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 The all other embodiment obtained, shall fall within the protection scope of the present invention.

Such as Fig. 1 and Fig. 2, the utility model is implemented to provide a kind of surface insulation type PTC heating plates, including aluminum hull 2, PTC Heating core 1 and connecting line 7.Wherein aluminum hull 2 is main body portion, the side of being provided with logical 3 in aluminum hull 2, and general side logical 3 is located at aluminium The centre position of shell 2, the side that PTC heating cores 1 are packaged in aluminum hull 2 lead in 3, and specifically, PTC heating cores 1 are main work Make component, including PTC chip and electrode slice, wherein PTC chip is heat generating components, and electrode slice is electrically connected with PTC chip, PTC Chip is connect by electrode slice with connecting line 7, and then achievees the purpose that connect with peripheral hardware power supply circuit, and electrode slice is PTC cores The positive and negative anodes of piece, and PTC chip and electrode slice are wrapped in yellow paper, certain Huang paper can not only insulate, and avoid PTC cores Piece and electrode slice are contacted with side logical 3, and yellow paper has certain high temperature resistance, and in addition yellow paper is in package PTC heat generating cores It is also more convenient during body 1, when 1 side of being placed in of PTC heating cores is led in 3, encapsulation PTC hairs can be played by crimping aluminum hull 2 The effect of hot core 1, for connecting line 7, the positive and negative anodes connection of one end and electrode slice, the other end extends to 2 outside of aluminum hull, usually Connecting line 7 is two, and two connecting lines 7 distinguish the positive and negative anodes of counter electrode piece, i.e. the anode of a connecting line 7 and electrode slice connects It connects, another connecting line 7 is connect with the cathode of electrode slice.In the present embodiment, side logical 3 is set to the inside of aluminum hull 2, then aluminum hull 2 lead to 3 positions similar to double-layer structure in counterparty, to this when crimping aluminum hull 2, the deformation position of aluminum hull 2 on surface, so as to To ensure the planarization on 2 surface of aluminum hull, Double-side Heating can be realized.Usual aluminum hull 2 is platy structure, then the aluminum hull 2 after crimping Upper surface and lower surface be plane, specifically, before crimping, the crimping position of aluminum hull 2 has protrusion, when crimping Afterwards, which is generally aligned in the same plane interior with the upper surface of aluminum hull 2 or lower surface, that is, protrusion disappears after crimping, to ensure 2 upper surface of aluminum hull or lower surface after crimping are planar structure, achieve the purpose that Double-side Heating, and it is also relatively more equal to radiate It is even.

Referring to Fig. 2, it is preferable that aluminum hull 2, which leads in positive other side at 3, is provided with electrolysis 4, and logical 3 correspondence electrolysis, 4 side in side is set It is equipped with R angles 5.In the present embodiment, the electrolysis 4 of aluminum hull 2 is the depressed position of aluminum hull 2, which leads to 3 faces with side, and The area side of being slightly less than of electrolysis 4 leads to the area of section of 3 directions, and above-mentioned protrusion is i.e. in the electrolysis 4, by this Structure type, the stress side of being transferred to logical 3 after crimping, and then preferable packaging effect is played, and R angles 5 are set then so that side Logical 3 can adapt to the crimping deformation of aluminum hull 2.Generally, R angles 5 set two, and two R angles 5 are oppositely arranged and are close to electrolysis 4. In a preferred embodiment, the electrolysis 4 of aluminum hull 2 is located in 2 surface area of aluminum hull, i.e., electrolysis 4 is the one of 2 upper surface of aluminum hull Part, i.e., by the top of aluminum hull 2 pushing electrolysis 4, then two above-mentioned R angles 5 are located at the top surface both sides of side logical 3, and lead to 3 along side Length direction extension.

Referring again to Fig. 2, the utility model also provides other embodiment, and aluminum hull 2 is hollow structure, specifically, aluminum hull 2 Region except just logical 3 is provided with along the perforative through-hole 6 of logical 3 length directions in side.In the present embodiment, this 6 structure of through-hole, On the one hand the aluminium usage amount of aluminum hull 2 can be reduced, and on the other hand can reduce the quality of entire heating plate, and also be able to protect Demonstrate,prove the heat dissipation performance of aluminum hull 2.In general, there are two the settings of through-hole 6, above-mentioned side leads to 3 and is located between two through-holes 6.Side logical 3 is located at The centre position of aluminum hull 2, two through-holes 6 are located at the both sides of side logical 3, and certainly in aluminum hull 2, there are two separating parts for setting, pass through two A separating part will be divided into three spaces in aluminum hull 2, lead to 3 positioned at intermediate space counterparty, and the space of both sides is respectively then Two through-holes 6, so that most of position of aluminum hull 2 is hollow structure, heating plate quality minimizes.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
