Abstract
The utility model discloses a novel tube-fin heat exchanger, which comprises a water inlet chamber, a water outlet chamber and a core. The core comprises an upper composite plate, a lower composite plate, fins and sealing strips, a fin layer consisting of the fins and a sealing strip layer consisting of the sealing strips are fixedly connected between the upper composite plate and the lower composite plate, the fin layer includes two to five parallel long flat tubes which are fixedly connected onto a partition plate, parallelly arranged grooves with arc bottom chamfers are evenly distributed on two sides of each sealing strip, the long flat tubes are placed in a space formed by the corresponding grooves of each two sealing strips, and the fins and the sealing strips are overlapped and brazed integrally. The novel tube-fin heat exchanger has the advantages of high strength and low manufacturing cost.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly relates to pipe heat exchanger.
Background technology
Heat exchanger has been widely used in fields such as aviation, automobile, diesel locomotive, engineering machinery, air compression, air separation, petrochemical industry, air-conditioning, refrigeration at present.As shown in Figure 1, the core body component units of common plate fin heat exchanger has composite plate up and down, left and right sides strip of paper used for sealing and the middle fin among Fig. 1 to constitute, and through the channel direction of change adjacent layer, and not discontinue is folded, after soldering, just constitutes the cross-current type plate-fin heat exchanger.As shown in Figure 2, white arrow representes that part is outer fin channels, and black arrow representes that part is the inner fin passage.Existing tube-strip heat exchanger is applied to the automobile water radiator usually, and the part heat exchanger is also claimed water tank, and such heat exchanger manufacturing process is simple, and cost is low.Radiator is made up of core body, intake chamber, water-supplying chamber.Core body is made up of ratio-frequency welded tube, outer fin, mainboard.Its shortcoming intensity is not high, and needs to make the mainboard mould, is not suitable for small serial production.In order to keep integrally-built stability; Tube-strip heat exchanger needs the flat tube two ends to fix structure with the mainboard of two symmetries; Because the restriction of pipe sizing, mainboard is often thinner, and contact area was less than normal when this had just caused flat tube and plate soldering; Bulk strength is not high, uses for a long time or environment for use tends to take place sealing-off, malformation when comparatively abominable so that radiator damages problem such as can't use.
The utility model content
The utility model has been to overcome the defective of prior art, provides a kind of intensity high, durable novel tube-strip heat exchanger.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Comprise intake chamber, water-supplying chamber, core body; Said core body comprises composite plate, following composite plate, fin and strip of paper used for sealing; Between last composite plate, following composite plate, be connected with the fin layer of fin composition and the strip of paper used for sealing layer that strip of paper used for sealing is formed, said fin layer is the long flat tube that is connected with on the dividing plate side by side, and said strip of paper used for sealing two sides are distributed with the groove of parallel arranged; Said long flat tube places in the space of the corresponding groove composition of two strip of paper used for sealings, and said fin and strip of paper used for sealing stack soldering are an integral body.
Said fin layer forms for the long flat tube of 2-5 root side by side.
Said bottom portion of groove chamfering is a circular arc.
Compared with prior art, the utlity model has following beneficial effect:
1, the groove design of the utility model strip of paper used for sealing can fixedly secure the long flat tube of putting into, thereby has guaranteed the bulk strength of heat exchanger.
2, the utility model strip of paper used for sealing size can change flexibly, adapts to different service conditions.
3, the utility model strip of paper used for sealing can cut use flexibly according to size, and cost significantly reduces.

The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Shown in Fig. 2-6; Novel tube-strip heat exchanger comprises intake chamber, water-supplying chamber, core body, and core body comprises composite plate 1, following composite plate 2, fin 4 and strip of paper used for sealing 3; In last composite plate 1, be connected with the strip of paper used for sealing layer that fin layer that fin 4 forms and strip of paper used for sealing 3 are formed between the composite plate 2 down; Through the channel direction of change adjacent fins layer and strip of paper used for sealing layer, and not discontinue is folded, after soldering, has just constituted novel tube-strip heat exchanger.The fin layer is the long flat tube 6 that is connected with on the dividing plate 7 side by side, and every fin layer forms for the long flat tube of 2-5 root side by side, and the utility model adopts 4 long flat tubes.Every strip of paper used for sealing layer two sides are distributed with the groove 5 of parallel arranged, and groove 5 bottom chamfer are circular arc.Long flat tube 6 places in the space of corresponding groove 5 compositions of two strip of paper used for sealings, and 3 stack solderings are an integral body to fin 4 with strip of paper used for sealing.
The former outer tunnel of above-mentioned strip of paper used for sealing 3 replacements both sides strip of paper used for sealing during the assembling of tube-strip heat exchanger core body; Again long flat tube 6 two ends are placed in these strip of paper used for sealing 3 corresponding groove 5; Add strip of paper used for sealing 3 again above the long flat tube 6, the version that strip of paper used for sealing 3 " was bitten " long flat tube 6 about so stack had just constituted after soldering.
The above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
