Fig. 2 is the fractionation structural representation of radiator structure one embodiment of the present utility model;
Fig. 3 is the installation diagram of radiator structure one embodiment of the present utility model.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 2 and the utility model radiator structure one preferred embodiment shown in Figure 3, this radiator structure is applied in the induction cooker circuit board (pcb board) 500, comprise radiator 100, radiator fan 200 and heat-generating electronic elements, most crucial heat-generating electronic elements comprises IGBT300 and bridge heap 400 in the electromagnetic oven, wherein IGBT300 and bridge heap 400 is welded on the pcb board 500, the lower surface of described radiator 100 fits in IGBT300 and bridge heap 400 and fastening by connectors such as screws, and radiator 100 is fixed on the pcb board 500 of electromagnetic oven by screw.
In order to improve radiating effect, can be at the heat sink material of setting example between the contact-making surface of radiator 100 and IGBT300 and between the contact-making surface of radiator 100 and bridge heap 400 such as thermal grease type.Described radiator fan 200 can be fixed in the upper surface of radiator 100, also can be fixed in the side of lower surface or the radiator 100 of radiator 100, and described radiator fan 200 can be for a plurality of.
Further, radiator 100 upper surfaces convex with some fin 110, and radiator fan 100 is fixed on the middle part of radiator upper surface, make being surrounded by fin of radiator fan all around, thereby radiator fan can blow heat radiation to the peripheric surface of radiator, improved radiating efficiency.
Further, in order to reach better radiating effect, the distance at described radiator fan 200 centers and radiator 100 centers should be less than or equal to 5cm.In above-described embodiment, the center of described radiator fan 200 and radiator 100 is for overlapping setting, so that radiator fan 200 blowing heat radiation around the mind-set in radiator 100, to reach best radiating effect.
Further, above-mentioned IGBT300 and bridge heap 400 are arranged at radiator 100 middle parts, and described IGBT300 and bridge heap 400 heats that send transmit to radiator 100 two ends, more are conducive to the diffusion of heat.
Further, described IGBT300 and bridge heap 400 center lines with respect to radiator 100 are crisscross arranged, and also are that their projections on the side of radiator 100 are not overlapping mutually, do not interfere with each other when it is conducted heat to two ends.
The described radiator structure of present embodiment, because radiator fan 200 is directly fixed on the radiator 100, and overlapped with radiator 100, and be arranged side by side unlike radiator in the prior art 100 and radiator fan 200, so radiator fan 200 does not take horizontal space; For longitudinal space, the upper surface of radiator 100 itself has fin 110, and itself there is support plate at the lower surface two ends, therefore can hold radiator fan 200 fully in the situation that does not increase longitudinal size.Thereby dwindled on the whole the size of radiator structure, and then reduced the size of electromagnetic oven.
Moreover after radiator fan 200 is fixed in radiator 100, and the Distance Shortened between radiator 100 and the heat-generating electronic elements, and then it is less to act on their wind-force decay, more is conducive to heat diffusion, has improved radiating efficiency.The radiator fan 200 of present embodiment is fixed in the center of radiator 100, and the wind of radiator fan 200 is diffusion around the mind-set from radiator 100, more is conducive to heat transfer.And IGBT300 and bridge heap 400 is crisscross arranged in the both sides of radiator 100 center lines, and the heat that their produce does not interfere with each other respectively to two ends and the both sides diffusion of radiator 100.
