Description
Technical field
The utility model relates to a kind of heat-exchange device, specifically a kind of plate-fin heat exchanger.
Background technology
At present, have two kinds with air as the primary structure of the aluminium heater of cooling medium: a kind of structure is plate-fin heat exchanger (claiming strip of paper used for sealing formula heat exchanger again), and another kind is a tube-strip heat exchanger.
The fuse of aluminium sheet fin heat exchanger is made up of long strip of paper used for sealing 4, short strip of paper used for sealing 3, dividing plate 5, inner fin 6, outer fin 2, and its core structures sees Fig. 1,2 for details.Described inner fin 6, dividing plate 5, outer fin 2 are alternately stacked, and top and bottom are fixing with baffle plate 1.Inner fin 6 and the long strip of paper used for sealing 4 of its both sides and up and down two dividing plates 5 surround the hot-side channel that forms along its length, outer fin 2 and the short strip of paper used for sealing 3 of its both sides and the heat dissipation channel of two dividing plates, 5 encirclement formation broad ways up and down.The advantage of plate-fin heat exchanger is a compact conformation, the radiating efficiency height, and also mechanical strength is high and new product development cycle is short, and weak point is: 1) part is many, and assembly process is loaded down with trivial details.2) because length strip of paper used for sealing 4,3 all is an aluminium bar, high material consumption, Heavy Weight.3) because hot-side channel is to be surrounded by two long strip of paper used for sealings 4, two dividing plates 5 and inner fin 6 to form, and soldered seam is many, soldering processes difficulty height, present plate-fin heat exchanger all adopts vacuum brazing, the brazing cost height, and can not produce continuously in enormous quantities.The aluminium sheet fin heat exchanger mainly is applicable to the occasion higher to requirement of mechanical strength, as obtaining using quite widely on oil cooler, charge air cooler and the water radiator of engineering machinery, compressor, generating set, at automobile application is in a small amount arranged also.
The fuse of aluminum pipe belt heat exchanger mainly is made up of mainboard 7, outer fin 2, cooling tube 8, and its core structures sees Fig. 3,4 for details, and cooling tube 8 and outer fin 2 alternately are stacked on the described mainboard 7, and top and bottom are provided with baffle plate 1.Than plate-fin heat exchanger characteristics such as simple in structure, that material consumption is little, soldering processes are simple are relatively arranged, and succeeding in developing owing to built-in turbulent sheet heat exchanger, the shortcoming that its radiating efficiency is low has also obtained very big improvement, but still have self unvanquishable shortcoming: 1) its core is thick always than the little 15～20mm of heat exchanger gross thickness, and space availability ratio is low.2) mechanical strength is low.3) mainboard of tube-strip heat exchanger is made needs a lot of secondary mould particular manufacturing crafts, the die cost height, and the construction cycle of new product is long.Aluminum pipe belt heat exchanger is widely used on water radiator that automobile is used, charge air cooler, condenser, oil cooler.
Summary of the invention
To be solved in the utility model is the problems referred to above that existing heat exchanger exists, and a kind of novel plate-fin heat exchanger is provided, and is intended to overcome simultaneously in conjunction with the advantage of traditional plate-fin heat exchanger and aluminum pipe belt heat exchanger both defectives.The technical scheme that addresses the above problem employing is: a kind of plate-fin heat exchanger, comprise baffle plate, short strip of paper used for sealing, outer fin and the cooling tube cooling tube of fin (or be built-in with), it is characterized in that the outer cross section of described cooling tube is rectangle, and constitutes the hot-side channel of length direction; Described outer fin and described cooling tube are alternately stacked, and each outer fin both sides is provided with short strip of paper used for sealing, form the heat dissipation channel of width; The top and the bottom of described heat exchanger are provided with baffle plate.
In order further to strengthen heat dispersion, can also place inner fin in the described cooling tube.
The innovative point of plate-fin heat exchanger of the present utility model is with a cooling tube or a cooling tube that is built-in with fin that is similar to tube-strip heat exchanger two dividing plates of plate-fin, long strip of paper used for sealing, three parts of inner fin (if any) to be merged into a part.Novel plate-fin heat exchanger is that outer cross sectional shape is rectangle with the characteristics of cooling tube, and other cross sectional shape designs according to the instructions for use of heat exchanger.The manufacturing process of novel aluminum plate-fin heat exchanger cooling tube is the same with strip of paper used for sealing all to be to form by hot extrusion.
Compare traditional plate-fin heat exchanger, plate-fin heat exchanger of the present utility model replaces two dividing plates, two long strip of paper used for sealings with a cooling tube, under the prerequisite of the high advantage of the compact conformation, the radiating efficiency that guarantee former plate-fin heat exchanger, eliminated the defective that soldered seam lost efficacy easily between long strip of paper used for sealing of plate-fin heat exchanger and the dividing plate fully, heat exchanger production qualification rate and reliability have been increased, number of parts also significantly reduces, and has reduced the loaded down with trivial details property of assembly process.When plate-fin heat exchanger of the present utility model is applied to air-cooled oil radiator, and the wall thickness of cooling tube two minor faces is 3～5mm; When being applied to absolutely empty charge air cooler and water radiator, the wall thickness of cooling tube two minor faces only is 1.5～3mm, and the long strip of paper used for sealing thickness of general plate-fin heat exchanger is 4.5～7.5mm, so the general plate-fin heat exchanger of the weight ratio of plate-fin heat exchanger of the present utility model is gently many.
Compare tube-strip heat exchanger, plate-fin heat exchanger of the present utility model does not have mainboard, thereby die manufacturing cost is low, new product development cycle short, the mechanical strength height, and under the thickness of fuse and prerequisite that the thickness of heat exchanger equates, space availability ratio improves greatly.
We can say that plate-fin heat exchanger of the present utility model combines the advantage of traditional aluminium sheet fin heat exchanger and aluminum pipe belt heat exchanger, and overcome the shortcoming that they are difficult to overcome self.The pipe structure for cooling of appropriate change plate-fin of the present utility model, the new type of plate fin heat exchanger can be applied to the numerous field of heat exchangers of air as cooling medium, as the water radiator of automobile, engineering machinery and air compressor, air-cooled oil radiator, charger-air cooler, expanded the application of aluminium sheet fin heat exchanger and aluminum pipe belt heat exchanger greatly.
