Description

A kind of radiation tube structure with heat

Technical field

The utility model belongs to heat sink technology field, particularly a kind of radiation tube structure with heat.

Background technique

Heat dissipating pipe is the important spare part of automobile radiators.Owing to carrying out heat exchange, so require that heat dissipating pipe has good sealing, corrosion resistance and thermal conductivity in engine cooling water flowing pipe.The heat dissipating pipe that current automobile radiators both at home and abroad adopts, is divided into eyelet pipe, weldless tube and high-frequency tube three kinds by manufacturing process.But application more generally eyelet pipe.The quality of eyelet composite pipe tightness, outside the Pass having with material factor, also has substantial connection with the structure of eyelet and the flowing of solder in eyelet.

Traditional heat dissipating pipe inwall is all smooth structure, in radiation system, time cooling liquid under hyperbaric environment flows through lower header by upper tank, due to the inner wall smooth of heat dissipating pipe, the flow velocity of cooling liquid in heat dissipating pipe is very fast, the waiting time of cooling liquid in heat dissipating pipe is shorter, and radiating efficiency is lower.

Model utility content

The deficiencies in the prior art in view of the above, the purpose of this utility model is to provide a kind of radiation tube structure with heat, to improve radiating efficiency.

For achieving the above object and other relevant objects, technical solutions of the utility model are as follows:

A kind of radiation tube structure with heat, comprise heat dissipating pipe body, heat dissipating pipe body has two panels, surrounds cooling passage, panel inner wall described in one of them is provided with reentrant part, another panel inner wall is provided with the bump corresponding with reentrant part between two panels.

The utility model is the improvement based on eyelet tubular construction, adopt said structure, a panel inner wall protrudes, another panel inner wall is recessed into, and both are corresponding, ensures that the gap of two panels is constant, just change cooling liquid to flow to, slow down flow velocity, cooling liquid currency in heat dissipating pipe is extended, and heat exchange efficiency improves.

As preferably: the female portion and bump all in bar shaped, and are obliquely installed relative to coolant flow direction.

As preferably: the reentrant part on each described panel and bump distribute evenly and at intervals in coolant flow direction.

As preferably: each described panel is provided with many row's reentrant part and bump, the female portion and bump are alternately distributed in rows.

As preferably: the distance L at the female portion and bump distance heat dissipating pipe body two ends is more than or equal to 10mm.

As preferably: the female portion and bump two ends and panel angled transition, and reentrant part and between bump two ends and the vertical line of panel angle be 60 °-80 °.

As preferably: the female portion and bump side and panel angled transition, and reentrant part and between bump side and the vertical line of panel angle be 35 °-55 °.

As preferably: the angle of the female portion and bump and coolant flow direction is 25 °-35 °.

As preferably: the degree of depth of the female portion and bump is 0.25mm-0.45mm.

As preferably: the female portion and bump are extruded by panel, roll extrusion or punching press one-body molded.

As mentioned above, the beneficial effects of the utility model are: in radiation system, time cooling liquid under hyperbaric environment flows through lower header by upper tank, because the concaveconvex structure of heat dissipating pipe designs, to a certain degree change cooling liquid flow through direction, reduce flow velocity, the waiting time of such cooling liquid in heat dissipating pipe is long, and heat energy just can conduct in the middle of air by which better heat-radiation belt.With the situation that the heat dissipating pipe of concaveconvex structure design can effectively avoid heat-radiation belt suspender belt bad in an assembling process, thus enhance productivity.

Embodiment

By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present utility model and effect easily.

As depicted in figs. 1 and 2, a kind of radiation tube structure with heat, comprise heat dissipating pipe body, heat dissipating pipe body has two panels 1,4, cooling passage 5 is surrounded between two panels 1,4, one of them panel 1 (panel 4) inwall is provided with reentrant part, another panel 4 (panel 1) inwall is provided with the bump 3 corresponding with reentrant part 2, the cooperation of reentrant part 2 and bump 3, ensure that the passage gaps of cooling liquid, be equivalent to the circulating direction that the short time changes cooling liquid simultaneously, slow down flow velocity; Make cooling liquid extended residence time in heat dissipating pipe.

Wherein reentrant part 2 and bump 3 are all in bar shaped, are strip bulge or strip groove, and are obliquely installed relative to coolant flow direction, namely tilt relative to the substantially horizontal in figure, to reach the effect slowing down flow velocity preferably.The profile of reentrant part 2 and bump 3 is consistent with direction.

Reentrant part 2 on each panel 1,4 and bump 3 distribute evenly and at intervals in coolant flow direction.

Each panel 1,4 is distributed with along the vertical direction many row's reentrant part 2 and many row's bumps 3, the female portion 2 and bump 3 distribute in rows alternatively up and down, and such as first row is reentrant part 2, and second row is bump 3.

The female portion 2 and bump 3 are more than or equal to 10mm apart from the distance L at heat dissipating pipe body two ends.Heat dissipating pipe stretches out main leaf length is under normal circumstances 4mm (stretching out dimensional range between 3-6mm according to different its of specification), because heat dissipating pipe is the design of band concaveconvex structure, if do not control illustrated dimensions L >=10, the concaveconvex structure of heat dissipating pipe may be caused just through main leaf, cause airtight bad product rejection.

As shown in Figures 3 to 5: for the ease of the circulation of cooling liquid in heat dissipating pipe, avoid blocking etc., reentrant part 2 and bump 3 two ends and panel angled transition, reentrant part 2 and bump 3 side and panel angled transition, and reentrant part 2 and between bump 3 two ends and the vertical line of panel angle b be 60 °-80 °, namely reentrant part 2 and between bump 3 two ends and panel angle be 10 °-20 °.Reentrant part 2 and between bump 3 side and the vertical line of panel angle a be 35 °-55 °; Namely reentrant part 2 and between bump 3 side and panel angle be 35 °-55 °.

The female portion 2 and bump 3 are 25 °-35 ° with the angle c of coolant flow direction.

The depth H of the female portion 2 and bump 3 is 0.25mm-0.45mm, unsuitable too high or too low, in order to avoid affect cooling liquid circulation.

As shown in Figure 6, reentrant part 2 described in this example and bump 3 extruded by panel, roll extrusion or punching press one-body molded.The panel of heat dissipating pipe is generally thinner aluminum component, and one-body molded being convenient to makes, and the concave and convex direction that namely on two panels 1,4, extruding or punching press are formed is consistent.

In radiation system, time cooling liquid under hyperbaric environment flows through lower header by upper tank, because the concaveconvex structure of heat dissipating pipe designs, to a certain degree change cooling liquid flow through direction, reduce flow velocity, the waiting time of such cooling liquid in heat dissipating pipe is long, and heat energy just can conduct in the middle of air by which better heat-radiation belt.With the situation that the heat dissipating pipe of concaveconvex structure design can effectively avoid heat-radiation belt suspender belt bad in an assembling process, thus enhance productivity.

Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
