Description

Section bar formula superconducting radiator

Technical field

The utility model relates to a kind of heat abstractor that is used for power electronic device, particularly a kind of 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.

The utility model content

For addressing the above problem, the purpose of this utility model provides a kind of good heat conductivity, thermal resistance is little, cost is low, integrated section bar and heat pipe be in the section bar formula superconducting radiator of one.

For addressing the above problem, the utility model by the following technical solutions:

A kind of section bar formula superconducting radiator comprises section bar, end cap and working media, comprises section bar, end cap and working media, and section bar one side is provided with the electrical device installed surface, and opposite side is provided with the profile of tooth fin, and section bar inside is provided with pipeline; Pipe ends is sealed by end cap, and pipe interior is marked with working media.

Described section bar according to the heat radiation power requirement, can be provided with one or more pipelines by the moulding of mould extrusion stretching, and the quantity of profile of tooth fin, and the closed cavity that pipeline and end cap form is a vacuum cavity, and inside is marked with working media.

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, and thermal resistance is reduced significantly, and cost is low, and simple in structure, substitute solid profile, heat pipe or water cooling method comprehensively.
