In some conventional heat exchangers 1, the liquid refrigerant pipe 20 and the gaseous refrigerant pipe 30 are located on the same side of the heat exchanger 1, and therefore, the installation space of the liquid refrigerant pipe 20 is limited, and when the capillary tube 21 of the liquid refrigerant pipe 20 is installed, interference with the gas collecting branch tube 31 is likely to occur, and it is difficult to install the capillary tube 21.
In view of the above problems, the heat exchanger 1 provided in the embodiments of the present utility model can improve the convenience of installation of the liquid refrigerant pipe 20.
The specific structure of the heat exchanger 1 and the corresponding technical effects thereof according to the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
Referring to fig. 1-3, a heat exchanger 1 according to an embodiment of the present utility model includes a heat exchange body 10, a liquid refrigerant tube 20 and a gaseous refrigerant tube 30.
The liquid refrigerant pipe 20 is connected with the heat exchange body 10, the gaseous refrigerant pipe 30 comprises a plurality of gas collecting branch pipes 31 and a gas collecting center, two ends of the gas collecting branch pipes 31 are respectively connected with the heat exchange body 10 and are positioned on the same side of the heat exchange body 10 as the liquid refrigerant pipe 20, and the gas collecting branch pipes 31 are at least partially bent to avoid the liquid refrigerant pipe 20.
It is easy to understand that the liquid refrigerant tube 20 includes a plurality of capillaries 21, and the capillaries 21 are arranged at intervals along the length direction of the heat exchange body 10, and because the capillaries 21 and the gas collecting branch tube 31 are disposed on the same side of the heat exchange body 10, the installation space of the capillaries 21 is limited, and when some existing heat exchangers 1 are installed, interference occurs between the capillaries 21 and the gas collecting branch tube 31, thereby affecting the installation efficiency of the liquid refrigerant tube 20.
Referring to fig. 1, the heat exchange body 10 has a longitudinal direction a, a thickness direction b, and a width direction c. Wherein the length direction, the thickness direction and the width direction are perpendicular to each other.
In this embodiment, the gas collecting branch pipe 31 is at least partially bent to avoid the liquid refrigerant pipe 20, and in particular, in this embodiment, the gas collecting branch pipe 31 is at least partially bent to avoid the capillary tube 21 of the liquid refrigerant pipe 20, so as to avoid interference with the gas collecting branch pipe 31 when the capillary tube 21 is installed, and influence the installation efficiency of the liquid refrigerant pipe 20. Therefore, the convenience of installing the liquid refrigerant pipe 20 is improved by the arrangement that the gas collecting branch pipe 31 is at least partially bent, so that the installation efficiency of the liquid refrigerant pipe 20 is effectively improved.
Specifically, in the present embodiment, in order to further avoid interference between the gas collecting branch pipe 31 and the capillary tube 21 of the liquid refrigerant pipe 20 during installation, one end of the gas collecting branch pipe 31 away from the gas collecting main pipe 32 and the liquid refrigerant pipe 20 are respectively disposed at two ends of the same side of the heat exchange body 10.
Specifically, in the thickness direction, one end of the gas collecting branch pipe 31, which is far from the gas collecting main pipe 32, is provided at both ends on the same side of the heat exchange body 10 as the capillary tube 21 of the liquid refrigerant pipe 20. So as to ensure that the gas collecting branch pipe 31 and the capillary tube 21 have enough distance in the thickness direction, and avoid the interference of the gas collecting branch pipe 31 and the capillary tube 21 during installation as much as possible.
The ends of the manifold 31 on the same side as the capillary tube 21 in the thickness direction should not be construed as being exactly opposite ends, but may be substantially opposite ends.
Of course, in some alternative embodiments, the gas collecting branch pipe 31 and the capillary tube 21 are not provided at both ends of the heat exchange body 10 in the thickness direction, respectively.
Specifically, in this embodiment, the gas collecting branch pipe 31 includes a first branch section 311, a second branch section 312 and a third branch section 313 that are connected in order by an included angle, one end of the first branch section 311 away from the second branch section 312 is connected with the heat exchange body 10, in the thickness direction of the heat exchange body 10, the second branch section 312 extends from the first branch section 311 along the direction away from the liquid refrigerant pipe 20, and one end of the third branch section 313 away from the second branch section 312 is connected with the gas collecting main 32.
The second branch section 312 extends from the first branch section 311 in a direction away from the liquid refrigerant pipe 20 in the thickness direction of the heat exchange body 10, in other words, gradually away from the liquid refrigerant pipe 20 in a direction in which the second branch section 312 is away from the first branch section 311. By providing the second branch section 312, the interference between the manifold 31 and the capillary 21 can be effectively avoided. And further, the convenience of the installation of the capillary tube 21, that is, the convenience of the installation of the liquid refrigerant tube 20 is improved, thereby improving the installation efficiency of the liquid refrigerant tube 20.
