The present disclosure provides a heat dissipation module and equipment cabinet, the heat dissipation module comprises a fan assembly; a heat conduction assembly is tightly connected with the fan assembly along a first direction; a rotating support is connected with the fan assembly along the first direction and can rotate around an axis relative to the fan assembly, the rotating support is matched with the heat conduction fins of the heat conduction assembly through a folded edge structure and is tightly connected with the heat conduction fins along a second direction to press the folded edge structure; wherein the first direction and the second direction satisfy the perpendicular condition. The heat dissipation module and equipment cabinet of the present disclosure connect the fan assembly and the heat conduction assembly together by setting the rotating support, the rotating support is rotationally connected with the fan assembly and is tightly connected with the heat conduction fins of the heat conduction assembly along the second direction, the torsion generated in the process of tightening drives the rotating support to rotate upward relative to the fan assembly to press the folded edge structure and ensure that the corresponding part of the heat conduction fins is always in the best position of the air inlet of the fan assembly.

The application relates to the technical field of LED lamps, in particular to an LED lamp which comprises a shell and an LED lamp plate arranged in the inner cavity of the shell, and a gap for air circulation is formed between the panel edge of the LED lamp plate and the inner wall of the shell. The application creates a natural air circulation channel in the lamp shell by reserving the gap between the LED lamp plate edge and the shell inner wall, allows the internally accumulated hot air to naturally convect outward through the gap, and meanwhile, the cooler air outside can also supplement into the gap, forming a passive heat dissipation air duct. This effectively alleviates the problem of internal heat accumulation caused by the closure of the shell, reduces the operating temperature of the LED lamp plate and electronic components, slows down the thermal aging, and significantly improves the service life and light efficiency stability of the lamp in an outdoor closed environment.

The application discloses an air conditioner and belongs to the technical field of air conditioners. The air conditioner comprises: a refrigerant circulation loop, which circulates refrigerant in a loop composed of a compressor, an outdoor heat exchanger, an expansion valve, an indoor heat exchanger and a gas-liquid separator; and a controller, which is configured to, in the starting stage and the transition stage of the air conditioner: acquire suction superheat of the compressor, calculate the refrigerant density p in the suction pipe according to the dynamic pressure of the suction port of the compressor, and calculate the suction dryness of the compressor according to the refrigerant property parameters; determine whether the compressor has a liquid strike risk according to the suction superheat and the suction dryness; if the liquid strike risk does not exist, control the opening degree of the expansion valve according to a preset control logic; and if the liquid strike risk exists, control the opening degree of the expansion valve to decrease or control the air conditioner to stop, so that the problem of the compressor liquid strike that is prone to occurring after low-temperature heating sleep starting or after starting after severe defrosting is effectively solved.
