Abstract
The utility model relates to a coil pipe type cooling device which comprises a coil pipe, and a cooling piece is arranged on the coil pipe. The cooling piece is provided with a cooling sheet and a cooling sleeve pipe, wherein the cooling sheet is provided with a through hole which is communicated with a central hole of the cooling sleeve pipe; the cooling sleeve pipe and the coil pipe are in tight fit. The utility model has the advantages of good cooling effect, small space and convenient installation.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of coiled cooling device.
Background technology
Traditional oil cooler is divided into external cooling device and built-in cooling device, and the external cooling device is arranged on the fuel tank outside, by the structure of pipe middle sleeve, and the general complex structure of this cooling device, volume is bigger; Built-in cooling device adopts in the fuel tank cooling tube is set, what cooling tube adopted coil pipe is the coiled cooling device, feed cooling water in the coil pipe, oil in the fuel tank is cooled off, this mode is simple in structure, do not take up room, but because the heat exchange area of coil pipe is limited, its cooling effect still is not ideal enough.
The utility model content
The purpose of this utility model just provides a kind of by increasing heat exchange area to strengthen the coiled cooling device of cooling effect.
The technical scheme that realizes the utility model purpose is as follows: the utility model comprises coil pipe; Coil pipe is provided with cooling piece, and described cooling piece has cooling fin and cooling collar, and the through hole on the cooling fin and the centre bore of cooling collar connect and same center line, are tight fit between described cooling collar and the coil pipe.
The cooling piece of above-mentioned coiled cooling device is that aluminium sheet is made.
The cooling piece of above-mentioned coiled cooling device is an integral piece, and its cooling collar mechanical stretching forms.
The cooling fin of the cooling piece on the coil pipe that is in the same side of above-mentioned coiled cooling device is connected.
Cooling piece on the coil pipe that is in the same side of above-mentioned coiled cooling device is an integral piece, takes that mechanical stretching has a plurality of cooling collars corresponding with coil pipe on a cooling piece sheet.
Cooling piece on the coil pipe on the utility model has cooling collar, and cooling collar has certain length to increase contact area with coil pipe, has promptly increased heat exchange area, so cooling effect of the present utility model is better.Easy for installation when adopting the integral type cooling piece.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is a partial sectional view of the present utility model.
Fig. 3 is a kind of schematic diagram of cooling piece.
The specific embodiment
See Fig. 1 to Fig. 3, the utility model is the coiled cooling device that is arranged on fuel tank internal, has coil pipe 1, and coil pipe 1 is made up of straight tube and bridge piece, and straight tube is provided with the cooling piece 2 that aluminium sheet is made; Described cooling piece 2 is an integral piece, have cooling fin 21 and cooling collar 22, the centre bore of through hole on the cooling fin 21 and cooling collar 22 connects and same center line, and its cooling fin 21 and cooling collar 22 are formed by mechanical stretching, are tight fit between cooling collar 22 and the coil pipe 1.
The cooling fin 21 that the utility model is in the cooling piece 2 on the coil pipe 1 of the same side is connected.The cooling piece 2 that is in the present embodiment on the coil pipe 1 of the same side is integral piece, takes on a cooling piece sheet 21 mechanical stretching that the corresponding cooling collar 22 of a plurality of and coil pipe 1 is arranged.A plurality of cooling collars 22 are set according to the arrangement of coil pipe 1.Being connected between cooling piece 2 and the coil pipe 1 is to rely on cooling piece 2 and coil pipe 1 tight fit to finish.
The coil pipe of present embodiment is formed by connecting by bend pipe and straight tube, elder generation is not connected the bend pipe of coil pipe with straight tube when assembling, but straight tube is penetrated in the cooling collar 22 of cooling piece 2 of integral piece form, by bridge piece each straight tube is connected then, form the coil pipe of band cooling piece.With respect to the welding of traditional cooling piece and coil pipe, the cooling effect of present embodiment is better, installs more convenient.
