Description
Technical field
The utility model is related to a kind of radiator structures, are specifically the IGBT radiator structures in a kind of PTC water heaters.
Background technology
The IGBT of current tradition PTC water heaters is fixed in control chamber body together with PCB mostly, and IGBT is fitted in control
On cavity, using cavity is controlled to radiate with extraneous heat exchange, radiating efficiency is low, can not dispose multiple IGBT, cause PTC
The control strategy of water heater is simple, and IGBT also occupies the arrangement space of PCB, the heat that IGBT is sent in control chamber
It cannot timely distribute, add the temperature of control cavity, be easy to cause the damage of component on pcb board.
Utility model content
The purpose of this utility model is to provide the IGBT radiator structures in a kind of PTC water heaters, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical solution：
A kind of IGBT radiator structures in PTC water heaters, including IGBT, multiple IGBT are installed in IGBT stents
Interior, IGBT stents are fixed under PTC water heaters in bottom case, and are equipped with and are led between bottom case and IGBT stents under PTC water heaters
Thermosphere for heat to be drawn, exchanges heat with the coolant flowed under PTC water heaters in bottom case, the PTC water heaters bottom
Shell is fixedly connected with control cavity, IGBT and IGBT stents is encapsulated in interior.
As further program of the utility model：The heat-conducting layer is insulating heat-conductive silicagel pad.
As the utility model further scheme：Rubber pad is additionally provided between the IGBT stents and control cavity.
Compared with prior art, the beneficial effects of the utility model are：It is radiated using coolant, radiating efficiency is high, can be with
Multiple IGBT are disposed, facilitate the realization of PTC water heater control strategies, moreover it is possible to promote the power of PTC water heaters, install
It is convenient, beneficial to heat dissipation, saved the space of control cavity.
Description of the drawings
Fig. 1 is a kind of structure diagram of the IGBT radiator structures in PTC water heaters.
In figure：Bottom case under 1-PTC water heaters, 2- insulating heat-conductives silicagel pad, 3-IGBT stents, 4-IGBT, 5- rubber pad,
6- controls cavity.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, in the utility model embodiment, the IGBT radiator structures in a kind of PTC water heaters, including
IGBT4, multiple IGBT4 are installed in IGBT stents 3, and IGBT stents 3 are fixed under PTC water heaters in bottom case 1, and
Heat-conducting layer is equipped under PTC water heaters between bottom case 1 and IGBT stents 3, for heat to be drawn, is gone to the bottom with PTC water heaters
The coolant heat exchange of flowing in shell 1, radiates to IGBT4, ensures its normal work, under the PTC water heaters bottom case 1 with
Control cavity 6 is fixedly connected, IGBT4 and IGBT stents is encapsulated in interior.
The heat-conducting layer is insulating heat-conductive silicagel pad 2, has insulation and leads thermal property.
Rubber pad 5 is additionally provided between the IGBT stents 3 and control cavity 6.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The scope of type is indicated by the appended claims rather than the foregoing description, it is intended that will fall containing in the equivalent requirements of the claims
All changes in justice and scope are embraced therein.Any reference numeral in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
Using specification as an entirety, the technical solutions in each embodiment can also be properly combined, forms those skilled in the art
It is appreciated that other embodiment.
