The application provides a compressor top cover and a compressor. The compressor top cover is used for a compressor and comprises a mounting end face facing a static scroll. The mounting end face is provided with a first exhaust cavity, a second exhaust cavity and a flow-through port. The first exhaust cavity and the second exhaust cavity are arranged at intervals. Part of gas can enter the second exhaust cavity which is in communication with the first exhaust cavity, so that a certain buffering and noise reduction effect is achieved. The compressor top cover is further provided with an exhaust passage. The exhaust passage is in communication with the second exhaust cavity and extends through the compressor top cover to form an exhaust port. The gas flows out of the exhaust port after being buffered by the second exhaust cavity. The compressor top cover is further provided with an oil return port which is in communication with the first exhaust cavity and the second exhaust cavity. Along the direction of gravity, the exhaust port, the flow-through port and the oil return port are arranged in sequence. When the gas enters the second exhaust cavity from the first exhaust cavity, the cooling oil can flow from the oil return port to the second exhaust cavity along with the gas flow, so that further collection of the cooling oil is realized.

This application discloses a three-phase multi-position metal metering box, specifically relating to the field of metering box technology. The device includes a metering box with an internal heat dissipation mechanism, a dehumidification mechanism, and a cleaning mechanism for cleaning a dust filter. When the dust filter becomes clogged, a drive motor rotates a threaded rod. A slider is threadedly connected to the surface of the threaded rod, and a brush is fixedly connected to the surface of the slider. When the threaded rod rotates, the slider moves up and down, moving the brush. This brush movement cleans the surface of the dust filter, removing dust, lint, and small insects adsorbed on the filter surface, thus preventing clogging and ensuring effective heat dissipation from the ventilation holes.

The utility model relates to the technical field of bus ducts, and discloses a heat dissipation type bus duct, which comprises a main body mechanism and an auxiliary mechanism, the auxiliary mechanism is arranged at the outer side of the main body mechanism, the main body mechanism comprises a bus duct body, a plug-in groove and a heat dissipation sheet, the plug-in groove is fixedly arranged at the outer end of the bus duct body, and the heat dissipation sheet is arranged in the plug-in groove. The cooling fins are fixedly installed in the bus duct body, and the main body mechanism further comprises a dustproof plate, a plate type cooling fan, a first connector side plate and a second connector side plate. According to the heat dissipation type bus duct, by installing the main body mechanism, in the use process of the bus duct body, circulation of gas in the bus duct body is promoted through the design of the heat dissipation fins and the plate type heat dissipation fan, input gas can be filtered through the design of a dustproof plate, and it is avoided that dust and impurities enter the bus duct body to affect normal operation of the bus duct body; meanwhile, too much dust attached to the surfaces of the cooling fins can be prevented from affecting the cooling effect, and the practicability and protection performance of the bus duct body are improved.
