A box body is internally provided with a heat conduction mounting seat, a back face of the heat conduction mounting seat is provided with a disc-shaped pipeline which is connected with a cooling pump, the cooling pump is connected with a liquid reservoir tank stored with cooling liquid, the box body is internally provided with a temperature sensor which is connected with a controller, an output end of the controller is connected with a driver, and the driver is connected with the cooling pump. The heat radiation device of the large power relay has advantages of small volume, light weight and good heat radiation effect.
Description
Technical field
The utility model relates to the relay technical field, is specifically related to a kind of heat abstractor of high power relay.
Background technology
Traditional radiator is heat conduction carrier mainly with metal greatly, such as aluminium radiator fin, copper, iron fin, the rate of heat dissipation of this radiator depends on the conductive coefficient of metal material, in order to improve the heat radiation requirement, can only be by increasing area of dissipation, increase the radiator volume and realize, cause product heavy, cost improves.
Summary of the invention
For above-mentioned technical problem, the purpose of this utility model is to provide that a kind of volume is little, lightweight, the heat abstractor of the high power relay of good heat dissipation effect.
The technical scheme that realizes above-mentioned purpose is as follows:
The heat abstractor of high power relay, be provided with the heat conduction mount pad in the casing, the back side of this heat conduction mount pad is provided with the dish type pipeline, the dish type pipeline is connected with coolant pump, coolant pump is connected with a liquid reserve tank that has cooling liquid, is provided with temperature sensor in casing, and temperature sensor is connected with a controller, the output of this controller connects driver, and driver is connected with coolant pump.
Adopted such scheme, owing to heat can be delivered on the heat conduction mount pad during relay work, the utility model is by detecting the temperature on the heat conduction mount pad, start coolant pump work so that the heat conduction mount pad is dispelled the heat, so in time heat is taken away, made relay be in good operational environment.The utility model is comprised of several simple parts, has the advantage of take up room little, lightweight and good heat dissipation effect.
Also connect an auxiliary radiating device on the heat conduction mount pad, this auxiliary radiating device comprises heat pipe and is positioned at the outer radiating tube of casing, and an end of heat pipe is connected with the heat conduction mount pad, and the other end of heat pipe is connected with radiating tube.By auxiliary radiating device a part of heat on the heat conduction mount pad directly is dispersed in the air, for the heat radiation of relay further provides guarantee.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is casing, and 2 are the heat conduction mount pad, and 3 are dish 1 shape pipeline, and 4 is coolant pump, and 5 is liquid reserve tank, and 6 is temperature sensor, and 7 is controller, and 8 is driver, and 9 is heat pipe, and 10 is radiating tube.
Embodiment
With reference to Fig. 1, the heat abstractor of high power relay of the present utility model, be provided with heat conduction mount pad 2 in the casing 1, the back side of this heat conduction mount pad is provided with dish type pipeline 3, and dish type pipeline 3 is connected with coolant pump 4, and coolant pump 4 is connected with a liquid reserve tank 5 that has cooling liquid, in casing, be provided with the temperature sensor 6 that detects temperature on the heat conduction mount pad, temperature sensor 6 is connected with a controller 7, and temperature sensor 6 passes to controller 7 with the temperature signal that detects, and controller 7 is 51 series monolithics.The output of controller 7 connects driver 8, driver 8 is connected with coolant pump 4, in controller, be preset with temperature value, when the temperature in the casing is higher than this default temperature, then controller output signal is to driver, and driver outputs to coolant pump after signal is amplified, and starts coolant pump work, coolant pump carries out material recycle with the cooling liquid in the liquid reserve tank, takes away the heat on the heat conduction mount pad 2.Also connect an auxiliary radiating device on the heat conduction mount pad 2, this auxiliary radiating device comprises heat pipe 9 and is positioned at the outer radiating tube 10 of casing, and an end of heat pipe 9 is connected with the heat conduction mount pad, and the other end of heat pipe is connected with radiating tube.By auxiliary radiating device, a part of heat on the heat-conducting seat can be discharged in the air, to alleviate the burden of the heat conduction mount pad being dispelled the heat by the cooling liquid mode.
