Description
Technical field
The present invention relates to a kind of stationary installation, particularly a kind of usefulness is so that the stationary installation that the heater element of heat-conducting plate and circuit board is fitted mutually.
Background technology
Fast development along with present electronics technology, and in order to satisfy the requirement of consumer for data processing speed, the arithmetic speed of computer apparatus internal electronic element must be fast, the volume of adding electronic component is small, cause heat generation density also to increase thereupon, if the untimely discharge of heat, too high temperature will have a strong impact on stability and efficient in the computer operation, also cause the lost of life of electronic component.Therefore, the heat abstractor that removes heat energy that can loose fast promptly becomes one of indispensable outfit of computer apparatus.
The heat abstractor that is constituted with heat-conducting plate collocation lateral flow type fan is an example, for heat-conducting plate firmly and is closely contacted with electronics spare part (for example being CPU, north and south bridge chip), the existing fixed mode is locked on the circuit board or the column of housing for adopting bolt to be arranged in heat-conducting plate, so that heat-conducting plate closely contacts with the electronics spare part.Yet, in the process of locking bolt, excessive or uneven because of the sealed strength of each bolt easily, and the generation circuit board or the problem of heat-conducting plate distortion, or, bolt cause heating radiator to break away from the problem on electronics spare part surface because of getting loose, make heat-conducting plate and electronics spare part surface often can not fit tightly, so that reduce the heat dissipation of heat abstractor.
In order to solve the not good problem of stickiness between heat-conducting plate and the electronics spare part, add a shell fragment with a plurality of perforation in the heat-conducting plate of heat abstractor top, and a plurality of columns are set on circuit board, shell fragment wore perforation in regular turn by a plurality of bolts and was locked on the column, so that the downward strength of pushing and pressing to be provided, fit in electronic component on the circuit board and make shell fragment compress heat-conducting plate.
Compress the mode that heat-conducting plate fits in electronic component with the shell fragment group, though only can solve because the problem that bolt is locked on heat-conducting plate on the circuit board to be produced.Yet, the computer apparatus of different type of machines is because of the restriction of internal wiring (layout), and cause the position of the electronic component of computer apparatus of each type and combined hole and inequality, and the overall height of heat-conducting plate and electronic component is slightly variant, causes existing shell fragment group can't be applicable to the computer apparatus of various types.
Thus, manufacturer must make the shell fragment group that many moneys are complementary, thereby causes the increase of manufacturing cost, and does not meet the requirement that manufacturing industry pursuit at present reduces cost.
Summary of the invention
In view of above problem, the invention provides a kind of stationary installation, improve the defective of prior art with this, so that the shell fragment group applicable to the computer apparatus of various types, avoids producing the problem that manufacturing cost increases.
Stationary installation of the present invention is arranged in the electronic installation, and by a plurality of stationary installations the heater element on one heat-conducting plate and the circuit board is fitted mutually.Heat-conducting plate and circuit board have a plurality of combined holes respectively, and the housing of electronic installation is provided with a plurality of columns.
Stationary installation includes one and inserts and puts part, an elastic component and a fixture.Insert and put part and have an accommodation space, be located in for heat-conducting plate and insert and put in the part, and insert and put the part two ends and be respectively equipped with a perforation.Elastic component is arranged at and inserts and puts in the part, and is in contact with one another with heat-conducting plate one surface, and elastic component is provided with at least one trepanning.Fixture wore perforation, trepanning, and the combined hole of heat-conducting plate, so that insert and put part and elastic component is immobilizated on the heat-conducting plate.Be arranged at the heat-conducting plate that inserts and puts in the part and contact with heater element, and fixture passes the combined hole of circuit board and be fixed in column, so that elastic component is subjected to force compresses and pushes against the heat-conducting plate normality to fit in heater element with another surface.
Useful technique effect of the present invention is: stationary installation can be according to the electronic installation of different type of machines and the corresponding elastic component that adopts coupling, promptly applicable to the electronic installation of various types, elastic component provides a suitable pushing and pressing strength simultaneously, so that heat-conducting plate and heater element normality fit mutually, and has better heat radiating effect.
Above about content of the present invention explanation and the explanation of following embodiment in order to demonstration with explain principle of the present invention, and provide claim protection domain of the present invention further to explain.
