Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, and in particular to a surface cooler and mounting sleeve. Background Technology

[0002] The refrigerant is an important component in a refrigeration and air conditioning system. It is mainly used to cool and dehumidify the air. Its working principle is that the refrigerant flows inside the pipe and exchanges heat with the air outside the pipe to achieve the cooling process.

[0003] Conventional-shaped surface coolers are relatively large in size. For example, CN105588452A discloses a multi-loop finned surface cooler. This type of surface cooler requires a large installation space during installation and use. When the installation space is limited, the airflow is affected, reducing the heat exchange efficiency of the surface cooler.

[0004] Therefore, a surface cooler is proposed to address the aforementioned problems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a surface cooler and its mounting sleeve, which can improve the airflow effect of the surface cooler.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a heat exchanger includes a sleeve, the sleeve is circular, a through groove is provided on the upper part of the sleeve, a surface cooler is provided inside the sleeve, the cross-section of the surface cooler is fan-shaped, and the protruding part of the surface cooler is close to the through groove of the sleeve.

[0007] By setting up a sleeve, the airflow enters through the channel and exits from both ends of the sleeve, making the airflow more concentrated. The cross-section of the surface cooler is fan-shaped, and there is a cavity between the surface cooler and the circular sleeve to facilitate airflow.

[0008] A surface cooler for a heat exchanger includes heat exchange fins and water pipes. The heat exchange fins are fan-shaped, and multiple heat exchange fins are evenly arranged to form a fin group. Multiple water pipes pass through the fin group and are connected by elbows to form a coil.

[0009] The fan-shaped heat exchange fins reduce the volume of the heat exchange fins, making it easier to install inside the circular sleeve, while also creating an airflow channel between the surface cooler and the sleeve.

[0010] Preferably, the coil includes a first channel and a second channel, which are separated at the fin assembly. The first channel is provided with a first inlet and a first outlet, and the second channel is provided with a second inlet and a second outlet.

[0011] The coil is divided into a first channel and a second channel. By setting up the first channel and the second channel, the water flow rate can be increased.

[0012] Preferably, the first inlet, the first outlet, the second inlet, and the second outlet are all located at one end of the fin assembly, the first inlet and the second inlet are adjacent to each other, the first inlet is located below the second inlet, the first outlet and the second outlet are adjacent to each other, and the first outlet is located below the second outlet.

[0013] Preferably, the first inlet and the second inlet are connected to the main inlet, and the first outlet and the second outlet are connected to the main outlet.

[0014] The first and second water inlets are adjacent to each other, and the first and second water outlets are adjacent to each other, which facilitates the installation of the main water inlet and the main water outlet.

[0015] Preferably, a first baffle and a second baffle are provided at both ends of the fin assembly, and multiple water pipes pass through the first baffle and the second baffle. A mounting platform is provided on both the first baffle and the second baffle, and the mounting platform is perpendicular to the first baffle and the second baffle. A mounting hole is provided on the mounting platform.

[0016] The water pipe is positioned by setting a first baffle and a second baffle, and the surface cooler is conveniently installed through the mounting holes.

[0017] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0018] By setting up a sleeve, the airflow enters from the through groove and exits from both ends of the sleeve, making the airflow more concentrated.

[0019] The coil is divided into a first channel and a second channel. By setting up the first channel and the second channel, the water flow rate can be increased. Attached Figure Description

[0028] like Figures 1 to 5 As shown, a heat exchanger includes a circular sleeve 16. A through groove 17 is provided on the top of the sleeve 16, and a surface cooler is disposed inside the sleeve 16. The surface cooler has a fan-shaped cross-section, and its protruding part is close to the through groove 17 of the sleeve 16. By setting the sleeve 16, airflow enters through the through groove 17 and exits from both ends of the sleeve 16, making the airflow more concentrated. The fan-shaped cross-section of the surface cooler and the cavity between the surface cooler and the circular sleeve 16 facilitate airflow.

[0029] A surface cooler for a heat exchanger includes heat exchange fins 1 and water pipes 2. The heat exchange fins 1 are fan-shaped, and multiple heat exchange fins 1 are evenly arranged to form a fin group 3. Multiple water pipes 2 pass through the fin group 3 and are connected by elbows 4 to form a coil 5. The fan-shaped heat exchange fins 1 reduce the volume of the heat exchange fins 1, making it easier to install inside a circular sleeve 16, while also creating an airflow channel between the surface cooler and the sleeve.

[0030] The coil 5 includes a first channel and a second channel, which are separated at the fin assembly 3. The first channel has a first inlet 6 and a first outlet 8, and the second channel has a second inlet 7 and a second outlet 9. The coil 5 is divided into a first channel and a second channel to increase the water flow rate.

[0031] The first inlet 6, the first outlet 8, the second inlet 7, and the second outlet 9 are all located at one end of the fin assembly 3. The first inlet 6 and the second inlet 7 are adjacent to each other, and the first inlet 6 is located below the second inlet 7. The first outlet 8 and the second outlet 9 are adjacent to each other, and the first outlet 8 is located below the second outlet 9.

[0032] The first inlet 6 and the second inlet 7 are connected to the main inlet 10, and the first outlet 8 and the second outlet 9 are connected to the main outlet 11. The first inlet 6 and the second inlet 7 are adjacent to each other, and the first outlet 8 and the second outlet 9 are adjacent to each other, which facilitates the installation of the main inlet 10 and the main outlet 11.

[0033] A first baffle 12 and a second baffle 13 are provided at both ends of the fin assembly 3. Multiple water pipes 2 pass through the first baffle 12 and the second baffle 13. A mounting platform 14 is provided on both the first baffle 12 and the second baffle 13. The mounting platform 14 is perpendicular to the first baffle 12 and the second baffle 13. A mounting hole 15 is provided on the mounting platform 14. The first baffle 12 and the second baffle 13 are used to position the water pipes 2, and the mounting hole 15 facilitates the installation of the surface cooler.

[0034] Working principle: By setting up the sleeve 16, the airflow enters from the through groove 17 and exits from both ends of the sleeve 16, making the airflow more concentrated. The cross-section of the surface cooler is fan-shaped, and there is a cavity between the surface cooler and the circular sleeve 16 to facilitate airflow. Multiple fan-shaped heat exchange fins 1 form a fin group 3. The first channel and the second channel are installed on the fin group 3 for heat exchange. The total water inlet 10 and the total water outlet 11 connect the first channel and the second channel to realize the dual-channel heat exchange cycle.
