The utility model content

Fundamental purpose of the present utility model is to provide a kind of heat abstractor, and its assembling is easy and structure is firm.

Take off purpose for before reaching, heat abstractor provided by the utility model is to include plural plate, wherein this plate has a body, one the first side wall is extended by this body one side, and one second sidewall extend by this body opposite side, this the first side wall is provided with a clamping sheet and a perforation, this clamping sheet has an embedding hole, this perforation is to take the shape of the letter U and be adjacent to this body, make these perforation central authorities form a protuberance, this perforation is to supply the clamping sheet of another plate to be installed with, and this protuberance then is arranged in the embedding hole of this another plate, so that plural plate is combined.

Description of drawings

In order to describe structure of the present utility model and characteristics place in detail, lift following two preferred embodiments now and cooperate graphic explanation as after, wherein:

Fig. 1 is the stereographic map of the utility model first preferred embodiment;

Fig. 2 is the partial enlarged drawing of the utility model first preferred embodiment plate;

Fig. 3 is the synoptic diagram of the utility model first preferred embodiment assembling;

Fig. 4 is the partial enlarged drawing of the utility model second preferred embodiment plate;

Fig. 5 is the stereographic map of existing heat abstractor.

Embodiment

See also Fig. 1, Fig. 2, the heat abstractor 10 that the utility model first preferred embodiment is provided is to be combined by plural plate 20, wherein, this plate 20 has the body 22 of a rectangle sheet, one the first side wall 30 is extended by these body 22 1 sides and perpendicular to this body 22, and one second sidewall 40 extend by these body 22 opposite sides and vertical with this body 22, but this plate 20 is made by the material of heat conduction such as copper, aluminium.

This first side wall 30 is provided with two clamping sheets 32 and two perforation 35, this clamping sheet 32 is to be extended downwards by this first side wall 30, these clamping sheet 32 general semicirculars in shape, this clamping sheet 32 has a rectangular embedding hole 33, these clamping sheet 32 both sides are respectively equipped with a recess 34, this perforation 35 is to take the shape of the letter U and be adjacent to this body 22, make these perforation 35 central authorities form a rectangular protuberance 36, this perforation 35 is to supply the clamping sheet 32 of another plate 20 to be installed with, 36 of this protuberances are arranged in the embedding hole 33 of this another plate 20, by this, plural plate 20 can be combined.

This second sidewall 40 also is provided with two clamping sheets 42 and two perforation 45, and this clamping sheet 42 has an embedding hole 43, and these clamping sheet 42 both sides are respectively equipped with a recess 44, and these 45 central authorities of boring a hole then form a protuberance 46, and its structure is identical with this first side wall 30.

When assembling this heat abstractor 10, be as shown in Figure 3, prepare most plates 20 earlier, because the clamping sheet 32 of each plate 20 is to form a predetermined angle α with the first side wall 30, α is 20 ° in present embodiment, and also angle α between second sidewall 40 and the clamping sheet 42, therefore, when a plate 20 abuts against in another plate 20, these clamping sheets 32,42 not can with these protuberances 36,46 interfere, plate 20 can correctly be located, then with these clamping sheets 32,42 punching presses distortion, make these clamping sheets 32,42 are placed in these perforation 35,45 in, make these protuberances 36 simultaneously, 46 embed these embedding holes 33, among 43, wherein, these recesses 34,44 can make these clamping sheets 32,42 distortion takes place easily, constantly carry out in this way, can form heat abstractor 10 of the present utility model in conjunction with the plate 20 of predetermined number.

By this, this heat abstractor 10 not only simple and convenient assembly and structure is firm, really can effectively improve the disappearance of existing structure, thereby reach the purpose of this utility model.

What deserves to be mentioned is, the structure of heat abstractor that the utility model provides can have multiple variation, first, two sidewalls can lay respectively at relative two sides of body, also can lay respectively at adjacent two sides of body, the position and the quantity of the setting of clamping sheet all can change according to need, the clamping sheet, perforation, the shape of embedding hole or protuberance also can change according to need, as shown in Figure 4, it is the heat abstractor 50 that the utility model second preferred embodiment is provided, wherein, the embedding hole 54 of clamping sheet 52 is semicirculars in shape and just can be embedded in wherein for protuberance 56, by so that each plate 58 is combined, the structural change that all these easy full of beard reach all should be the utility model claim and contains.

Claims (6)
