Description
Technical field
The present invention relates to the relay technical field, be specifically related to a kind of radiator structure of electromagnetic relay.
Background technology
As everyone knows, relay is the power-type device, and coil has several watts power when it is worked.When under conditions of air is arranged, working, the heat of its generation can carry out heat loss through conduction through media such as air.But, when relay under vacuum environment, do not had the medium of heat loss through conduction, the heat of its generation just can not leave timely and effectively, so just greatly reduces the dependability and the useful life of relay, even causes relay to lose efficacy because of overheated.Be welded on the relay on the printed wiring board for there not being mounting panel, must increase heat abstractor.
Summary of the invention
To above-mentioned technical problem, the object of the present invention is to provide a kind of radiator structure that makes the electromagnetic relay that electromagnetic relay can obtain dispelling the heat under vacuum working environment, avoid electromagnetic relay to lose efficacy because of overheated.The technical scheme that realizes above-mentioned purpose is following:
The radiator structure of electromagnetic relay; The heat sink that comprises casing and be arranged in casing; This heat sink comprises heat conduction baffle, Endothermic Block, heat pipe and the radiating tube that is arranged in the casing, forms the vacuum assembly cavity of relay between heat conduction baffle lower surface and the casing diapire, and heat conduction baffle upper surface and casing form thermal conductive cavity between facing the wall and meditating; Endothermic Block is fixed on the upper surface of heat conduction baffle; One end of heat pipe is connected with Endothermic Block, and the other end of heat pipe is connected with radiating tube, and radiating tube is positioned at the outside of casing.
Adopted such scheme; The heat that produces during electromagnetic relay work can be dispersed in the vacuum assembly cavity; Be delivered on the Endothermic Block after by heat conduction baffle the heat in the vacuum assembly cavity being absorbed; Again by heat pipe with the heat transferred on the Endothermic Block to radiating tube, carry out heat exchange by flow air and radiating tube at last, take away the heat on the radiating tube.Can in time electromagnetic relay work be produced the heat of giving birth to through the present invention and take away, avoid electromagnetic relay to lose efficacy because of overheated.
Further; Said radiator structure also comprises the air blast cooling radiator cooler; This air blast cooling radiator cooler comprises fan, temperature sensor and controller, and said fan is assemblied in the thermal conductive cavity, and temperature sensor is assemblied in the vacuum assembly cavity; Fan is connected the output of controller, and temperature sensor is connected the input of controller.Detect the temperature in the vacuum assembly cavity through temperature sensor; After controller obtains the actual temp value of vacuum assembly cavity, compare with the temperature value that is provided with in the controller, if detected value is equal to or higher than set point; Then explain through heat sink and can not satisfy the heat radiation requirement; Then controller output signal starts fan air blast cooling is carried out but in the heat radiation chamber, to accelerate the heat radiation of heat sink to fan.If detected value is lower than set point, then explanation can be satisfied the heat radiation requirement through heat sink, need not to start fan and carries out air blast cooling but.The present invention is a heat sink because of the heat radiation weak point remedies through the air blast cooling radiator cooler, to guarantee electromagnetic relay a good working environment is arranged.
