Abstract

The utility model discloses a radiation fin, which is in a plate type structure and provided with a channel protruding upward. Two end ports of the channel are located on the same side where a connection structure respectively communicated with the two end ports of the channel is arranged. The channel is provided with a plurality of channel recesses including a first channel recess and a second channel recess which are both in a short curved-line structure and a third channel recess arranged between the first channel recess and the second channel recess. A plurality of channel recesses are symmetrically arranged on two sides of the channel. The short curve-line structure channel recesses are adopted and when two radiation fins are combined in use, the attachment overall area of each channel recess is smaller than the attachment overall area of round dot recesses of an existing round dot type radiation fin so that the space of the flowing channel of refrigerants is enlarged indirectly, accordingly the refrigerants can flow more smoothly, and radiation effect is improved.

Description

A kind of fin

Technical field

The utility model belongs to air conditioning for automobiles heat dissipation technology field, is specifically related to a kind of fin.

Background technology

Air conditioning for automobiles is in running, if the air conditioner heat radiator radiating effect is undesirable, the refrigeration of air-conditioning will reduce, and has reduced ride comfort simultaneously, and the refrigeration of radiator is directly by the structures shape of the fin in the radiator.

A kind of fin that uses in the existing air conditioning for automobiles radiator is the point type fin; Point type fin as shown in Figure 1; This point type fin adopts the depression of round point shape; When two point type fin were used in combination, corresponding sunk surface fit together on two fin, had formed the circulation passage of cold-producing medium between depression and the depression.This circle dot mode fin is owing to be provided with more pitting; Cause two fin fitting areas bigger; To such an extent as to the useful space that stays for the circulation passage of cold-producing medium tails off, make the radiating effect variation, thereby influenced the raising of the refrigeration of air-conditioning.

The utility model content

The technical problem that the utility model will solve provides a kind of fin; This fin is when combining use for two one group; The fitting area that caves between two fin reduces; Reserve more space for the circulation passage of cold-producing medium, improved the radiating effect of fin, promptly improved the refrigeration of air conditioning for automobiles.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of fin; This fin is platy structure and has the passage that raises up; The two-port of this passage is positioned at the same side and this side is provided with the syndeton that communicates with the passage two-port respectively; Said passage is provided with some channel recess, and said channel recess comprises first passage depression, second channel depression and the third channel depression between first passage depression and second channel depression that all is funiclar curve shape structure, and several channel recess are arranged symmetrically in the both sides of passage.

The fin of the utility model has adopted the channel recess of funiclar curve shape; When one group of combination of two fin is used; The applying gross area of each round dot depression of the existing circle dot mode fin of applying total area ratio on each channel recess is little; Thereby the space of the circulation passage of cold-producing medium is increased, and cold-producing medium can circulate more swimmingly, improves radiating effect.

Further; Said syndeton comprises a boss and a notch cuttype boss that lays respectively at U-shaped passage two ends and all be the hollow setting; The end face of said notch cuttype boss is provided with first-class through hole and comprises big boss that is positioned at the below and the small boss that is positioned at the top; The end face of said boss is provided with second opening that is complementary with small boss, and is provided with the flanging towards U-shaped passage protrusion direction away from the limit of syndeton, and the end face of this flanging and the upper surface of boss maintain an equal level.When the combination of multi-disc fin was used, an end of fin cooperated with boss through small boss, and the other end passes through the location between the flanging, the stability in the time of can increasing the fin assembling.

Further, the U-shaped passage that said passage is set to take the shape of the letter U, the bending part away from U-shaped mouth one side on the said U-shaped passage is provided with some first guiding depressions, and the junction of said U-shaped passage and syndeton is provided with some second guiding depressions.Through the guide functions of the first guiding depression and the second guiding depression, refrigerated medium is flowed along the direction of U-shaped passage, make that the refrigerated medium circulation is more smooth and easy, improved radiating efficiency.In addition, the U-shaped passage that passage is set to take the shape of the letter U can further be accelerated the flow velocity of cold-producing medium, improves radiating efficiency.

In a word, the fin of the utility model has following beneficial effect:

1, the fin of the utility model has adopted the channel recess of funiclar curve shape; When one group of combination of two fin is used; The applying gross area of each round dot depression of the existing circle dot mode fin of applying total area ratio on each channel recess is little; Thereby the space of the circulation passage of cold-producing medium is increased, and cold-producing medium can circulate more swimmingly, improves radiating effect.

2, the fin of the utility model has adopted the channel recess of funiclar curve shape, has increased the contact area of cold-producing medium and fin, and the heat in the cold-producing medium can be delivered on the fin quickly.

3, the fin of the utility model adopts syndeton to realize the assembling between the polylith fin, through small boss and the cooperation between second opening on the boss, and the stability when having increased by two fin assemblings.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.

Extremely shown in Figure 6 with reference to Fig. 2.A kind of fin that is platy structure has the also passage that raises up on fin, corresponding, and heat sink has the sealing depression 11 around the heat sink edge, and the centre of passage is provided with the isolation depression 13 that begins to extend from syndeton.Preferably, the passage of present embodiment is the U-shaped passage 9 that takes the shape of the letter U, and the U-shaped passage that passage is set to take the shape of the letter U can further be accelerated the flow velocity of cold-producing medium, improves radiating efficiency.The U-shaped mouth place of U-shaped passage 9 is provided with the syndeton that communicates with U-shaped passage both sides respectively; U-shaped passage 9 is provided with some channel recess 12 that are funiclar curve shape structure; Channel recess (12) comprises first passage depression 121, the second channel depression 122 that all is funiclar curve shape structure and is positioned at first passage depression 121 and the third channel depression 123 of second channel depression 122 that several channel recess 12 are arranged symmetrically in the both sides of U-shaped passage 9.The fin of present embodiment has adopted the channel recess 12 of funiclar curve shape; When two fin are one group of combination use; The applying gross area of each round dot depression of the existing circle dot mode fin of applying total area ratio on each channel recess 12 is little, thereby the space of the circulation passage of cold-producing medium is increased, and cold-producing medium can circulate more swimmingly; And the more space of the circulation passage of keeping for cold-producing medium; Channel recess 12 adopts funiclar curve shape structure simultaneously, and this just makes the contact heat-exchanging area of cold-producing medium and fin increase, and improves radiating effect.
