Abstract

The utility model relates to a radiator connection structure, belonging to the technical field of the heat exchange, which comprises a heat sink, a taper sleeve and a heat conduction pipe. The utility model is characterized in that the taper sleeve is suited on the heat conduction pipe, the inner conical surface of the heat sink is jointed with the outer conical surface of the taper sleeve, the inner conical surface of the heat sink and the outer conical surface of the taper sleeve move relatively under stress, the heat conduction pipe is unclasped by the taper sleeve, simultaneously the heat sink is tightly expanded to form the self-locking fixed connection. The utility model has the advantages that the production cost is low, the whole anticorrosion performance is good, the heat transfer radiation effect is good, and thus the utility model is suitable to be used for indoor or outdoor heat-dissipation devices.

Description

A kind of radiator draw bail

The utility model relates to technical field of heat exchange, specifically a kind of radiator.

At present, set up heat abstractor to producing the thermal source position in various device, the device both at home and abroad, prevent to cause that other part temperatures rising influences service behaviour.Majority need be taked outer radiating mode, promptly by heat pipe the heat in the equipment is delivered on the peripheral hardware fin, and the connecting process tradition of heat pipe and fin is to glued joint or welding.Adhesive technology is with heat-conducting glue two kinds of metals to be bonded together, and the thermal conductivity factor of heat-conducting glue is well below metal, and has grown that heat-conducting glue is aging easily to come off service time, can not fully spread out of heat; The complex process that welding connects, deadly defect is that the back two kinds of materials of welding carry out different surface treatments, almost is to realize, therefore costs an arm and a leg.

The purpose of this utility model provides a kind of radiator that heat pipe and fin is fixedly connected with tapered sleeve.

Scheme of the present utility model is achieved in that by fin, tapered sleeve and heat pipe to be formed.Tapered sleeve adopts the strong metal material of thermal conductivity, and tapered sleeve has groove, and cone angle is chosen rational self-locking angle according to conditions such as frictional force, and the inner conical surface of tapered sleeve outer conical surface and fin centre bore is fitted, and tapered sleeve is enclosed within on the heat pipe.Fin and tapered sleeve be stressed relatively moving in assembling riveting process, tapered sleeve is subjected to the restriction diameter of fin inner conical surface to receive little, hold heat pipe tightly, simultaneously fin be subjected to tapered sleeve to outer expansion force by swelling, the connection between heat pipe and the fin is locked voluntarily by tapered sleeve like this.

The utility model compared with prior art has the following advantages: each part of radiator can carry out surface treatment before assembling and the surface is not destroyed, and has improved overall performance, service life and has prolonged; Because adopt bloated, the pressure mode of tapered sleeve, the contact area between each part is big, heat transfer property is improved; Significantly cost is low in process of production, and the efficient height is easy for installation.Can several pieces fin be installed according to the various needs of product on heat pipe and reach radiating effect.

Fig. 1 is the utility model structure chart;

Fig. 2 is tapered sleeve shape figure of the present utility model;

Fig. 3 is the utility model embodiment.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1, Fig. 2 and Fig. 3 show structure of the present utility model.Tapered sleeve (2) has groove (4), the identical mutual applying of cone angle of tapered sleeve (2) outer conical surface and fin (1) centre bore inner conical surface, tapered sleeve (2) is enclosed within on the heat pipe (3), fin (1) is on tapered sleeve (2), end face adds an outer mechanical compliance conical surface and moves, it is little to force tapered sleeve (2) diameter to be received, and tapered sleeve (2) just can be held tightly heat pipe (3), and tapered sleeve (2) has just been fixed the position at heat pipe (3).Owing to have groove (4) when external force is cancelled on the tapered sleeve (2), fin (1) there is expansive force, formed self-locking between fin (1) and sleeve pipe (2), sleeve pipe (2) and the heat pipe (3) like this and connected.According to actual needs, on heat pipe (3), can load onto array fin (1), reach radiating effect.

Claims

1, a kind of radiator draw bail, form by fin, tapered sleeve and heat pipe, it is characterized in that: tapered sleeve (2) has groove (4) and is enclosed within on the heat pipe (3), fin (1) is enclosed within on the tapered sleeve (2), fin (1) and stressed the relatively moving of tapered sleeve (2), tapered sleeve (2) is held tightly heat pipe (3) by fin (1) inner conical surface restriction diameter receipts I, and fin (1) is subjected to tapered sleeve (2) expansive force swelling simultaneously.
