Description

The heat radiation module

Technical field

The utility model is relevant with heat dissipation technology, is meant that especially a kind of heat pipe cooperates the heat radiation module of forming with high heat dissipation efficiency with fin.

Background technology

Fig. 5 is to shown in Figure 6, be to be an existing heat abstractor 70, mainly form by two relative fin 71 and top fin 73, form with four groups of heat pipes 75 that are the side U-shaped, the pedestal 72 of these fin 71 has the groove 721 that cutting is straight shape, and this two relative fin 71 is to splice mutually, and make these fins 722 be relative shape, these heat pipes 75 are to be placed in these grooves 721, use to make heat energy can be conducted to the fin 71 of top fast by the fin 71 of bottom; Side in these fin 71 is provided with a fan 77, is used for quickening the radiating effect of these fin 71.

Aforesaid existing heat abstractor 70, it still has the space of improvement on structure and radiating efficiency:

One, the fin 722 of these two relative fin 71 does not contact with each other or connects, though there is heat pipe 75 to transfer heat energy to the respectively pedestal 72 of this fin 71, yet, heat energy on the fin 722 below being positioned at but can't directly be passed to the fin 722 of top, cause the higher non-uniform phenomenon of local temperature, radiating effect is restricted.

Two, this two relative fin 71 is to pile up mutually, and in order to make the structural strength of piling up enough strong, it needs thicker fin 722 or abutment wall to pile up each other, and on the identical pedestal 72 of area, the thickness of fin 722 is thicker, the quantity that can be provided with is promptly fewer, so its area of dissipation is less, and radiating effect also is restricted.

Three, heat pipe 75 only with the tube wall of half with between fin 71 contacts, its heat-conducting effect is relatively poor.

The utility model content

Main purpose of the present utility model is promptly providing a kind of heat radiation module, and it has the radiating effect better than prior art.

For achieving the above object, the technical solution of the utility model is:

A kind of heat radiation module includes:

Two substrates are heat-conductings, have at least one groove of wearing;

Plurality of fins is a heat-conducting, is arranged between this two substrate;

At least one heat pipe is with two sections grooves of wearing that are inserted in respectively on this two substrate about it; The body portion of this heat pipe is positioned at these fin outsides;

One fan is arranged at these fin outsides.

Described heat radiation module, wherein: these heat pipes are to be three groups, respectively this substrate is to be provided with three to wear groove, these heat pipes be bending take the shape of the letter U and with about it two sections plant these respectively and wear groove.

Described heat radiation module, wherein: this fan is the edge that is positioned at these fins, the body portion of these heat pipes is sides that are positioned at these fins.

Described heat radiation module, wherein: this fan is an edge that is positioned at these fins, the body portion of these heat pipes is another edges that are positioned at these fins.

Described heat radiation module, wherein: the body portion of this fan and these heat pipes is the same edges that are positioned at these fins.

Embodiment

In order to describe structure of the present utility model and characteristics place in detail, below lift three preferred embodiments and cooperate graphic explanation as back:

See also Fig. 1 to Fig. 2, a kind of heat radiation module 10 that the utility model first preferred embodiment is provided mainly is made up of two substrates 11, plurality of fins 21, at least one heat pipe 31 and a fan 41, wherein:

This two substrate 11 is metal heat-conducting materials such as aluminium, copper, has three in the present embodiment to wear groove 12;

These fins 21 are arranged between this two substrate 11 parallel each other the and preset distance of being separated by;

Three heat pipes 31, respectively bending take the shape of the letter U and with about it two sections plant these respectively and wear groove 12, the body portion of these heat pipes 31 is positioned at these fin 21 outsides, is that example only is explanation with three heat pipes in the present embodiment, be not quantity with heat pipe be restriction important document of the present utility model;

This fan 41 is arranged at these fin 21 outsides;

This fan 41 is edges that are positioned at these fins 21, and the body portion of these heat pipes 31 is sides that are positioned at these fins 21.

Please consult Fig. 1 again, the utility model is when using, be the heat energy on the lower substrate 11 (being as the criterion with Fig. 1 direction) to be delivered to upper substrate 11 fast by this heat pipe 31, in addition, by these fins 21 is to be connected in this two substrate 11 up and down, the heat energy of this two substrate 11 can be fast to the conduction of fin 21 central authorities, by this fan 41 blow to see through air heat energy outwards taken out of, by this kind framework, heat radiation module 10 provided by the utility model is to dispel the heat in the mode of approaching whole group soaking, and its radiating effect is splendid.

Please consult Fig. 3 again, a kind of heat radiation module 10 ' that the utility model second preferred embodiment is provided is taken off embodiment before mainly generally being same as, and difference is:

This fan 41 ' is an edge that is positioned at these fins 21 ', and the body portion of these heat pipes 31 ' is another edge that is positioned at these fins 21 ';

Before generally being same as, takes off the usage operation of this second embodiment the real example of dragging, do not repeat them here, and present embodiment still has an extra effect, promptly, the air that this fan 41 ' blew is except taking away the heat energy by using between these fins 21 ', also, also can take away the heat energy on this heat pipe 31 ' by this, reach better radiating effect by the tube wall of these heat pipes 31 '.

Please consult Fig. 4 again, a kind of heat radiation module 10 that the utility model the 3rd preferred embodiment is provided ", take off embodiment before mainly generally being same as, difference is:

This fan 41 " and these heat pipes 31 " body portion be positioned at these fins 21 " same edge;

Before generally being same as, the usage operation of this 3rd embodiment takes off embodiment, do not give unnecessary details at this, and this fan 41 in the present embodiment " and these heat pipes 31 " body portion between distance extremely near, this fan 41 " air that blown can directly take away heat pipe 31 " on heat energy, also can take away simultaneously these fins 21 " on heat energy, reach better radiating effect than prior art.

Via above-mentioned structure, the utility model can produce following advantage:

One, excellent in heat dissipation effect: fin 21 of the present utility model is to be connected in up and down this two substrate 11, The heat energy of this substrate 11 can directly be passed to another substrate 11 via fin 21, and this practicality is new The fin 21 of type is to be that full wafer connects, there is no interrupted, than prior art with two fin stacking and fin Sheet does not join or the dialysis state, the utlity model has bigger area of dissipation, radiating effect Better.

Two, structural strength is good: the utility model is to be connected in up and down this two substrate with plurality of fins 21 11, be not to be to form so that two fin are stacked such as prior art, upper and lower base plate 11 of the present utility model And 21 of these fins can not slide, and its overall structure is good, can adopt thinner fin 21, in phase Can increase the sheet number of fin 21 in the substrate surface area together, that is area of dissipation also strengthens, same Increased radiating effect.