It should be noted that, in some alternative real-time modes, the gas collecting branch pipe 31 may include only the first branch section 311 and the second branch section 312 connected at an included angle.
Further, in the present embodiment, the first branch section 311 is connected to the second branch section 312 in a circular arc transition manner. It can be understood that the arc transition connection between the first branch section 311 and the second branch section 312 can ensure that the bending section of the first branch section 311 and the second branch section 312 is not suddenly changed, so as to avoid abrupt change of the pressure of the gaseous refrigerant at the connection section of the first branch section 311 and the second branch section 312, and ensure relatively stable speed flow of the gaseous refrigerant at the connection section of the first branch section 311 and the second branch section 312.
In addition, because the first branch section 311 is in arc transition connection with the second branch section 312, the phenomenon of stress concentration at the connection position of the first branch section 311 and the second branch section 312 can be avoided, and the service life of the gas collecting branch pipe 31 is further ensured.
Also, in this embodiment, the second leg 312 is connected to the third leg 313 in a circular arc transition. The arc transition connection between the second branch section 312 and the third branch section 313 can avoid the phenomenon of stress concentration at the connection part of the second branch section 312 and the third branch section 313, ensure the service life of the gas collecting branch pipe 31, avoid abrupt change of the bending sections of the second branch section 312 and the third branch section 313, avoid abrupt change of the pressure of the gaseous refrigerant at the connection part of the second branch section 312 and the third branch section 313, and ensure the relatively stable speed flow of the gaseous refrigerant at the connection part of the second branch section 312 and the third branch section 313.
Of course, in other embodiments, in the manifold 31, the first branch section 311 may be connected with the second branch section 312 in a circular arc transition, or the second branch section 312 may be connected with the third branch section 313 in a circular arc transition.
Further, the third branch section 313 is parallel to the first branch section 311, and it can be understood that, since the second branch section 312 is gradually far from the liquid refrigerant tube 20 in the thickness direction, the third branch section 313 is parallel to the first branch section 311, so that the dimension in the thickness direction can be ensured. The size of the heat exchanger 1 in the thickness direction is reduced.
Further, the second branch section 312 gradually gets away from the heat exchange body 10 in a direction away from the first branch section 311. In other words, the second branch section 312 has no trend of approaching the heat exchange body 10 in the direction away from the first branch section 311, so that the second branch section 312 has a smaller bending width, and the gaseous refrigerant flows in the second branch section 312 more stably.
Further, the plurality of gas collecting branch pipes 31 are arranged at intervals along the extending direction of the gas collecting main pipe 32, and the extending direction of the gas collecting main pipe 32 is consistent with the length direction of the heat exchange body 10, and it can be understood that through the arrangement, the gas collecting main pipe 32 and the heat exchange body 10 are arranged in parallel, so that the space occupied by the heat exchange body 10 and the gas collecting main pipe 32 is reduced.
Further, in order to ensure the tightness of the connection between the gas collecting branch pipe 31 and the gas collecting main pipe 32 and the heat exchange body 10, a sealing member (not shown) is provided on the side of the gas collecting branch pipe 31 connected to the gas collecting main pipe 32, and a sealing member is provided on the side of the gas collecting branch pipe 31 connected to the heat exchange body 10.
The embodiment of the utility model also provides an air conditioner which comprises a heat exchange device, a pipeline and the heat exchanger 1. The heat exchange device is connected with a gaseous refrigerant pipe 30 or a liquid refrigerant pipe 20 of the heat exchanger 1 through a pipeline.
In the present embodiment, the air conditioner refers to a refrigerator.
In summary, the embodiment of the utility model provides a heat exchanger 1 including a heat exchange body 10, a liquid refrigerant tube 20 and a gaseous refrigerant tube 30. The liquid refrigerant pipe 20 is connected with the heat exchange body 10, the gaseous refrigerant pipe 30 comprises a plurality of gas collecting branch pipes 31 and a gas collecting mesoscopic view, two ends of the gas collecting branch pipes 31 are respectively connected with the heat exchange body 10 and are positioned on the same side of the heat exchange body 10 with the liquid refrigerant pipe 20, and the gas collecting branch pipes 31 are at least partially bent to avoid the liquid refrigerant pipe 20, so that interference with the gas collecting branch pipes 31 during installation of the capillary tube 21 can be avoided, and the installation efficiency of the liquid refrigerant pipe 20 is affected. Therefore, the convenience of installing the liquid refrigerant pipe 20 is improved by the arrangement that the gas collecting branch pipe 31 is at least partially bent, so that the installation efficiency of the liquid refrigerant pipe 20 is effectively improved.
