to cause the compressor motor to ove...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the high ambient temperature caused by the operation of the vehicle, it is easy to cause the compressor motor to overheat and result in a decrease in performance, and the working environment with too high temperature can easily cause damage to the relevant start-up circuit of the compressor system

[0005] 2. The compressor system for general household appliances has a chamber at the bottom that can be filled with refrigerated oil, so that the compressor can simultaneously suck up the refrigerated oil and use it to lubricate the internal components of the compressor when the compressor is running. The compressor system must be in a static environment, so as not to cause damage to the internal components of the compressor due to insufficient lubrication due to the inability to absorb the refrigerating oil. not applicable to vehicles
