Description

Technical Field

[0001] The utility model belongs to a tube structure for an air-conditioning evaporator, in particular to an air-conditioning evaporator copper tube component which is convenient for connecting fins. Background Art

[0002] The evaporator is one of the important components of the air conditioner. At present, the evaporator input pipe assembly used in the air conditioner uses an output pipe with a larger diameter, which is connected to the condenser through the output pipe. The output refrigerant enters the condenser through a single channel, which affects the refrigeration efficiency. In order to improve the transmission efficiency of the refrigerant and achieve heat exchange as soon as possible to achieve the refrigeration effect, some existing output pipes are divided into two. For example, the application number 201822095536.2 discloses an evaporator machine air conditioning equipment. It can be seen from the attached figure of its specification that an output pipe is connected to the evaporator body, and the refrigerant is output through the output pipe. After the output, it can only be connected to the external structure with a single interface, which makes the heat exchange area of ​​the refrigerant relatively small, affecting the refrigeration effect of the air conditioning equipment.

[0005] The beneficial effect of the utility model is that by providing an inclined tube and by setting the directions of the first output tube and the second output tube, it is convenient to set multiple output tubes on the inclined tube, and by bending the first output tube to one end of the fourth output tube, sufficient space is freed between the output end of the first output tube and the third bending portion, thereby facilitating the setting of the second output tube and facilitating the connection of the first output tube and the second output tube with the external structure, thereby realizing the setting of multiple output tubes, facilitating the refrigerant input at the input tube to be diverted and output via the four output tubes, facilitating the refrigerant to be quickly dispersed, thereby facilitating improving the refrigeration efficiency.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1 to Figure 5 The air conditioner evaporator copper tube assembly conveniently connected to the fin comprises an input tube 1, a tube protection spring 2, a first output tube 3, a second output tube 4, a third output tube 5 and a fourth output tube 6. The input tube 1 is provided with a first bending portion 11, a second bending portion 12 and a third bending portion 13. The tube protection spring 2 is sleeved on the outside of the input tube 1 and is located outside the first bending portion 11, the second bending portion 12 and the third bending portion 13. An inclined tube 14 is provided at one end of the input tube 1, and the inclined tube 14 is located on one side of the third bending portion 13. The first output tube 3, the second output tube 4 and the third output tube 5 are all connected to the inclined tube 14 in sequence. The fourth output tube 6 is connected to one end of the input tube 1. The first output tube 3, the second output tube 4, the third output tube 5 and the fourth output tube 6 are all located on the same side of the third bending portion 13. The first output tube 3 is bent toward one end of the fourth output tube 6, the second output tube 4 is bent toward one side of the third bending portion 13, and the first output tube 3 is located above the second output tube 4.

[0021] The input pipe 1, the first bending portion 11, the second bending portion 12, the third bending portion 13 and the inclined pipe 14 are an integrally formed structure, which is bent by a bending machine during forming to form a plurality of bending portions. By providing three bending portions, the input direction and the final output direction of the input pipe 1 can be easily adjusted, and the connection between the input pipe and the evaporator and the condenser is convenient. By providing the inclined pipe 14, the connection of each output pipe is convenient.

[0022] The third output tube 5 is arranged horizontally, and the distance between the output end of the first output tube 3 and the output end of the third output tube 5 is smaller than the distance between the output end of the second output tube 4 and the output end of the third output tube 5 .

[0023] The output ends of the first output tube 3 , the second output tube 4 , the third output tube 5 and the fourth output tube 6 are all located on the same side of the inclined tube 14 .

[0024] The first output pipe 3 includes a first straight pipe 31, a curved pipe 32, and a second straight pipe 33. The first straight pipe 31 and the second straight pipe 33 are connected through the curved pipe 32. The first straight pipe 31 is connected to the inclined pipe 14. The angle between the first straight pipe 31 and the second straight pipe 33 is 30-35°. The first output pipe 3 is an integrally formed structure. By providing the curved pipe 32, the second straight pipe 33 can be turned to the side away from the third bending portion 13, avoiding the output end of the first output pipe being too close to the outer wall of the input pipe, and facilitating the connection of the first output pipe 3 with the external structure; at the same time, it is convenient to provide sufficient space for the second output pipe 4 to bend to the side of the third bending portion, thereby facilitating the connection of multiple output pipes on the inclined pipe 14.

[0025] A constricted portion 15 is formed at one end of the input pipe 1, and the fourth output pipe 6 is matched with the constricted portion 15, and a connector 61 is provided at the matching position, and the inner diameter of the constricted portion 15 is consistent with the outer diameter of the connector 61. In actual matching, the connector 61 and the constricted portion 15 adopt an interference fit, so that the fourth output pipe 6 and the input pipe can be tightly matched and fixed. By providing the constricted portion 15, the flow rate of the refrigerant at the constricted portion 15 can be increased to a certain extent, so that the fluid can quickly enter the fourth output pipe 6 for output, avoiding the accumulation of the fluid at the connection between the input pipe 1 and the fourth output pipe 6.

[0026] The outer walls of the first output tube 3, the second output tube 4 and the third output tube 5 are all formed with limiting protrusions 7. In actual production, three bosses are formed on the side wall of the inclined tube 14, each boss is provided with a connecting hole, the connecting hole is connected to the input tube, and the first output tube 3, the second output tube 4 and the third output tube 5 are respectively matched with the connecting holes on the corresponding bosses. When one end of the first output tube 3, the second output tube 4 and the third output tube 5 is inserted into the corresponding connecting hole, the limiting protrusion 7 on the outer wall of each output tube abuts against the corresponding boss, thereby limiting the insertion depth of each output tube. In order to prevent each output tube from blocking the fluid in the output tube, the distance between the limiting protrusion 7 and the end face of the corresponding matching end of each output tube is consistent with the height of the boss, which is conducive to the fluid in the output tube being evenly distributed to each output tube.

[0027] The inner diameters of the output ends of the first output tube 3, the second output tube 4, the third output tube 5 and the fourth output tube 6 are all smaller than the inner diameters of the remaining parts of the corresponding output tubes. Thus, the fluid can maintain a relatively fast speed when flowing through the output end, avoiding the accumulation of the fluid at the outlet end and ensuring the rapid circulation of the refrigerant.

[0028] The utility model of the air conditioner evaporator copper tube assembly conveniently connected to the fins can protect the input tube 1 by providing a protective tube spring 2, reducing the deformation of each bending part. When the protective tube spring 2 is installed, one end of the protective tube spring 2 abuts against the boss 8 corresponding to the first output tube 3, and the protective tube spring 2 is limited by the boss; the other end of the protective tube spring 2 can be welded and fixed to the outer wall of the input tube 1, so as to realize the installation limit of the protective tube spring 2 on the input tube 1.

[0029] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
