Abstract

The utility model relates to an integral heat emission structure for a capacitor of an electromagnetic oven, an IGBT power tube. The IGBT power tube is connected with a section steel heat emission device. The section steel heat emission device is connected with an integral capacitor and the integral capacitor comprises a metal heat emission shell and a capacitor set formed by simply connecting the capacitors and an extraction electrode by the capacitor set extending. The capacitor bank is fixed on the section steel heat emission device by the metal heat emission shell. The integral heat emission structure for the capacitor, IGBT power tube has advantages of simple and compact structure, small volume, low cost, convenient installation and process and good integral heat emission effect.

Description

The capacitor, the IGBT power tube integral heat sink structure that are used for electromagnetic oven
Technical field
The utility model relates to the electromagentic furnace technology field, especially a kind of capacitor, IGBT power tube integral heat sink structure that is used for electromagnetic oven.
Background technology
Existing electromagnetic oven, can in body of heater, be provided with a plurality of capacitors, IGBT power tube and rectifier bridge etc., they are installed on the circuit board, and a plurality of capacitors on the electromagnetic oven are by being welded on connection in series-parallel composition on the circuit board, because the IGBT power tube can produce bigger heat, therefore when work, generally can on the IGBT power tube, be connected with radiator, so that the heat that the IGBT power tube produces is in time loose.But between the capacitor of above-mentioned electromagnetic oven and the IGBT power tube, still have the following disadvantages: be welded on respectively on the circuit board in mode independently between (1) a plurality of capacitors, constitute series parallel structure, its technology is loaded down with trivial details, brings very big trouble to processing; (2) owing between a plurality of capacitors and IGBT power tube, the rectifier bridge, all be welded on the circuit board, therefore, the use of circuit board is not only given and processing is installed is made troubles, and has increased the manufacturing cost of product to a certain extent; (3) capacitor with disperse, independently form is welded on the circuit board, causes its overall volume bigger, structure is not compact.
The utility model content
The purpose of this utility model is to overcome above-mentioned existing in prior technology deficiency, and provide a kind of simple in structure, compact, volume is little, cost is low, installs easy to processly, and has the capacitor that is used for electromagnetic oven, the IGBT power tube integral heat sink structure of great heat radiation effect.
The utility model purpose is achieved in that
The capacitor, the IGBT power tube integral heat sink structure that are used for electromagnetic oven, the IGBT power tube is connected with Section Bar Heat Sinks, also be connected with the integral type capacitor on the described Section Bar Heat Sinks, the capacitor group that the integral type capacitor includes the heat dissipation metal shell and connected and constitute one by a plurality of capacitors by simplification, the capacitor group is extended extraction electrode, and the capacitor group is fixed on the Section Bar Heat Sinks by the heat dissipation metal shell.
The purpose of this utility model can also adopt following technical measures to solve:
Also be connected with rectifier bridge on the described Section Bar Heat Sinks, so that the heat that Section Bar Heat Sinks can produce rectifier bridge simultaneously looses.
Also be connected with another integral type capacitor on the described Section Bar Heat Sinks.
Electrically connect by book type copper sheet between described IGBT power tube, rectifier bridge and each the integral type capacitor.
Described Section Bar Heat Sinks is the aluminium section bar radiator.
The beneficial effects of the utility model are:
(1) the utility model is used for capacitor, the IGBT power tube integral heat sink structure of electromagnetic oven, system (also can be according to using needs by a plurality of capacitors being made whole one, make two), and in order to help to make the derivation of the capacitor internal heat of whole shape, outside making whole capacitor, have additional the heat dissipation metal shell, and original Section Bar Heat Sinks on the connection electromagnetic oven, but significant effective ground improves the radiating effect of capacitor inside;
(2) because a plurality of capacitors are made integral body, can reduce welding procedure, simplify manufacturing procedure; Moreover, electrically connect by book type copper sheet between IGBT power tube, rectifier bridge and each the integral type capacitor, can exempt the use of circuit board fully, make its overall volume littler, more compact structure, the manufacturing cost of product is lower.
