Abstract

The utility model discloses a kind of cabinet, to improve heat dispersion.The disclosed cabinet of the present embodiment, one-body molded on its at least one face-piece body have an external large fin; Described external large fin also with described cabinet at least one small heat dissipating plate fix, the position of the small heat dissipating plate in described cabinet is corresponding with the position of electronic chip that produces thermal source.

Description

Cabinet

Technical field

The utility model relates to semiconductor heat-dissipating technical field, more particularly, relates to a kind of cabinet.

Background technology

Cabinet is as the part in electronic product accessory, and the Main Function that it rises is to place and fixing each electronic components, plays a support and protective effect; Generally comprise various switches, indicator light etc. on shell, support, panel.

Wherein, in the time that electronic product is used, the components and parts of cabinet inside all can distribute heat, the temperature in cabinet is raise, and then affect the stability of this electronic product.Current case radiation is all to adopt louvre and fan to be set on cabinet to reach radiating effect; Casing is made up of common metallic hard sheet, and radiating effect is not good enough.Meanwhile, some powerful electronic chips of this electronic product are all inside and outside exchanges of carrying out heat by cabinet inside air channel, and radiating effect is also undesirable.

Utility model content

Main purpose of the present utility model is openly a kind of cabinet of excellent heat radiation performance.

For reaching above-mentioned purpose, the disclosed cabinet of the utility model, one-body molded on its at least one face-piece body have an external large fin; Described external large fin also with described cabinet at least one small heat dissipating plate fix, the position of the small heat dissipating plate in described cabinet is corresponding with the position of electronic chip that produces thermal source.

The disclosed cabinet of the utility model, heat can be led casing carry out natural air cooled, though be to entirety or to core electron chip, all there is good heat dispersion.

Brief description of the drawings

Fig. 1 is the external structure schematic diagram of the disclosed a kind of cabinet of the utility model embodiment;

Fig. 2 (a) and Fig. 2 (b) are the internal structure schematic diagram of cabinet in Fig. 1 after taking apart.

Embodiment

Below in conjunction with Figure of description, specific implementation of the present utility model is made a detailed description.Example only, for explaining the utility model, is not intended to limit scope of the present utility model.

Embodiment mono-

The present embodiment discloses a kind of cabinet, and as shown in Figures 1 and 2, one-body molded on the top cover housing of this cabinet have an external large fin 1; External large fin also with cabinet in two small heat dissipating plates 2 fix, the position of this two small heat dissipating plate is with on mainboard, 3 to produce the position of two electronic chips 4 of thermals source corresponding.Optionally, between the each small heat dissipating plate in this cabinet and electronic chip, be connected with chill bar 5; On the other hand, the mode that the small heat dissipating plate in cabinet adopts screw to match with screw with the fixed form of top cover housing.By this, the cabinet mechanism shown in Fig. 2, heat can be led casing carry out natural air cooled, though be to entirety or to core electron chip, all there is good heat dispersion.

As a kind of distortion of the present utility model, above-mentioned small heat dissipating plate and large fin also can be one-body molded, and these conversion, all belong to protection range of the present utility model.

Wherein, as a kind of form of expression of the present utility model, the radiation tooth of the large fin shown in Fig. 2 is uniformly distributed, and on the sidewall of small heat dissipating plate, is distributed with groove.By this, expand the surface area of fin, further improved the heat dispersion of cabinet integral.

Those skilled in the art can expect easily, above-mentioned cabinet can also further be set up the radiating mode of forced air cooling, for example, increase relevant exhausting and/or blowing apparatus, and in the relative side walls of cabinet, offers respectively air inlet and air outlet to form air channel; These conversion, all belong to protection category of the present utility model.

Disclosed is above only several specific embodiment of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection range of the present utility model.

Claims (5)

1. a cabinet, is characterized in that, one-body molded on its at least one face-piece body have an external large fin; Described external large fin also with described cabinet at least one small heat dissipating plate fix, the position of the small heat dissipating plate in described cabinet is corresponding with the position of electronic chip that produces thermal source.

2. cabinet according to claim 1, is characterized in that, between the small heat dissipating plate in described cabinet and described electronic chip, is connected with chill bar.

3. according to the arbitrary described cabinet of claim 1 or 2, it is characterized in that, described large fin is shaped in the top cover of described cabinet.
