According to said structure, wherein the hot portion of this resistance is a deformation place of being located at this inner surface of outer cover, by this deformation place to increase the distance between this thermal source and the shell inner surface.
According to said structure, wherein the hot portion of this resistance is a sinking space of being located at this inner surface of outer cover.
According to said structure, wherein the hot portion of this resistance comprises that one is incorporated into the insulating assembly of inner surface of outer cover.
According to said structure, wherein this insulating assembly is plates.
According to said structure, wherein this insulating assembly is attached to this inner surface of outer cover via an adhesion layer.
According to said structure, wherein being provided with one between this thermal source and the hot portion of resistance can be with the conduction diffusion sheet of the even diffusion of heat.
According to said structure, wherein be provided with the heat-conducting piece of a tool high-heat conductive efficency between this thermal source and the conduction diffusion sheet, and this heat-conducting piece contacts with this thermal source, conduction diffusion sheet respectively.
Adopt said structure; The utility model can near the thermal source or heat concentrate to wait the hot portion of resistance of formation one tool thermal resistance between high temperature position and the shell; Use dispersing of suitable this high temperature of obstruct; Avoid causing regional area to produce unusual temperature and raise, and guarantee that whole case surface keeps equal temperature state.

Embodiment
For having more specifically, purpose, effect and characteristic to the utility model understand, existing conjunction with figs. and Reference numeral, and details are as follows:
Like Fig. 3, shown in Figure 4, but the resistance hot type housing cooling structure of knowledge capital utility model first embodiment mainly comprises: thermal source 1, conduction diffusion sheet 2 and hinder hot portion 4 etc. partly; Wherein this thermal source 1 is one can produce the assembly (can be a CPU, power crystal or other similar electronic building brick) of heat; It is arranged on the circuit board 10, and this circuit board 10 then can interior (in the diagram, this clamshell 31 has downward opening according to being arranged at the shell is made up of clamshell 31 and base plate 32 3; 32 of this base plates are covered on the opening of this clamshell 31); And this circuit board 10 has a table side of thermal source 1 towards this base plate 32, in addition is provided with at least one sheet heat-conducting piece 11 with splendid heat conduction efficiency in this thermal source 1, and conduction diffusion sheet 2 is one to have the radiator of splendid heat-conducting effect; It is incorporated on this heat-conducting piece 11; Use the heat of dispersing this thermal source 1, this hinder hot portion 4 can be one have a thermal resistance effect mechanism, it is arranged at the position of this shell 3 (base plate 32) inner surface corresponding to this thermal source 1; In present embodiment; This hinders hot portion 4 is that (for example: sinking space), this deformation place hinders heat conducting effect for increasing the spacing between this thermal source 1 and shell 3 inner surfaces, use to reach to a deformation place of being located at shell 3 (base plate 32) inner surface.
When heat that this thermal source 1 is produced is passed to by heat-conducting piece 11 on the conduction diffusion sheet 2; Wherein there is heat partly and outwards to disperse by the 2 horizontal proliferation conduction of conduction diffusion sheet; Other has the heat that does not partly reach diffusion then can be piled up in the position of this conduction diffusion sheet 2 near thermal source 1 (heat-conducting piece 11); This heat of partly piling up can be dispersed via the mode of radiation or convection current, at this moment, hinders hot portion 4 (being located at the deformation place or the sinking space of shell 3 inner surfaces) by this and hinders control transfer of heat; The position that this shell 3 (base plate 32) is gone up corresponding to this thermal source 1 can't produce higher temperature, makes the situation of these shell 3 surperficial each position temperature distributing disproportionations of unlikely generation.
