According to the utility model, the capillary groove is processed on the inner wall of the welding port, so that the surface state of the welding position of the welding workpiece is changed, the welding surface roughness of the workpiece is increased, and the wettability of the welding flux on the workpiece is improved, thereby improving the welding performance and the welding quality.
Description
Technical Field
The utility model relates to the field of refrigeration equipment, in particular to the field of welding of a tank body of a refrigeration system.
Background
The refrigeration is that the compressor compresses the gaseous refrigerant into high temperature and high pressure, and sends the refrigerant to the condenser for cooling, the refrigerant is changed into the liquid refrigerant of medium temperature and high pressure after cooling, the refrigerant flows through the expansion valve for throttling and pressure reduction, and is changed into the liquid refrigerant of low temperature and low pressure, the liquid refrigerant absorbs the heat in the air through the evaporator to be vaporized, and then the refrigerant returns to the compressor for continuous compression and circulation, so as to achieve the refrigeration effect. The effectiveness of the refrigeration is therefore closely related to the tightness of the refrigeration system.
In the tank body container, the body is generally made of low-carbon steel, but in order to facilitate welding of air-conditioning manufacturers, a connecting pipe made of copper is usually welded at the installation and connection position of a client, the welding method is brazing, but the brazing position often has the quality problem of leakage due to insufficient filling of the solder.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a structure for welding a tank body in a refrigeration system, which aims to solve the defects caused in the prior art.
A structure for welding a tank body in a refrigeration system is a tank body in the refrigeration system, at least one welding port for connecting with a connecting pipe is arranged on the tank body, and capillary grooves are formed in the inner wall of the welding port.
Preferably, the body is cylindrical in shape and is formed by spinning low-carbon steel, and the body comprises 2 welding ports.
Preferably, the connecting pipe is a copper pipe or a steel pipe.
Preferably, the capillary grooves are distributed on the inner wall of the welding port in a full circle mode.
Preferably, the 2 welding ports are respectively positioned at two axial ends of the body.
Preferably, the refrigeration system tank can be any one of an accumulator, a silencer, a gas-liquid separator and an oil separator.
The utility model has the advantages that: the surface state of the welding position of the welding workpiece is changed, and the capillary groove is processed on the welding surface to increase the roughness of the welding surface of the workpiece, so that the wettability of the welding flux to the workpiece is improved, the welding performance is improved, and the welding quality is improved.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
Referring to fig. 1, in a structure for welding a tank in a refrigeration system, at least one welding port 3 for connecting a connecting pipe 2 is provided on a tank body 1, and a capillary groove 4 is provided on an inner wall of the welding port 3.
In this embodiment, the body 1 is in the shape of a barrel and is formed by spinning low-carbon steel, and includes 2 welding ports, and the welding ports are formed by spinning, so that an end cover is omitted, and an assembly process is simplified.
In this embodiment, the connection pipe 2 is a copper pipe or a steel pipe, which is beneficial to connection with other components.
In the present embodiment, the capillary grooves 4 are distributed all around the inner wall of the welding port 3.
In the present embodiment, 2 welding ports 3 are respectively located at both ends of the body 1 in the axial direction.
As shown in fig. 2, a liquid storage device structure is disclosed, which comprises a device body 1 and a connection pipe 2, wherein 2 welding ports 3 for connecting with the connection pipe 2 are arranged on the device body, the inner wall of the welding port 3 is provided with capillary grooves 4, and the 2 welding ports 3 are respectively located at two axial ends of the device body 1.
The working process and principle of the utility model are as follows: the capillary groove is processed on the inner wall of the welding end interfaces at the two ends of the device body 1 in advance, when in brazing, the welding end interface 3 is sleeved with the connecting pipe 2, and brazing filler metal is placed near the joint gap. When the workpiece and the brazing filler metal are heated to a temperature slightly higher than the melting point of the brazing filler metal, the brazing filler metal is melted (the workpiece is not melted), the brazing filler metal is sucked into and fills the gap by virtue of capillary action, the liquid brazing filler metal and the workpiece metal are mutually diffused and dissolved, and a brazed joint is formed after condensation.
Based on the above, the utility model can process the capillary groove on the welding surface to increase the roughness of the welding surface of the workpiece by changing the surface state of the welding position of the welding workpiece, so that the wettability of the welding flux to the workpiece is improved, thereby improving the welding performance and the welding quality.
It will be appreciated by those skilled in the art that the utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the utility model are intended to be embraced therein.
