Description

Closed fin heat exchanger

Technical field

The utility model relates to a kind of radiator, especially refers to a kind of water-cooled and is provided with the closed fin heat exchanger of radiating fin structure in inside.

Background technology

Existing heat exchanger comprises ventilation type and water-cooled, and wherein ventilation type is most fins of combination on heat sink, and with the area of fin expansion heat sink ingress of air, the heat heat radiation with heat sink exchanges in the air whereby, reaches the cooling effect of heat exchange; Water-cooled then is the working fluid that is marked with cooling effect in heat sink or heat pipe, for example water or refrigerant, flow through heat sink or radiating tube by working fluid, the heat of heat sink or radiating tube is taken out of, reach the heat exchange effect of heat radiation in the mode of contact inwall.

The heat exchange effect of aforementioned existing air-cooled heat exchanger is than the weak effect of water-cooled heat exchanger, but when water-cooled heat exchanger flows owing to working fluid, only the wall with heat sink or radiating tube inboard contacts, the area of contact conduction flow can't effectively increase, and causes the radiating effect of heat exchange further to promote effectively.

The utility model content

Because existing water-cooled heat exchanger provides the working fluid position contacting only to be inboard tube wall, contact area is less and can't promote the efficient of heat exchange effectively.For this reason, the purpose of this utility model is that the runner in heat sink inside is interval with a plurality of radiating fin structures, reaches the effect that promotes the working fluid contact area and can significantly promote heat exchanger effectiveness.

For achieving the above object, the closed fin heat exchanger that the utility model provides comprises:

One heat sink, for keeping flat the plate body of setting, and end face and the bottom surface bigger in area respectively form a radiating surface, respectively form an inlet attack portion and an outlet connection portion in the opposite direction of side face again, each wears an inlet screw and an outlet screw inwardly in the outer face of inlet attack portion and outlet connection portion, form one in the inside of this heat sink and connect this inlet screw and runner that should the outlet screw, for about tortuous circuitous runner form; And

A plurality of radiating fin structures, the direction that difference longshore current road extends, be arranged at intervals in this runner, the both sides of each radiating fin structure extend to the inwall of these runner both sides, and each is connected in top, root edge, and this heat sink pushes up, the inwall of bottom, constructs the flow gap that forms a plurality of intervals and extend in the same way with the direction that this runner extends in each radiating fin.

Further, heat sink described in the utility model is the plate body of rectangle, and described runner is divided into isometric three sections, and in wherein respectively forming a bend portion between the two neighboring sections runner, described a plurality of radiating fin structures are not located at each bend portion.

When the utility model uses, be that the pipeline two that will circulate the working fluid of cooling effect is terminated at inlet screw and outlet screw, and the radiating surface of heat sink bottom surface and bottom surface fitted in need heat exchange heat radiation part, with radiating surface heat is conducted in heat sink, with the working fluid of runner internal flow heat is taken away outwardly by heat sink again, reached the cooling effect of heat exchange whereby.

The beneficial effects of the utility model are, flowing process fluid is except with the inwall of on every side heat sink contacts in the runner, beyond the heat that radiating surface is conducted to heat sink is taken away, can also significantly increase the area of contact heat sink with each radiating fin structure, further promote heat conducting efficient, reach better radiating effect.

The specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done concrete description:

The utility model provides a kind of closed fin heat exchanger, and the preferred embodiment as Fig. 1 to Fig. 3 comprises:

One heat sink 10, for metal plate and be provided with a base plate 11, form a radiating surface 111 for the rectangular metal plate body and in the bottom surface, in the end face of base plate 11 with metal-to-metal adhesive in conjunction with a middle level framework 12, comprise all frames 121, a rib 122 and a back rib 123 before one, wherein all frames 121 are the rectangle framework of metal, and be incorporated into the periphery of base plate 11 end faces with the bottom surface, before rib 122 be horizontal expansion and width bonding jumper less than all frame 121 width, it is incorporated into the centre of all frame 121 right inner face first halfs with right-hand member, be incorporated into the end face of base plate 11 again with the bottom surface, back rib 123 is horizontal expansion and the width bonding jumper less than all frame 121 width, and it is incorporated into the latter half of centre of all frame 121 left inner faces with left end;
