Fig. 3 is the enlarged drawing of part A in Fig. 2.
Specific embodiment
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below With reference to specific embodiment, the utility model is expanded on further.
The utility model heat-conducting plate 100 is mainly used for the heat dissipation of automobile power cell, if Fig. 1 is the utility model embodiment Heat-conducting plate 100 dimensional structure diagram.As shown in Figure 1, the heat-conducting plate 100 of the embodiment of the utility model, including metal Plate 10, insulating coating 20 and soft Heat Conduction Material 30.
Referring to Fig. 1, wherein, metallic plate 10 is used for heat transfer.Metallic plate 10 can be hollow structure, and material is condensed for filling Material, does not limit condensed material specifically, is circulated by condensed material and take away heat, herein so as to play heat dissipation Effect.But metallic plate 10 is not limited only to hollow structure, and it is new to can also be used for this practicality for the cold metallic plate 10 for playing heat dissipation effect to the wind In the heat-conducting plate 100 of type.
Furthermore please continue to refer to Fig. 1,20 even application of insulating coating is covered in 10 surface of metallic plate.The heat-conducting plate 100 is The insulating coating 20 of liquid is sprayed on metallic plate 10 by spraying method, it is fine and close, uniform that one is formed on metallic plate 10 The film layer of insulating coating 20 so that have good bonding force, the film layer of insulating coating 20 between insulating coating 20 and metallic plate 10 Thickness is not limited thereto between 30um-500um.Preferably, insulating coating 20 is silicones, modified epoxy, changes Property acrylic acid or modified polyurethane, insulating coating 20 has stronger proof voltage breakdown capability, can meet proof voltage requirement.
Furthermore before 20 surface of insulating coating is coated on 30 surface of Heat Conduction Material, also need the insulating coating 20 to liquid Cured, the present embodiment is not intended to limit the curing mode of insulating coating 20, can be by the modes such as spontaneously drying or heating to exhausted Edge coating 20 is cured.After insulating coating 20 cures, 20 hardness of insulating coating is high, wear-resisting;And insulating coating 20 and metallic plate 10 have good bonding force, will not generate air void, so that the thermal resistance between metallic plate 10 and insulating coating 20 is small, dissipate Thermal effect is good.
