Abstract

The utility model discloses a non-welding type radiator, which comprises a bottom plate, a fin group and at least one heat conductive pipe. The upper surface of the bottom plate is smooth, the lower surface of the bottom plate is provided with a groove, and two opposite lateral faces of the bottom plate are provided with notches. The fin group comprises more than one stacked fin, the fins are provided with buckles, and the fin group and the bottom plate are clamped and fixedly connected through the buckles and the notches. Each fin is provided with at least one through hole. The heat conductive tube is in a U shape, one end of the heat conductive tube penetrates into an insert-groove, and the other end of the heat conductive tube is connected in series with the fins through the through holes. The fin group and the bottom plate are in clamping connection, the bottom plate and the heat conductive tube are in blocking connection, and the heat conductive tube and the fins are connected in series so that the bottom plate and the fins do not require electroplated nickel processing, utilization of welding solder paste is avoided, and accordingly the non-welding type radiator is simple in fabrication technology and capable of saving energy and protecting the environment and effectively reducing cost.

Description

A kind of no solder type radiator

Technical field

The utility model relates to radiator, specifically is a kind of no solder type radiator.

Background technology

Radiator is the common passive radiating device that is installed on computer processor, video card, board chip set, Led lamp; It generally includes base plate, fin and heat pipe; By heat conducting mode the heat that above-mentioned electro-heat equipment produces is taken away; Passive heat dissipation characteristics because of radiator need not consumes energy, so radiator has obtained using widely in daily life.However, the existing radiator is the use of bottom plate fins do first nickel plating process, namely the base plate, welded fins filling paste, then heat pipe and the bottom plate, fins assembled, and finally through reflow soldering process so that the parts are joined together to form a complete radiator, causing the radiator complex production process, not saving, environmental damage, and the material used is limited and costly.

The utility model content

The primary and foremost purpose of the utility model is to provide a kind of no solder type radiator, and the scheme of the utility model is:

A kind of no solder type radiator comprises base plate, fins group and at least one heat pipe; Said plate upper surface is level and smooth, and said base plate lower surface is provided with groove, and two opposite flanks of said base plate are provided with groove; Said fins group comprises the fin that is formed by stacking more than, and said fin is provided with buckle, and said fins group and said base plate are affixed through said buckle and said groove clamping; Said fin is provided with at least one through hole; Said heat pipe is " U " shape, and said heat pipe one end is interspersed in the slot; The other end of said heat pipe is connected in series with said fin through said through hole.

Preferably, the section of said groove is the rectangle that a side has opening.

Preferably, said heat pipe and said fin riveted joint.

The no solder type radiator that the utility model scheme provides; Between fins group and the base plate for being clamped and connected; Base plate holds with heat pipe and is connected, and heat pipe is connected in series with fin, thereby base plate, fin need not to do earlier plated nickel and handle; Avoid the use of the welding tin cream, so the no solder type radiator manufacture craft that provides of the utility model is simple, energy-conserving and environment-protective and effectively reduce cost.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

Fig. 1 is the utility model embodiment base arrangement sketch map;

Fig. 2 is the utility model embodiment fin structure sketch map;

Fig. 3 is the utility model example structure sketch map;

Fig. 4 is the structural representation at another visual angle of the utility model embodiment;

Fig. 5 is an A part enlarged diagram among Fig. 4.

Embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Shown in Fig. 1～5, no solder type radiator comprises

Base plate 1, base plate 1 is one has certain thickness rectangular flat, and the upper surface of base plate 1 is level and smooth, and lower surface is provided with at least one groove 11; Two opposite flanks of base plate 1 are respectively equipped with groove 12, and respectively to base plate 1 indent, and groove 12 is parallel with the upper surface of base plate 1 by two sides of base plate 1 for groove 12; Also comprise

Fins group 2, fins group 2 is formed by stacking the fin more than one 21, and fin 21 is tabular; And a side of fin 21 is provided with two ennations; Spacing between two ennations equates with the spacing between the twice groove 12, and two ennations bend to relative direction, forms two buckles 22; Two buckles 22 of fin 21 fasten respectively with the twice groove 12 of base plate 1, make fins group 2 and base plate 1 clamping affixed; Also be provided with on the fin 21 and the identical manhole 23 of base plate 1 groove 11 quantity; And

Heat pipe 3; Heat pipe 3 quantity are identical with the quantity of groove 11; Heat pipe 3 integral body are " U " shape structure that inside has cavity; One end of heat pipe 3 is interspersed in the groove 11 of base plate 1, and the other end of heat pipe 3 is interspersed in the through hole 23 of fin 21, and is further that base plate 1 is fixing with fins group 2 when distributing base plate 1 heat.

As the improvement of the foregoing description scheme, the section of groove 11 is the rectangle that a side has opening, so, an end of heat pipe 3 is interspersed in the groove 11 with fashion of extrusion after, can not produce rotation, makes heat pipe 3 more firm with being connected of base plate 1.

Improvement as the foregoing description scheme; Through hole 23 edges of fin 21 also are provided with flanging; Fin 21 is connected with the riveted joint mode with heat pipe 3; Not only make heat pipe 3 more firm, and can adjust the spacing between each fin 21 in the fins group 22 through the specification of control flanging with being connected of fin 21.

More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
