The profile is formed by extruding and stretching a die; an evaporation cavity is arranged inside the profile; toothed radiating fins are arranged outside the profile; two ends of the evaporation cavity are closed by the end covers; the work media are filled inside the evaporation cavity; and the power device mounting base plate is arranged on one side of the profile. The sectional shape of the evaporation cavity is a combined shape of a cone and a sphere; the shapes of the end covers on two sides match with the sectional shape of the evaporation cavity; a bleeder hole is arranged on the mounting base plate; sealing holes are arranged on the end covers; all the bleeder hole and the sealing holes adopt sealing dowels for closing; and the radiator composed of the profile can be in a unit structure or an expanding structure composed of a plurality of units. Compared with the prior art, the heat pipe principle profile-type superconducting radiator has the advantages of integrating the profile and a heat pipe, effectively using the working principle of the heat pipe to substantially reduce heat resistance and being low in cost, simple in structure and flexible in use direction.
Description
Technical field
The utility model relates to a kind of heat abstractor that is used for power electronic device, particularly a kind of heat pipe principle section bar formula superconducting radiator.
Background technology
At present, the heat radiation of power device is adopted solid profile, heat pipe or water-cooled box to make radiator usually and is solved heat dissipation problem.Because the development of power device technology, can the capacity of IGBT, IGCT, IEGT, rectifying tube and thyristor be increasing, make power device reliability service under specified junction temperature condition, and it is very important effectively solving heat dissipation problem.The subject matter that traditional entity metal, heat-pipe radiator exist is: itself heat-transfer capability is restricted, be difficult to solve the heat dissipation problem of high-capacity power device, heat-pipe radiator manufacturing process complexity, the cost height, and the complete set of equipments cost height of employing water-filled radiator, easily leak in the water route, directly influences the reliability of electric equipment operation.

For achieving the above object, the utility model is realized by the following technical solutions:
Heat pipe principle section bar formula superconducting radiator, comprise section bar, end cap, installation base plate, working media, described section bar is by the moulding of mould extrusion stretching, section bar is inner to be that evaporation cavity, outside are the profile of tooth fin, evaporation cavity two ends are sealed by end cap, inside is marked with working media, and section bar one side is provided with the power device installation base plate.
The section shape of described evaporation cavity be cone and spheroid in conjunction with shape, the end covers at two sides shape with the evaporation cavity section shape match.
The heat spreader structures that described section bar is formed can be the expansion structure of cellular construction or a plurality of unit composition.
Described installation base plate is provided with aspirating hole, adopts the seal pin sealing.
Described end cap is provided with closed hole, adopts the seal pin sealing.
Compared with prior art, the invention has the beneficial effects as follows: integrated section bar and heat pipe effectively utilize the heat pipe operation principle in one, thermal resistance is reduced significantly, and cost is low, and simple in structure, service orientation is flexible, substitutes solid profile, heat pipe or water cooling method comprehensively.
