Abstract
The utility model discloses a fixing structure for a bearing plate of a PTC (Positive Temperature Coefficient) radiator. The fixing structure comprises a PTC heating body and an aluminous radiating part; at least a fixed groove is arranged in the aluminous radiating part, an opening is formed on one side of the fixed groove, two clamping hooks are respectively arranged on the two sides of the opening, and the PTC heating body is arranged in the fixed groove; and the bearing plate is arranged between the PTC heating body and the clamping hooks, and is pressed on the PTC heating body through the clamping hooks. Since the fixed groove is arranged in the aluminous radiating part, the opening is arranged on one side of the fixed groove, the two clamping hooks are respectively arranged on the two sides of the opening, and the clamping hooks fix the PTC heating body and the bearing plate arranged in the fixed groove, the PTC heating body is pressed tightly. Compared with the prior art, the fixing structure enables the fixed connection of the PTC heating body and the aluminous radiating part to be tighter, and the PTC heating body is prevented from falling off from the aluminous heating part during use.

Technical field
The utility model relates to the radiator of positive temperature coefficient (PTC) heater element, specifically is a kind of PTC radiator shim structure.
Background technology
The PTC radiator is widely used in the multiple appliances such as foot bath, hair style moulding device, hair straightening device and beautifying face steam generator at present.It basically all is to be made up of PTC calandria and the metallic aluminium heat sink with hollow structure; The aluminium heat sink comprises two face-to-face and substantially parallel inner surfaces; The PTC calandria contacts between these two inner surfaces and with it; The PTC calandria is connected with power supply through power line, generates heat the heat transferred of being sent by the PTC calandria gas apparatus use of supplying power behind the aluminium heat sink during energising.
The PTC radiator of this structure is owing to be fixedly connected defective tightness between PTC calandria and the aluminium heat sink, and in use, the PTC calandria is easy to from the aluminium heat sink, come off, thereby causes product failure.
The utility model content
In view of above problem, the purpose of the utility model is to provide a kind of PTC radiator shim structure, so that closely fixing between PTC calandria and the aluminium heat sink, avoid the PTC calandria from the aluminium heat sink, to come off.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of PTC radiator shim structure; Comprise PTC calandria and aluminium heat sink, be provided with at least one holddown groove in the said aluminium heat sink, said holddown groove one side is provided with opening; These opening both sides respectively are provided with a grab; Be fixed with the PTC calandria in the holddown groove, be provided with backing plate between said PTC calandria and the grab, this backing plate is pressed together on the PTC calandria through grab.
Wherein said grab is to the holddown groove tilt.
At least be provided with a holddown groove in the aluminium heat sink of the utility model; One side of this holddown groove is provided with opening; The opening both sides respectively are provided with a grab, will be arranged in the PTC calandria and the shim of holddown groove through this grab, thereby the PTC calandria is compressed.Compared with prior art, the utility model make between PTC calandria and the aluminium heat sink be fixedly connected tightr, in use, the problem of having avoided the PTC calandria from the aluminium heat sink, to come off.

Embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
The utility model provides a kind of PTC radiator shim structure, comprises PTC calandria and aluminium heat sink, in the aluminium heat sink, is provided with a holddown groove at least, and the PTC calandria is fixedly mounted in this holddown groove.
The utility model preferred embodiment one
Like Fig. 1, shown in Figure 2, Fig. 1 is the utility model preferred embodiment one PTC radiator side sectional structure sketch map; Fig. 2 is the utility model preferred embodiment one PTC radiator cross section sectional structure sketch map.Be provided with a holddown groove 103 in the aluminium heat sink 101, the top of this holddown groove 103 is provided with opening, respectively is provided with a grab 102 in the both sides of opening, and this grab 102 is an integral body with whole aluminium heat sink 101.
The utility model preferred embodiment two
Like Fig. 3, shown in Figure 4, Fig. 3 is the utility model preferred embodiment two PTC radiator side sectional structure sketch mapes; Fig. 4 is the utility model preferred embodiment two PTC radiator cross section sectional structure sketch mapes.Be provided with a holddown groove 203 in the aluminium heat sink 201, the top of this holddown groove 203 is provided with opening, respectively is provided with a grab 202 in the both sides of opening, and this grab 202 is an integral body with whole aluminium heat sink 201.
PTC calandria 205 is arranged in holddown groove 203, is provided with backing plate 204 above it, and these backing plate 204 sizes are identical with PTC calandria 205, and the left and right sides of backing plate 204 upper surfaces is to compress through grab 202, and the bottom surface then is to contact with PTC calandria 205.
Through to the grab 202 that is arranged in both sides, opening top along the punching press of Fig. 4 direction of arrow, make grab 202 that deformation take place, be closely pressed together on the backing plate 204 of below, thereby make whole PTC calandria 205 compacted, can effectively avoid it to come off.
The utility model preferred embodiment three
Like Fig. 5, shown in Figure 6, Fig. 5 is the utility model preferred embodiment three PTC radiator side sectional structure sketch mapes; Fig. 6 is the utility model preferred embodiment three PTC radiator side sectional structure sketch mapes.Aluminium heat sink 301 is a tubular; The inner corresponding both sides of this pipe respectively are provided with a holddown groove 303; Described holddown groove 303 1 sides are provided with opening, and two side positions of this opening respectively are provided with a grab 302, and described grab 302, aluminium heat sink 301 are an integral body.
