Abstract

The invention relates to a cooler of broadcast emitter and electric high-power element. Wherein, the outdoor machine is outside the room, and the indoor machine is inside the frame of television and broadcast emitter; the upper wind open of vaporizer of indoor machine is connected to the bottom support of power amplifier of emitter; the coolant outlet of vaporizer is connected to the gas reflux tube of outdoor machine and connected to the liquid outlet tube of outdoor machine; the ventilating valve is at the top of power amplifier; the condense water of vaporizer and the water outlet tube are in the outdoor condition A. the invention can use circulated wind to cool inside the frame or use natural wind.

Description

technical field [0001] The invention relates to a radio and television transmitter and an electronic high-power component refrigeration air circulation natural wind compatible cooling device, which is mainly used in radio and television transmitters and electronic equipment high-power devices, component cooling and the like. Background technique [0002] At present, the heat dissipation and cooling system of high-power devices and components of traditional radio and television transmitters and other electronic equipment is cooled by natural wind, as shown in Figure 1: A is the outdoor environment, and B is the indoor environment. Place the air duct in the cabinet and connect it to the bottom of the high-power device components. When electronic equipment such as broadcasting and TV transmitters are working, the fan will suck in the air at room temperature and change the direction through the air duct and the air outlet to cool the high-power device components. After the hot w...
