Abstract
The utility model discloses a condenser soldering transit joint, comprising a left condenser pipe and a right condenser pipe. The calibers of the left condenser pipe and the right condenser pipe are the same. The condenser soldering transit joint is characterized in that the end parts of the left condenser pipe and the right condenser pipe are respectively provided with a copper plating extension pipe, and the opening of one copper plating extension pipe is expanded for matching with the caliber of the other copper plating extension pipe. The condenser soldering transit joint can abolish the existing silver soldering technology, avoiding serial technical problems due to soldering with a zinc plating layer.
Description
Technical field
The utility model belongs to the heat-exchange apparatus field, more specifically, is the condenser in refrigerator, the refrigerator, particularly relates to a kind of condenser soldering transit joint.
Background technology
In electrical equipment such as refrigerator, refrigerator, use refrigerant in associated components and metallic conduit, to circulate, carry out heat exchange and reach refrigeration, condenser promptly is the vitals that is used to cool off refrigerant steam, the general steel pipe that adopts plating zinc on surface or kirsite is to reach purpose anticorrosive, surface aesthetic.
Need in the production process of refrigerator the coating steel pipe of left and right sides condenser is welded, this step welding can't be finished in advance, can only carry out on production line.For this reason, during galvanized pipe, just comprise left condenser pipe and right condenser pipe, enlarging is carried out in one termination wherein handle, but the also reducing of the end of another part connects with silver solder and scaling powder gas welding after two mutual sockets in processing.Because the fusing point of zinc is lower, easy oxidation and can cause the zinc evaporation when gas welding brings many defectives thus, such as, under the effect of zinc oxide, having rosin joint, its hole can cause refrigerant to leak; The welding slag that zinc oxide forms is difficult to clean, and easily becomes source of corrosion, reduces the service life of condenser; Owing to used expensive silver solder, production cost is very high or the like.
For overcoming above-mentioned defective, part refrigerator factory and accessory factory even take the way that peeling is handled is carried out in the end of left and right sides condenser, the zinc coat that is about to its end is removed with machinery, so promptly time-consuming, be difficult to control again, make steel pipe impaired easily, reduce joint quality.
Summary of the invention
To be solved in the utility model is the technical problem that welding brought between coating steel pipe on the condenser, and a kind of condenser soldering transit joint that does not weld between galvanized pipe is provided.
The utility model has adopted following technical scheme: condenser soldering transit joint, comprise left condenser pipe and right condenser pipe, the bore unanimity of left and right sides condenser pipe, it is characterized in that: the end of left and right sides condenser pipe respectively has one section copper-plated extension, wherein one section extension is handled through enlarging, matches with the bore of another section extension.
Further, another section extension is handled through reducing; Two sections extensions are fixed on the condenser pipe with electric resistance welding.
The solderability of copper facing pipe is strong, and the soldering of two sections plating plumbers shed available copper connects, thereby defeasible existing silver soldering technology, has avoided participating in the series of technical that welding causes because of zinc coat; The handling characteristics of condenser is that the inside and outside temperature difference of pipe is quite big, and the unfavorable factor of silver soldering is particularly outstanding, and therefore effect of the present utility model is just more remarkable; Be to connect between extension and the condenser pipe body, can under production line, finish, can when making condenser pipe, finish, therefore can use special equipment to carry out electric resistance welding, and can not produce other problems.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3.The condenser soldering transit joint of prior art comprises left condenser pipe 1 and right condenser pipe 2, and the end of right condenser pipe 2 has enlarging 21, matches with the bore of left condenser pipe 1, with silver brazing 3 both is connected after the socket.
Referring to Fig. 4, Fig. 5, Fig. 6.Condenser soldering transit joint of the present utility model comprises left condenser pipe 1 and right condenser pipe 2, has the extension 4 of copper facing pipe on the left condenser pipe 1, has the extension 5 of copper facing pipe on the right condenser pipe 2, all is connected with the condenser pipe body with electric resistance welding 6; The end of extension 5 has enlarging 51, matches with the bore of extension 4, with copper brazing 7 both is connected after the socket.
Claims (3)
1. condenser soldering transit joint, comprise left condenser pipe and right condenser pipe, the bore unanimity of left and right sides condenser pipe is characterized in that: the end of left and right sides condenser pipe respectively has one section copper-plated extension, wherein one section extension is handled through enlarging, matches with the bore of another section extension.
2. condenser soldering transit joint as claimed in claim 1, it is characterized in that: another section extension is handled through reducing.
