Description
Technical field
The utility model relates to a kind of rectifier bridge, belongs to field of semiconductor devices.
Background technology
Rectifier bridge is as one of rectifying component, and it is the key factor that concerns rectifier bridge reliability that the junction temperature of its inner rectification chip is controlled.If junction temperature is too high, will cause rectification chip generation thermal breakdown to be lost efficacy, thereby make rectifier bridge lose rectification function, therefore, the junction temperature of controlling rectification chip is most important.For the rectifier bridge being applied in Domestic electric appliances power source device, prior art is often by close rectifier bridge place mounting temperature sensor on substrate, for monitoring the temperature rise of rectifier bridge, but the junction temperature true temperature of the inner rectification chip of the temperature that this mode records and rectifier bridge differs greatly, unreliable.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of rational in infrastructure, good heat dissipation effect, the rectifier bridge that reliability is strong.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: rectifier bridge, comprise: rectifier bridge body and packaging body, described rectifier bridge body is placed in package interior, pin is positioned at the below of packaging body, the top of described packaging body is provided with the through hole being connected with rectifier bridge body, in described through hole, heat carrier is installed, the upper surface of heat carrier and rectifier bridge body is provided with heat-conducting silicone grease layer, heat carrier top is provided with gland, described gland is fixed on packaging body, and described heat carrier top is provided with a plurality of thermal columns.
Preferably, the both sides of described packaging body are provided with a plurality of radiating fins.
Preferably, described heat carrier or be square or for triangle, or be polygon.
The utility model is simple and reasonable for structure, installation heat carrier is inlayed in employing in packaging body, make the heat on rectifier bridge body can be directly passed to heat carrier, between rectifier bridge body and heat carrier, install heat-conducting silicone grease layer additional, and adopt gland to compress, and rectifier bridge body is contacted with heat carrier better, strengthen heat transfer effect, then by thermal column, carry out quick heat radiating, radiating fin also can play the effect of heat radiation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is rectifier bridge body, 2 is packaging body, and 3 is pin, and 4 is through hole, and 5 is heat carrier, and 6 is heat-conducting silicone grease layer, and 7 is gland, and 8 is thermal column, and 9 is radiating fin.
Embodiment
The specific embodiment of the utility model being done below in conjunction with accompanying drawing is described further.
As shown in Figure 1, rectifier bridge, comprise: rectifier bridge body 1 and packaging body 2, rectifier bridge body 1 is placed in packaging body 2 inside, pin 3 is positioned at the below of packaging body 2, the top of described packaging body 2 is provided with the through hole 4 being connected with rectifier bridge body 1, heat carrier 5 is installed in through hole 4, the upper surface of heat carrier 5 and rectifier bridge body 1 is provided with heat-conducting silicone grease layer 6, the part top that heat carrier 5 exposes packaging body 2 is provided with gland 7, gland 7 centers have through hole, this through-hole diameter is more smaller than the diameter of heat carrier 5, and heat carrier 5 is not blocked in the both sides of gland 7, be fixed by screws on packaging body 2, heat carrier 5 tops are provided with a plurality of thermal columns 8, gland 7 compresses heat carrier 5, make the upper surface of heat carrier 5 and rectifier bridge body 1 in conjunction with tightr, heat-conducting effect is stronger, rectifier bridge body 1 transfers heat to heat carrier 5, and dispel the heat by thermal column 8, heat carrier 5 directly contacts with rectifier bridge body 1, good heat dissipation effect, wherein heat carrier 5 can adopt square cylinder, triangle cylinder or polygon cylinder, be conducive to heat radiation.The both sides of packaging body 2 are provided with a plurality of radiating fins 9, also can play radiating effect.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken possessing those of ordinary skills; the various variations that can also make under the prerequisite that does not depart from the utility model aim, also should be considered as protection range of the present utility model.
