Description

Heat-sink unit

[technical field]

A kind of heat-sink unit, espespecially a kind of heat-sink unit with better thermo-contact plane.

[background technology]

There is in existing electronic equipment CPU and other calculating wafers, and all can produce heat when carrying out computing, therefore need auxiliary the using of heat dissipation element increase its radiating efficiency and reach antipyretic object, the heat dissipation element of the most often use is as heat pipe, temperature-uniforming plate, radiator, the elements such as radiating fin, mainly utilize these elements to increase heat-transfer rate or heat is directed at far-end and carry out far-end heat radiation, or use heat radiation usefulness through increase area of dissipation, general central processing unit mainly contacts heat conduction through with radiator, and radiator increases the effect of area of dissipation for one provides, then heat pipe can be combined with radiator more fast for making its heat-transfer rate, and aperture is offered at the position that radiator contacts with central processing unit or offers groove and heat pipe can directly be exposed to contact with central processing unit heat conduction to transfer heat to the radiator with larger area of dissipation again to dispel the heat, this heat dissipation element be combined with radiator by heat pipe is often used, and this heat dissipation element still has the disappearance that cannot be enhanced, this disappearance is when offering the groove of accommodating heat pipe in this radiator side, through to wear or this heat pipe is fixed in this groove by the mode of vertically placement, but this heat pipe still has the convex position of exposing this radiator and contacting with central processing unit of part, and cause the not good generation thermal chocking of evenness, knownly generally this position to be removed in the mode of Milling Process through by the position of protrusion, and the part protruding the groove of this radiator due to heat pipe is not all phase co-altitude completely, and the tube wall of heat pipe own also has the situation that thickness differs, quite easily excessively cut pin when carrying out Milling Process and thermotube wall is destroyed, heat pipe is made to lose effect.Therefore how to improve known disappearance namely headed by the target of weight.

[utility model content]

For solving the shortcoming of above-mentioned known technology, the main purpose of the utility model, provide a kind of can the heat-sink unit of the smooth precision of plane that contacts with thermal source of heat radiation unit.

The heat-sink unit of the smooth precision of the plane providing a kind of heat radiation unit to contact with thermal source another order of the utility model.

Thering is provided a kind of heat-sink unit for reaching above-mentioned purpose the utility model, comprising: a pedestal, have one first side and one second side, this second side offers the through hole of a groove and this first and second side of plural number connection; One heat pipe, there is a heat absorption district and a conducting region, and this conducting region extends institute's configuration by this heat absorption district at least one end in the direction in this heat absorption district contrary, and this heat pipe is to the position at through hole place should protruding out and be located in these through holes, and trims with first side of this pedestal simultaneously.

Described heat pipe is that a flat hot pipe or D type heat pipe are wherein arbitrary.

The corresponding upper and lower both sides being divided into this pedestal in described first side and this second side.

This pedestal correspondence arranges these protuberance places and directly contacts heat conduction with at least one thermal source.

By the heat-sink unit of the utility model, the heat-sink unit position precision controlling that heat pipe and this heat-radiating substrate contact with thermal source in time assembling that is made up of heat-radiating substrate and heat pipe in the known technology problem such as not easily can be improved.
