Description

A kind of electrokinetic cell silicone rubber heating sheet

Technical field

This utility model is related to fever tablet technical field, specially a kind of electrokinetic cell silicone rubber heating sheet.

Background technology

At present, electrokinetic cell is exactly the main energy sources in electric motor car, what electrokinetic cell was often adopted in electric motor car It is battery pack structure, and due to the continuous enhancing of electrokinetic cell endurance, electric motor car is also by simple short distance walking-replacing tool Role has obtained great change, and the electric motor car for using at present needs to make under conditions of various complicated road conditions and difference With, and for electrokinetic cell, harsh climate condition is undoubtedly low temperature environment, this is as electrokinetic cell normal work is to environment There is higher requirement, carrying out discharge and recharge under cryogenic gently can then affect the service behaviour of battery, and serious can also cause electricity Pond internal fault is totally disrupted battery, has had a strong impact on use and the life-span of battery.

Although current electrokinetic cell has self-heating during use, and this belongs to normal battery operation The heat of generation, is much not enough to gimbal border temperature, therefore, in order to ensure the normal work of battery, need to add special Battery firing equipment, conventional heating system there are problems that in various degree the low efficiency of heating surface, length heat time heating time and, Serious meeting is present in battery laminating not closely, affects conduction of heat, and topmost defect is can to carry out in low temperature environment The heating of different degrees of and different-effect, but in normal operation circumstances, firing equipment can have a strong impact on battery again and normally dissipate Heat so that battery temperature is too high, can also have a strong impact on the service life of battery.

Utility model content

For problem above, this utility model provides a kind of electrokinetic cell silicone rubber heating sheet, and the thermal efficiency is high, structure letter Single, reliability is high, because thin and have heat conductivity, radiates unaffected during without working condition, can be with effectively solving background technology Problem.

For achieving the above object, this utility model provides following technical scheme：A kind of electrokinetic cell silicone rubber heating sheet, including Insulated barriers layer and layer of silica gel, the layer of silica gel are coated on inside insulated barriers layer, between the insulated barriers layer and layer of silica gel In sandwich laminated structure, and resistive heater is installed with layer of silica gel, in insulated barriers layer side, outer wall is scribbled and led Hot coating, the heat conducting coating are shaped as rhombus wavy texture, and the insulated barriers layer opposite side also posts heat-insulation layer, and Double faced adhesive tape is also equipped with the outside of heat-insulation layer.

As a kind of preferred technical scheme of this utility model, if the periphery of the insulated barriers layer and layer of silica gel passes through Dry insulation hasp is fixedly installed togather.

Used as a kind of preferred technical scheme of this utility model, the resistive heater is made using nickel alloy, and heats Resistance wire is evenly distributed using intersecting in length and breadth.

Used as a kind of preferred technical scheme of this utility model, the insulated barriers layer and layer of silica gel gross thickness are 0.3- 1.7 millimeters, and insulated barriers layer and layer of silica gel thickness proportion are 1:2.

Compared with prior art, the beneficial effects of the utility model are：The electrokinetic cell silicone rubber heating sheet, using pure resistance Property heating plate, between 0.3-1.7mm, thickness of thin, layer of silica gel cause that the plasticity of fever tablet is strong to general thickness, and size shape can Arbitrarily it is set for according to cell shapes, is taken up room in structure minimum, thickness of thin is lightweight, easy for installation, can be with two-sided gluing Patch is fitted tightly over battery surface, gives battery core heating by conduction of heat, and the thermal efficiency is high, and simple structure, reliability are high, because thin and There is heat conductivity, radiate during without working condition unaffected.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Embodiment：

Fig. 1 and Fig. 2 is referred to, this utility model provides a kind of technical scheme：A kind of electrokinetic cell silicone rubber heating sheet, including Insulated barriers layer 1 and layer of silica gel 2, the layer of silica gel 2 are coated on inside insulated barriers layer 1, the insulated barriers layer 1 and layer of silica gel Be in sandwich laminated structure between 2, and resistive heater 3 be installed with layer of silica gel 2, outside 1 side of insulated barriers layer Wall scribbles heat conducting coating 4, and the heat conducting coating 4 is shaped as rhombus wavy texture, and 1 opposite side of insulated barriers layer is also posted Heat-insulation layer 6, and double faced adhesive tape 5 is also equipped with the outside of heat-insulation layer 6.

Preferably, the periphery of the insulated barriers layer 1 and layer of silica gel 2 is fixedly mounted by several insulation hasps 7 Together, fever tablet internal structure is only fixed on together, prevents from fitting due to internal structure and closely do not cause conduction of heat Inefficiency, or even heat localization can be produced inside fever tablet, there is potential safety hazard；The resistive heater 3 adopts nickel alloy Make, and resistive heater 3 is evenly distributed using intersecting in length and breadth, heating efficiency is high, and the power that itself non-thermal resistance is consumed is low, indulges Traversed by fork arrangement architecture heating is uniform；The insulated barriers layer 1 and 2 gross thickness of layer of silica gel are 0.3-1.7 millimeters, and insulated barriers Layer 1 and 2 thickness proportion of layer of silica gel are 1:2.

The utility model has the advantage of：The electrokinetic cell silicone rubber heating sheet, using pure resistive heating plate, general thickness Between 0.3-1.7mm, thickness of thin, layer of silica gel cause the plasticity of fever tablet by force, and size shape can be arbitrarily according to cell shapes Being set for, taking up room in structure minimum, thickness of thin is lightweight, easy for installation, battery can be fitted tightly over sticking double faced adhesive tape Group surface, gives battery core heating by conduction of heat, and the thermal efficiency is high, and simple structure, reliability are high, because thin and have heat conductivity, without work Radiate during state unaffected.

Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
