Abstract

The present invention relates to a liquid cooler which comprises a shell body 6 with a cooling liquid inlet 14 and a cooling liquid outlet 13, cooling pipes 5, a fixed plate 4, a front cover 1 with a cooling liquid inlet 17 and a back cover 10 with a cooling liquid outlet 16, wherein the cooling pipes 5 are fixed to the fixed plate 4, the front cover 1 and the back cover 10 are respectively fixed to the fixed plate 4, a heat absorbing deflector 7 has a flow guiding hole 9, and the heat absorbing deflector 7 is tightly fixed to the cooling pipes 5 and is close to the shell body 6. The liquid cooler has the advantages that the heat absorbing deflector with new design is used, and as a result, the heat absorbing deflector is tightly connected with all the cooling pipes; the heat absorbing deflector connected with all the cooling pipes can be used as both a heat radiator and a deflector, so the circulation process of cooled liquid is lengthened, and the heat radiating area is expanded; and the front cover and the back cover use a plurality of isolation chambers for matching with a plurality of groups of cooling pipes for lengthening the circulation process of cooling liquid, and consequently, the heat exchanging process is lengthened, so that the cooling effect of the cooler is greatly improved. The liquid cooler also has the advantages for saving metal materials, reducing the consumption of the cooling liquid and greatly saving cost.

Description

A kind of cooler

Technical field

The present invention relates to a kind of cooler, particularly relate to a kind of liquid chiller.

Background technology

Existing liquid chiller comprises housing, cooling fluid turnover pipe, adopts light pipe or helix tube to make cooling tube, and the also employing metal fin that has is fixed on the single cooling tube and enlarges area of dissipation, and its shortcoming is that area of dissipation is little.Though such cooler has been carried out a large amount of research and improvement, specifically have: efficiently help the tubular type oil cooler as what Chinese patent 99238497 was used for plant equipment, employing is opened on the screw thread of screw thread cooling tube and has been made some radial grooves, makes its section formative gear or sawtooth colyliform; 97,243,081 1 kinds of transformers of Chinese patent comprise inside and outside tube wall with the aluminium cooling tube of strong oil wind cooling device, are shaped on radiating fin on the outer tube wall, adopt on the inner tubal wall and axially have some uniform cooling baths; Chinese patent 97205934 oil cooler are made up of housing, intake chamber, water-supplying chamber, tube sheet, oil inlet and outlet, deflection plate, heat exchange element, adopt cold-rolled fined tube, and the cold-rolled fined tube expanded joint is to tube sheet, and the labyrinth type circle that is shaped as of deflection plate lacks shape; 00,248,940 1 kinds of helical structure perforated baffles of Chinese patent water-cooled oil cooling machine, comprise the cooler core in housing and the housing, described cooler core comprises evenly distributed cooling water pipe and the deflector that is contained on the water pipe, described deflector is through the helical structure that is formed by connecting by the multi-disc deflector, be processed with the through hole consistent with the water pipe radical on every deflector, all cooling water pipes pass the corresponding through hole on the every deflector in proper order and are fixed between left and right end plate; But above-mentioned these improve heat radiation, the film-cooled heat that still can not effectively increase cooler, so the material cost height, and the cooling fluid waste is big.

Summary of the invention

Technical problem to be solved by this invention provides a kind of cooler, and the heat exchange process that can extend enlarges area of dissipation, improves radiating effect.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

A kind of cooler, comprise protecgulum, bonnet that the housing, cooling tube, fixed head, the band cooling fluid that are cooled band liquid imports and exports are imported and exported, cooling tube is fixed on the fixed head, front and rear covers is separately fixed on the fixed head, it is characterized in that: heat absorption flow deflector band pod apertures, heat absorption flow deflector closely are fixed on the cooling tube and are approaching with housing.

Aforesaid cooler, the heat absorption flow deflector is arranged in many groups, and every group of first pod apertures is one, all the other are two, be symmetrically distributed in two sides by the axis, last group adds a slice single hole heat absorption flow deflector, and the pod apertures being aligned on each sheet heat absorption flow deflector is arranged.Aforesaid cooler, with the position cross arrangement of its pod apertures of heat absorption flow deflector of single pod apertures, promptly pod apertures is shifted one's position in two sides in the described water conservancy diversion heat absorbing sheet group.The heat absorption flow deflector group of this spline structure, the path flow mistake that the liquid that is cooled is arranged by pod apertures in heat absorption flow deflector group can obviously increase the flow process of the liquid that is cooled, and increases area of dissipation.Determine the size of every group of heat absorption flow deflector number, spacing and pod apertures according to the flow of the liquid that is cooled.The shape of pod apertures can change.

Several cooling tubes constitute one group, total array, and the forward and backward lid of cooler is separated by dividing plate respectively, constitutes single path with cooling tube, and cooling fluid is flowed by fixed-direction in pipe.

For fixed head is connected with cooling tube closely, establish groove at fixed head and cooling tube junction, cooling tube makes the cooling tube tube wall embed fixed head by expansion tube process when putting into fixed head like this.

For increasing radiating effect, cooling tube and heat absorption flow deflector all adopt metalwork, are copper, aluminium or aluminium alloy preferably, also can adopt other metal materials of good heat conduction effect.

Compared with prior art, the invention has the advantages that and adopt newly-designed heat absorption flow deflector, it closely is connected with whole cooling tubes, both made radiating element, make conducting element again, increase the circulation process of the liquid that is cooled, enlarged area of dissipation; Front and rear covers adopts a plurality of isolation wards to cooperate many group cooling tubes, increase cooling fluid circulation process, thereby extended heat exchange process, therefore improved the cooling effect of cooler greatly, save metal material, reduce the consumption of cooling fluid, can save cost significantly.
