Abstract
The utility model relates to a heat dissipation structure of an induction cooker IGBT module, which comprises an IGBT, a radiator and a control circuit board. The IGBT is attached with the radiator and arranged on the control circuit board. The utility model has the advantages that the IGBT is attached on the radiator. A pin of the IGBT is sleeved with an insulated tube, and the IGBT is fixed at the upper surface of the radiator, thereby being beneficial to the flow of the wind, greatly reducing the temperature of the IGBT and prolonging the service life of a machine. The change of an installation method avoids the disassembly of the radiator, is convenient to the installation and the disassembly of the IGBT and the latter maintenance work and improves the working efficiency.
Description
Technical field
The utility model relates to the mounting structure of electromagnetic oven IGBT module and radiator.
Background technology
Electromagnetic oven is to rely on alternating magnetic field to produce eddy current in the bottom of a pan food is heated, in the course of the work, the generation of alternating magnetic field be inner high power device IGBT do not stop open, turn-off generation, therefore IGBT can produce a large amount of heat, overheated in order to prevent IGBT, generally all radiator is installed, and is used the fan forced heat radiation to IGBT.The electromagnetic oven of prior art is taked such structure: IGBT, the radiator of placing the band pin at circuit board, IGBT is fitted in the lower surface of radiator, promptly be between radiator and the circuit board, can form long and narrow passage between device surface and the wiring board like this, be unfavorable for forming the good ventilation of device, the temperature of device itself can shorten the life-span of device itself than higher; And when relating to the maintenance of IGBT device, maintenance, the radiator of just must dismantling is earlier made troubles.
Summary of the invention
The utility model purpose is to provide a kind of electromagnetic oven IGBT module heat dissipating structure, helps the IGBT heat radiation, improves device lifetime, and is easy to maintenance.
Technical solutions of the utility model are as follows: a kind of electromagnetic oven IGBT module heat dissipating structure, comprise IGBT, radiator, control circuit board, and IGBT and radiator are fitted and are installed on the control circuit board, it is characterized in that described IGBT fits in the upper surface of radiator.
The pin of described IGBT is with insulation tube.
The utlity model has following advantage: IGBT and be fixed on the upper surface of radiator, help flowing of wind, reduce the temperature rise of IGBT itself greatly, reduce more than 5 degree with specific temperature rise, increase the reliability of device, the service life of prolongation machine by test; The radiator of dismantling is avoided in the change of mounting means, has made things convenient for the maintenance work in installation, dismounting and the later stage of IGBT, has improved production efficiency.
The gallery between radiator and the wiring board has been eliminated in the change of heat spreader structures, mounting means, has avoided the harm of insects such as cockroach to IGBT, and it is safer, more reliable that machine is used.
Description of drawings
Be described further below in conjunction with accompanying drawing:
Fig. 1 is traditional electromagnetic oven IGBT module heat dissipating structural representation;
Fig. 2 is the utility model electromagnetic oven IGBT module heat dissipating structural representation;
Among the figure: 1, control circuit board; 2, IGBT; 3, radiator; 4, pin; 5, electromagnetic oven housing
The specific embodiment
Figure 1 shows that traditional electromagnetic oven IGBT module heat dissipating structural representation, IGBT 2 is close to the lower surface that is fixed on radiator 3.Because radiator 3 lower surfaces form a long and narrow passage, IGBT 2 is fitted in the lower surface of radiator 3, promptly is between radiator 3 and the control circuit board 1.
Utility model radiator structure better embodiment shown in Figure 2, be arranged at a kind of electromagnetic oven IGBT module heat dissipating structure of electromagnetic oven housing 5, comprise IGBT2, radiator 3, control circuit board 1, IGBT2 and radiator 3 are fitted and are installed on the control circuit board 1, and described IGBT2 fits in the upper surface of radiator 3; The pin 4 of IGBT2 is with insulation tube, has increased the insulation characterisitic of IGBT 2, uses safer.During installation, earlier radiator 3 is fixed on the pcb board 1, again IGBT 2 is fixed on the radiator 3.
The technical program windage is low, helps flowing of wind, reduces the temperature rise of IGBT itself greatly, reduces more than 5 ℃ by test with specific temperature rise.
Claims (2)
1. the radiator structure of an electromagnetic oven IGBT module comprises IGBT, radiator, control circuit board, and IGBT and radiator are fitted and be installed on the control circuit board, it is characterized in that described IGBT fits in the upper surface of radiator.
2. the radiator structure of electromagnetic oven IGBT module according to claim 1 is characterized in that the pin of described IGBT is with insulation tube.
