Abstract
The utility model discloses a kind of plate type heat exchanger, comprise end plate (1), take over (2) and plate package (3), described end plate has hole, angle on (1), the bottom of taking over (2) is arranged in hole, angle, end plate (1) covers in plate package (3), described adapter (2) has a ring recess (6) with the outer rim of end plate (1) upper surface contact portion, is provided with cylindric solder (7) in groove (6); Between the contact-making surface of described adapter (2) and end plate (1), be all equipped with foil-shaped brazing material (4); Above-mentioned cylindric solder (7) and foil-shaped brazing material (4) are heated and melt and fill up the gap between adapter (2) and end plate (1) in brazing process, have improved the welding quality of taking over.The utility model has ensured that heat exchanger in use can not occur to cause the situation of taking over fracture or coming off because of weld defect or rosin joint.
Description
Technical field
The utility model relates to field of heat exchangers, especially relates to a kind of plate type heat exchanger.
Background technology
Heat exchanger is the equipment that the part heat of hot fluid is passed to cold fluid.Heat exchanger is the common apparatus of chemical industry, oil, boats and ships, food and other many industrial departments, occupies aborning critical role.Braze welding type plate type heat exchanger, at the condenser as power oil cooler, refrigeration air-conditioner, evaporimeter and economizer etc., is applied more extensive.In end plate and the adapter of existing brazing plate type heat exchanger, as shown in Figure 4, a circle to be opened in the lower end of adapter be less than the annulus of taking over 2 ' overall diameter and be directly inserted in end plate 1 ' when mounted, between adapter 2 ' and end plate 1 ', put into foil-shaped brazing material, before soldering, by expansion or argon arc spot welding, adapter and end plate are fixed, prevent from taking over and come off, then enter vacuum brazing furnace and carry out soldering, by solder be heated melt by take over 1 ' and end plate 2 ' between gap fill up, gap between cooling rear sealing adapter 1 ' and end plate 2 ' also firmly welds together both.Because solder not only will fill up the shared gap 4a of solder self, also to fill up gap 5a, so in welding process, gap 4a there will be filling discontented, cause weld defect or rosin joint, while is due to the mobility constraints of solder, the area of solder again can not be too large, so, weld gap is filled insufficient weld strength that causes heat exchanger to take over and has been subject to impact, in the use procedure of heat exchanger, owing to taking over 2 ' because being given a shock or the impact of moment of torsion, can make to take over 2 ' and rupture or come off, cause heat exchanger to damage.
Utility model content
The utility model is filled insufficient in order to solve current weld gap, the problem that heat exchanger is taken over easy fracture, come off, a kind of plate type heat exchanger is provided, comprise end plate 1, adapter 2 and plate package 3, on described end plate 1, have hole, angle, the bottom of adapter 2 is arranged in hole, angle, and end plate 1 covers in plate package 3, described adapter 2 has a ring recess 6 with the outer rim of end plate 1 upper surface contact portion, is provided with cylindric solder 7 in groove 6; Between described adapter 2 and the contact-making surface of end plate 1, be all equipped with foil-shaped brazing material 4; Above-mentioned cylindric solder 7 and foil-shaped brazing material 4 in brazing process, be heated melt and fill up take over 2 and end plate 1 between gap.
The utility model plate type heat exchanger, the width A of described groove 6 is less than 2mm.
The beneficial effects of the utility model are:
The utility model is owing to having a ring recess in the outer rim of taking over end plate upper surface contact portion, in groove, be provided with cylindric solder, solder is heated to melt and also fully fills up the gap of taking between end plate in brazing process, improve the welding quality of taking over, ensured that heat exchanger in use can not occur to cause the situation of taking over fracture or coming off because of weld defect or rosin joint.
Brief description of the drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is that adapter and end plate, solder are assembled schematic diagram;
Fig. 3 is the schematic diagram after adapter and end plate vacuum brazing;
Fig. 4 is the schematic diagram that existing adapter is connected with end plate.
Detailed description of the invention
Disclosed all features in this description, or step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this description, unless narration especially all can be replaced by other equivalences or the alternative features with similar object.,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
Plate type heat exchanger as shown in Figure 1, comprises end plate 1, adapter 2 and plate package 3, on described end plate 1, has hole, angle, and the bottom of adapter 2 is arranged in hole, angle, and end plate 1 covers in plate package 3.As shown in Figures 2 and 3, described adapter 2 has with the outer rim of end plate 1 upper surface contact portion the groove 6 that a circle width A is less than 2mm, is provided with cylindric solder 7 in groove 6; Between described adapter 2 and the contact-making surface of end plate 1, be all equipped with foil-shaped brazing material 4.Above-mentioned cylindric solder 7 and foil-shaped brazing material 4 in brazing process, be heated melt and fill up take over 2 and end plate 1 between gap, improve the welding quality of taking over, ensured that heat exchanger in use can not occur to cause the situation of taking over fracture or coming off because of weld defect or rosin joint.
The utility model is not limited to aforesaid detailed description of the invention.The utility model expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
Claims (2)
1. a plate type heat exchanger, comprise end plate (1), take over (2) and plate package (3), described end plate has hole, angle on (1), the bottom of taking over (2) is arranged in hole, angle, end plate (1) covers in plate package (3), it is characterized in that: described adapter (2) has a ring recess (6) with the outer rim of end plate (1) upper surface contact portion, is provided with cylindric solder (7) in groove (6); Between the contact-making surface of described adapter (2) and end plate (1), be all equipped with foil-shaped brazing material (4); Above-mentioned cylindric solder (7) and foil-shaped brazing material (4) are heated and melt and fill up the gap between adapter (2) and end plate (1) in brazing process.
