Abstract
The utility model provides a copper bar of an IGBT (insulated gate bipolar transistor) intermediate frequency power supply, which comprises a body, wherein a cooling tube is welded on the side surface of the body, and a copper tube is taken as the cooling tube. In the work process of the IGBT intermediate frequency power supply, circulating cooling water in the cooling tube can absorb the heat of the copper bar, thereby achieving the effects of cooling the copper bar and quickening the heat dissipation of the copper bar.
Description
Technical field
The utility model relates to a kind of copper bar of intermediate frequency power supply, relates in particular to a kind of copper bar of IGBT intermediate frequency power supply.
Background technology
Intermediate frequency power supply is a kind of static frequency-conversion device; Three phase worker power is transformed into single phase poaer supply, is mainly used in the melting, insulation, sintering, welding, quenching, tempering of various metals, diathermanous, molten metal purification, heat treatment, bend pipe and crystal growth etc.The IGBT intermediate frequency power supply be a kind of be the novel intermediate frequency power supply of inversion device with the IGBT module; Adopt the electric induction furnace of IGBT intermediate frequency power supply; Workpiece is put in the inductor, and inductor generally is the hollow copper tubing of input intermediate frequency or high-frequency alternating current (1000Hz-300000Hz or higher).Produce alternating magnetic field produces same frequency in workpiece induced current, this induced current is uneven in the distribution of workpiece, and is strong on the surface; And inside very a little less than; Portion approaches 0 to the heart, utilizes this kelvin effect, and surface of the work is heated rapidly; In seconds surface temperature rises to 800-1000 degree centigrade, and the temperature rising of heart portion is very little.
Each components and parts of IGBT intermediate frequency power supply connect through copper bar, and in IGBT intermediate frequency power supply running, copper bar can produce great amount of heat; In the prior art; All adopt the copper bar natural heat dissipation, radiating effect is undesirable, because copper bar is overheated; Influence the performance of each components and parts, cause IGBT intermediate frequency power supply fluctuation of service.
The utility model content
The utility model is in order to solve in the prior art the slow problem of copper bar heat radiation in the IGBT intermediate frequency power supply, a kind of device of copper bar heat radiation of the IGBT of quickening intermediate frequency power supply to be provided.
In order to address the above problem, the copper bar of a kind of IGBT intermediate frequency power supply that the utility model provides comprises body, said body side welding cooling water pipe, and said cooling water pipe is a copper pipe.In the IGBT intermediate frequency power supply course of work, the recirculated cooling water in the cooling water pipe can absorb the heat of copper bar, reaches to the copper bar cool effect, accelerates the copper bar heat radiation.
As preferably, the internal diameter of said cooling water pipe is 12 millimeters.Internal diameter is that 12 millimeters copper cooling water pipe is convenient to buying, and good cooling results is avoided unnecessary waste.
The utility model adopts technique scheme, obtains following beneficial effect:
1, compared with prior art, on the copper bar of the IGBT intermediate frequency power supply of the utility model cooling water pipe is set, the recirculated cooling water in the cooling water pipe can be taken away the heat of copper bar, reaches to the copper bar cool effect, accelerates the copper bar heat radiation.
2, cooling water pipe and copper bar same material are convenient to welding.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the copper bar structure chart of a kind of IBGT intermediate frequency power supply of the utility model
Fig. 2 be among Fig. 1 A-A to cutaway view
Embodiment
Fig. 1, shown in Figure 2, a kind of copper bar of IGBT intermediate frequency power supply comprises body 1, and body 1 is the rectangular copper coin of cross section, and the middle and upper part of body 1 side is welded with cooling water pipe 2, and cooling water pipe 2 is the copper pipe of 12 millimeters of internal diameters.When the IGBT intermediate frequency power supply is worked, feed the cooling water of circulation in the cooling water pipe, cooling water can absorb the heat of copper bar and discharge, and reaches to the copper bar cool effect, accelerates the copper bar heat radiation.
Experiment showed, that when the IGBT intermediate frequency power supply is worked the copper bar of the utility model IGBT intermediate frequency power supply descends 20 ℃-25 ℃ than the copper bar surface temperature of IGBT intermediate frequency power supply in the prior art.
Claims (2)
1. the copper bar of an IGBT intermediate frequency power supply comprises body (1), it is characterized in that, and said body (1) side welding cooling water pipe (2), said cooling water pipe (2) is a copper pipe.
2. the copper bar of a kind of IGBT intermediate frequency power supply according to claim 1 is characterized in that, the internal diameter of said cooling water pipe (2) is 12 millimeters.
