Abstract

The utility model relates to an automobile fin plate heat exchanger which is used as an adapter member for an automobile water tank. The automotive fin plate heat exchanger is composed of a right and left water chambers 1, an end seal strip 3, a bimetallic plate 4, a water seal strip 5, foldable fork position fins 6, an overflow pipe 9, etc. The principal points lie in the foldable fork position fins 6 are respectively clamped by both faces of the bimetallic plate 4, and a plane and a water channel are formed by the end seal strip 3, the water seal strip 5 and the foldable fork position fins 6. Besides, a plurality of layers of radiator cores are brazed, and both ends of the radiator core are welded with other component parts of the left and right water chambers. The foldable fork position fins 6 play the role of main body radiation function through a plurality of strips of water channels. The utility model has the advantages of compact structure, light weight, fastness, high heat transferring efficiency, wide adaptability, etc.

Description

Automotive fin plate heat exchanger

It is a kind of radiator that is matched in that the utility model plate type finned heat exchanger is used for auto manufacturing, plays the accessory of thermolysis.

At present, China's industrial economy develop rapidly, auto trade is one of four big pillars of China's industry.Therefore, the demand that is matched in automotive heat exchanger is also increasing, how to improve the radiating effect of heat exchanger, and the common concern that end cost causes auto manufacturing falls in reduced volume.At present, shell and tube and plate type heat exchanger are generally adopted in China's heat exchanger production, and its shortcoming is: cooling pipe adopts oblate and circular brass section; Undulatory red copper radiating gill and cooling pipe alternately, volume is big, Heavy Weight, the cost height, intensity is low, radiating effect is poor.

At the above-mentioned shortcoming that exists, the utility model provides a kind of full aluminium manufacturing, efficient, ultra-thin, the energy-saving plate type finned heat exchanger that collapsible fork-position fin is arranged.

The utility model plate type finned heat exchanger is made up of left and right sides hydroecium 1, coolant inlet pipe 2, end strip of paper used for sealing 3, bimetallic plates 4, water seal bar 5, collapsible fork-position fin 6, adapter plate 7, filler 8, overflow pipe 9, hanging feet 10, coolant outlet pipe 11, dewatering outlet 12, it is characterized in that: bimetallic plates 4 two sides are the collapsible fork-position fin 6 of clamping respectively, there is end strip of paper used for sealing 3 at the fin two ends, form a plane, uniform in the plane 4～6 water seal bars 5, form 3～5 aquaporins, put one deck bimetallic plates on the aquaporin, continuous stratification clamps and the soldering several layers like this, becomes radiator cell; The radiator cell two ends by about (or up and down) hydroecium 1, filler 8 is in hydroecium upper end, a left side (or on), connect overflow pipe 9, coolant inlet pipe 2 front on left hydroecium top, coolant outlet pipe 11 is in the front of right (or down) hydroecium bottom, dewatering outlet 12 is in the back of coolant outlet pipe, hanging feet 10 is welded on by the hydroecium of the left and right sides, and adapter plate 7 is in the radiator cell lower end.As long as add water toward filler 8, when engine starting, drive water pump, form the cooling water expansion tank forced convection, by hundreds of aquaporins heat is delivered to collapsible fork-position fin, play the main body thermolysis by fin.

The utility model plate type finned heat exchanger and shell and tube, plate type heat exchanger relatively have following advantage:

1, compact conformation, intensity height: because this heat exchanger adopts full aluminium manufacturing, weight generally is 1/10 of tubular heat exchanger, radiating fin thin (0.2～0.3mm), every floor height 10mm, aquaporin 2.5mm is because the lamination brazing filler metal, bearing force is big, and the intensity height can bear 100 kilograms per centimeter ²The load of gauge pressure, and collapsible fork-position fin is a heat-transfer surface, is again the support of aquaporin two bimetallic plates, so volume is little, dissipating area is higher than shell and tube more than five times in unit volume, has only 160 meters as shell and tube ²/ rice ³About, and plate type finned heat exchanger generally can reach 2500 meters ²/ rice ³

2, heat transfer efficiency height under with the volume situation, improves more than two times with the ratio heat efficiency of shell and tube.

3, comformability is big, this heat exchanger has heat exchange between 2～9 kinds of media in same equipment, available gas-gas, gas-liquid, interchange of heat between liquid-liquid, this heat exchanger can be used for the situation of following current, adverse current, crossing current and perverse and unreasonable manner stream, and it can use in-273-+500 ℃ range of temperatures.

As Fig. 1, for the utility model plate type finned heat exchanger is matched in structure cutaway view on the radiator.(1:1 cuts open on a left side amplification)

Below in conjunction with Fig. 1 the installation and the use of the utility model plate type finned heat exchanger are described further:

The simple installation of the utility model heat exchanger is mainly used bolt with hanging feet 10 and adapter plate 7, and coolant inlet pipe 2, coolant outlet pipe 11 just are connected with engine engine and can use.Add medium (water) toward filler 8, form the water level convection current, reciprocation cycle on the aquaporin of water seal bar 5 is arranged at pricker by left and right sides hydroecium 1, collapsible fork-position fin 6 conducts heat, and finishes whole heat radiation processes, plays radiating effect.If water level is too high, overflow pipe 9 is over-pressure safety device.
