Description

Heat abstractor

Technical field

The present invention is relevant with heat abstractor, is meant a kind of easy to assembly and heat abstractor that structure is firm especially.

Background technology

Existing heat abstractor is as shown in Figure 1, this heat abstractor 1 is made up of a plurality of metal sheets 2, the relative both sides of plate 2 are provided with some lugs 3, then being provided with corresponding perforation 4 on the plate 2 supplies the lug 3 of adjacent plate 2 to wear, this lug 3 has one body 5 and two support arms 6 are tiltedly stretched by this body body 5, when making up each plate 2, need earlier this lug 3 to be inserted in the perforation 4 of adjacent plate 2, two support arms 6 that to tiltedly stretch are again evened up, this lug 3 is arranged in this perforation 4, so that each plate 2 is combined, though this structure is firm, right assembling process is consuming time bothersome, increases manufacturing cost on foot.

Summary of the invention

Main purpose of the present invention is to provide a kind of heat abstractor, and it is easy to assembly and structure is firm.

Take off purpose for before reaching, heat abstractor provided by the present invention is to include plural plate, wherein this plate has a body, one the first side wall is by extending under this body one side direction, and one second sidewall extend downwards by this body opposite side, this body has an embedding hole, this first side wall bottom is provided with a clamping sheet, in the embedding hole of inserting another plate, this clamping sheet then has a perforation.

In order to describe structure of the present invention and characteristics place in detail, lift now with next preferred embodiment and cooperate graphic explanation as after.

The specific embodiment

See also Fig. 2 to Fig. 5, the heat abstractor 10 that a preferred embodiment of the present invention provided is to be piled up by plural plate to form, wherein, this plate 20 is made by metal material such as copper, aluminium, this plate 20 includes the body 22 of a rectangle, one the first side wall 30 is extended downwards by these body 22 1 short sides, and one second sidewall 40 is extended downwards by these body 22 other end sides.

This body 22 is provided with four embedding holes 24 and is distributed in pairs near the two short sides, these the first side wall 30 inner edge bottoms are provided with two clamping sheets 32, in the two embedding holes 24 of inserting another plate 20, this clamping sheet 32 has a base portion 33 and is connected with this first side wall 30, one neck 34 is located at this base portion 33 bottoms, and one head 35 be located at this neck 34 bottoms, as shown in Figure 5, the width w1 of this neck 34 is the width w less than this embedding hole 24, the width w2 of this head 35 is then greater than the width w in this embedding hole 24, these clamping sheet 32 heads 35 also have an oval-shaped perforation 36, and these head 35 bottoms have two arc edge 37, make things convenient for this clamping sheet 32 to insert in these embedding holes 24 smoothly.

In addition, this first side wall 30 has more two cramps, 38 inside skew backs and stretches and descend, and in the perforation 36 of inserting another plate 20 clamping sheets 32, and these cramps 38 are perforation 36 root edges that are resisted against these another plate 20 clamping sheets 32 with its bottom.

This second sidewall 40 has two clamping sheets 42, and these clamping sheets 42 have a base portion 43, a neck 44, a head 45, a perforation 46 and one cramp 48 equally, and its structure is identical with the clamping sheet 32 of this first side wall 30, and appearance repeats no more.

Clamping sheet 32 with this first side wall 30 is an example, because the width w2 of these clamping sheet 32 heads 35 is greater than the width w in this embedding hole 24, so when this plate 20 inserts these embedding holes 24 with its clamping sheet 32, must first strain reduce its width, beginning can insert in these embedding holes 24 smoothly, at this moment, the existence of these perforation 36 promptly helps these clamping sheet 32 heads 35 that strain takes place, treat that these clamping sheet 32 heads 35 pass after this embedding hole 24, this head 35 promptly recovers original form, this moment, these clamping sheet 32 necks 34 were arranged in this embedding hole 24, so passed through by four clamping sheets 32,42 are embedded in respectively in these embedding holes 24 and two adjacent plates 20 can be connected together.

Again, because these cramps the 38, the 48th, be inserted in the perforation 36,46 of another plate 20 and be resisted against the root edge of these perforation 36,46, can make the combination of 20 of adjacent plates more firm, and when assembling each plate 20, only need the application of force a little that the clamping sheet 32,42 of one plate 20 is inserted a desired depth in the four embedding holes 24 respectively, can finish the combination of each plate 20, easy to assembly and structure is firm, can effectively improve the disappearance of existing structure, thereby reach purpose of the present invention.

What deserves to be mentioned is, the structure of heat abstractor provided by the present invention can have multiple variation, first and second sidewall can lay respectively at relative two sides of body, also can lay respectively at adjacent two sides of body, the shape of clamping sheet, quantity, the shape of perforation or cramp all can need and change, and the structural change that all these easy full of beard reach all should be the present patent application claim and contains.
