Accompanying drawing explanation
Fig. 1 is the first application schematic diagram of the present invention；
Fig. 2 is the second application schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, 2；A kind of heat pipe heat radiation type height IP degree of protection bin of built-in small-power heater element, its bag
Containing: high IP degree of protection shell 1, arrange described small-power heater element 2 inside it, small-power heater element 2 is PLC's
The small-power heater element such as CPU, power module；Heat pipe 3, its one end is positioned at high IP degree of protection shell 1, and is led by viscosity
Hot glue 4 connects the small-power heater element 2 air plankton with eliminating joint place, and its other end embeds high IP degree of protection shell 1
Wallboard in, utilize outside large space air to cool down by wallboard, to reduce the running temperature of heater element, improve it and run shape
State, simultaneously because be directly embedded in wallboard so that high IP degree of protection shell 1 surrounding wallboard can also serve as the heat radiation of heat pipe
Fin.Described heater element 2 is usually mounted on the installing plate in distribution box cabinet, in practical operation, and optional heater element
Fit in relatively big and that temperature the is higher face of heat removal surface area.
Described heat pipe 3 one end connects the little merit in high IP degree of protection shell 1 as evaporation side by viscosity heat-conducting glue 4
Rate heater element 2, its other end embeds in the wallboard of high IP degree of protection shell 1 as condensation side, and wallboard referred herein can
To be top board or each wallboard of surrounding of high IP degree of protection shell.It should be noted that, the evaporation of medium in heat pipe 3, condensation spy
Property need to adapt with the operating temperature range of heater element 2.
In one embodiment of the invention, described heat pipe 3 other end is top board or the side embedding high IP degree of protection shell 1
In wall, described top board is in tilted layout, and has certain inclination angle, and in being beneficial to heat pipe 2, cooling medium is back to evaporation side.
Described heat pipe 3 uses and forms through the one compacting of antiseptic copper shell, it is to avoid welds or reduces solder joint to subtract
