A kind of heat radiation computer host box
Technical field
The utility model belongs to computer hardware field, is specifically related to a kind of heat radiation computer host box.
Background technology
Computer host box mainly comprises cabinet rake and chassis lid two parts; cabinet rake plays the function of fixing its inner each hardware; chassis lid plays covering and does use; its inner each hardware is not exposed; each hardware can be protected; directly expose neat and artistic than each hardware again; owing to producing amount of heat during its inner each hardware effort; so the function of ventilation and heat also will be had; although existing computer host box is provided with air vent and fan on chassis lid; but because its one-piece construction is still too closed, cause radiating effect bad.
Summary of the invention
The purpose of this utility model is too closed in order to solve existing computer host box one-piece construction, causes the problem that radiating effect is bad, and provide a kind of heat radiation computer host box, its technical scheme is as follows:
A kind of heat radiation computer host box, it comprises cabinet rake, left chassis lid, right chassis lid and upper case lid; Described left chassis lid, right chassis lid and be provided with joint pin between upper case lid and cabinet rake, the length of described joint pin is greater than 2 centimetres; Cover at described upper case and be provided with shutter.
The beneficial effects of the utility model are: can fix and protect its internal hardware, make again its inner space and space outerpace open, are beneficial to air circulation, good heat dissipation effect.
accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is the structural representation of joint pin in the utility model.
embodiment:
See figures.1.and.2, a kind of heat radiation computer host box, it comprises cabinet rake 1, left chassis lid 2, right chassis lid 3 and upper case lid 4; Described left chassis lid 2, right chassis lid 3 and be provided with joint pin 5 between upper case lid 4 and cabinet rake 1, the length of described joint pin 5 is greater than 2 centimetres; Described upper case lid 4 is provided with shutter 6.
The center of described joint pin 5 is provided with through hole 5-1, and the correspondence position of left chassis lid 2, right chassis lid 3, upper case lid 4 and cabinet rake 1 is provided with screw, and left chassis lid 2, right chassis lid 3, upper case lid 4 are connected by bolt 7 with joint pin 5, cabinet rake 1.
Preferably, the length of the joint pin 5 be positioned on the downside of described left chassis lid 2 and right chassis lid 3 is greater than joint pin 5 length on the upside of it.
Utility model principle: because chassis lid and cabinet rake 1 leave certain distance, the air circulation that is beneficial to, upper case lid 4 is provided with shutter 6, be beneficial to hot gas upwards to flow, because the length being positioned at the joint pin 5 on the downside of described left chassis lid 2 and right chassis lid 3 is greater than joint pin 5 length on the upside of it, be more conducive to below cold air and enter cabinet inside, ventilate better.
