Description

Stacked chip water-filled radiator

Technical field

The utility model relates to a kind of radiator, relates in particular to a kind of stacked chip water-filled radiator.

Background technology

Along with the integrated level of power electronics industry power model is more and more higher, caloric value is increasing, and the application of the water-cooled type of cooling is also increasingly extensive, and is simultaneously, also more and more higher to the water-filled radiator performance requirement that closely links to each other with heating module.Under identical external environment condition work, the design of different radiator inner flow passages will be to the thermal resistance of radiator, and parameters such as flow resistance cause appreciable impact, so the quality of inner flow passage design has directly determined every performance indications of radiator.

The Chinese patent notification number is: CN1930440A, the day for announcing is: the patent of the present invention on March 14th, 2007 relates to a kind of stacked-plate heat exchanger, particularly be installed in the built-in oil cooler of the tank for coolant of the liquid coolant cooler that is used for automobile, this heat exchanger has some mutually stacked and interconnect, the long slab sheet of brazing filler metal particularly, these plates are made up of two and half plates respectively, and comprise one by medium to be cooled, as oil, cavity along vertical percolation of plate, for the cost that makes the producing zone stacked plate heat exchanger reduces, each half plate has numerous grooves, and they extend to a vertical side on opposite from a vertical side of half plate.The defective of this structure is: the topology layout complexity, manufacturing cost is higher, its runner is made of half plate with numerous grooves, the cooling heat dissipation area is less, make heat exchange insufficient, radiating effect is not good, and this heat exchanger only is suitable for oil as the situation of cooling medium, is not suitable for water-cooled power electronics radiator.

Summary of the invention

The purpose of this utility model be, heat exchange smaller at the contact area that exists in the existing water-cooling type radiator inadequately fully, the dissatisfactory defective of radiating effect and deficiency, now provide a kind of simple in structure, easy to use, contact area is big, the stacked preferably chip water-filled radiator of radiating effect.

For achieving the above object, technical solution of the present utility model is: stacked chip water-filled radiator comprises housing, water inlet and delivery port; The inside of described housing offers the main flow tank, and an end of main flow tank is connected with water inlet, and the other end is connected with delivery port, and in the inside of main flow tank fin is installed and piles up array; Described fin piles up array and is piled up by at least two fin levels and form, and adjacent fin turns over turnback mutually.

Offer the heat radiation crossbeam of at least two inclinations on the described fin, heat radiation is between the crossbeam equidistantly or non-equidistance is arranged in parallel, and the angle between heat radiation crossbeam and the horizontal plane is 10 Du –, 30 degree.

Described fin is stamped to form by rectangular metal sheet.

The beneficial effects of the utility model are:

1, because the inside of the main flow tank in the utility model is equipped with fin and piles up array, fin piles up array and is piled up by at least two fin levels and form, adjacent fin turns over turnback mutually, and offer the heat radiation crossbeam of at least two inclinations on the fin, during use, behind fin superimposed, the area of space that forms between the heat radiation crossbeam constitutes walks aqua region, this is walked aqua region and is the broken line distribution, and run through and crisscross fin and pile up each fin in the array, walk cooling water mobile in the aqua region with between the many beams in plane, the how interplanar mode moving of facade is advanced, and big with radiator contact-making surface linear area, heat exchange is abundant.Therefore not only contact area is bigger for the utility model, and the heat exchange effect is remarkable.

2, owing to mainly piling up array by fin, the main flow tank in the utility model constitutes, not only simple in structure, just with integral body manufacturing and installation, and this structure walking in the aqua region at fixed volume main flow tank, bigger effective water flowing area of section can be provided, whole fluid resistance to cooling water is less, helps strengthening radiating effect, in addition, main flow tank in the utility model is support with multilayer crossbeam array, can improve the bulk strength of radiator.Therefore not only radiating effect is better, less to the whole fluid resistance of cooling water for the utility model, and intensity is higher.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail:

Referring to Fig. 1 to Fig. 5, the stacked chip water-filled radiator of the utility model comprises housing 1, water inlet 2 and delivery port 3; The inside of described housing 1 offers main flow tank 9, and an end of main flow tank 9 is connected with water inlet 2, and the other end is connected with delivery port 3, and in the inside of main flow tank 9 fin is installed and piles up array 7; Described fin piles up array 7 and is piled up by at least two fin 4 levels and form, and adjacent fin 4 turns over turnback mutually.

Offer the heat radiation crossbeam 5 of at least two inclinations on the described fin 4, heat radiation is between the crossbeam 5 equidistantly or non-equidistance is arranged in parallel, and the angle between heat radiation crossbeam 5 and the horizontal plane is 10 Du –, 30 degree.

Described fin 4 by rectangular metal sheet through being stamped to form.

Main flow tank 9 is installed on the housing 1 by screw hole 8, the outline of the fin 4 of main flow tank 9 inside is a rectangular shape, fin 4 is made through punching press by the metal lamella, fin 4 forms the heat radiation crossbeam 5 of a plurality of inclinations after punching press, heat radiation crossbeam 5 width are even, heat radiation crossbeam 5 is equidistantly or non-equidistance is arranged, the heat radiation crossbeam 5 that is equidistant distribution is similar to the comb structure that is certain inclination angle, the area of space that forms between the heat radiation crossbeam 5 has just constituted after fin 4 is superimposed walks aqua region 6, walks the cooling water that can flow in the aqua region 6.

Walk aqua region 6 and be broken line and distribute, and run through and crisscross fin and pile up each fin 4 in the array 7, cooling water can omnibearingly fully contact with fin 4 like this, and the area of generation heat exchange is big, and radiating effect is remarkable.The surface of fin 4 can scribble antirust and other coating.

After cooling water flows in the housing 1 by water inlet 2, piling up array 7 along fin flows near the space between the heat radiation crossbeam 5 on the water inlet 2 one end fin 4, enter away aqua region 6, because heat radiation crossbeam 5 is certain angle of inclination and adjacent fin 4 with respect to the other side's Rotate 180 degree and be formed by stacking, after making that cooling water flows into a segment distance from a fin 4, that passes that superimposed formed passage between two fin 4 enters into adjacent fin 4 walks aqua region 6, and flows forward.In flow process, cooling water flow can constantly flow to walks aqua region 6 between the adjacent fin 4, walk aqua region 6 and be the broken line distribution, and run through and crisscross fin and pile up each fin 4 in the array 7, making cooling water pile up the moving of making a circulation in the array 7 at fin advances, and be flowing forward of stereoscopic multi-layer face, the heat radiation contact area is big, can apply to widely in the radiator runner of various condenses.

Therefore the utility model not only thermocontact area is bigger, and radiating effect is better.
