Description

Temperature-uniforming plate

Technical field

The utility model relates to a kind of temperature-uniforming plate, relates in particular on a kind of microprocessor or heat generating component that is arranged on computing machine, can prevent when the out-of-flatness of residing position, and cause working fluid the temperature-uniforming plate of clustering phenomena to occur.

Background technology

Progress along with Information technology and computer industry, the thermal value of electronic package such as central processing unit chip, internal memory etc. is more and more high, and size is more and more little, for this intensive heat effectively being distributed in the outer environment of computer system, keep the following operation of assembly in permissive temperature, usually be attached on the electronic package surface of heating with heat radiator, or, increase its overall radiating efficiency to increase the rotating speed of radiator fan with big base area; So, will produce relevant issues such as noise, weight, cost and system complexity, make that each above-mentioned scheme is not the heat radiation good plan that solves electronic package.

This area is aspect the heat radiation of electronic package at present, utilize characteristics such as high thermal conduction capability that temperature-uniforming plate has, flash heat transfer, high thermoconductivity, in light weight, simple in structure and multi-usage, can transmit a large amount of heat and not consume electric power, therefore be fit to very much the radiating requirements of electronic product; Therefore with temperature-uniforming plate in conjunction with the formed heat abstractor of radiator, become the important topic that solves heat radiation.

Known equalizing plate structure, as shown in Figure 1, it mainly includes a housing 10a, a capillary structure 20a and a supporter 30a, its middle shell 10a is made up of a upper shell 11a and a lower house 12a, and portion has a hollow reservoir within it, is provided with capillary structure 20a and supporter 30a in this hollow reservoir.Capillary structure 20a is coated on the wavy supporter 30a, the outer periphery of capillary structure 20a can be attached on the inwall of housing 10a, again an amount of working fluid is injected the inside of housing 10a, and vacuumize and sealing operation, can be combined into a temperature-uniforming plate.

Yet, above-mentioned known equalizing plate structure, because the bottom of the hollow reservoir of housing 10a is a burnishing surface, when this temperature-uniforming plate is arranged on the top of electronic package, because of the end face of this electronic package or its residing operating environment is not to be one horizontal, make will be towards the position low place of working fluid of housing 10a inside flow, thereby cause the phase change path contraction of fluid and thermal conduction effect not good; And supporter 30a abuts in capillary structure 20a on the inwall of housing 10a in the mode of point or line contact, and the structural strength deficiency that it can support usually makes the downward depressed deformation of end face of capillary structure 20a, thereby significantly reduces the radiating efficiency of this temperature-uniforming plate.

The design people is because the defective that exists in the above-mentioned prior art, rely on the sector experience for many years of being engaged in, at carrying out improved defective, through concentrating on studies and cooperating actual utilization, in line with excelsior spirit, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
