Description

Technical Field

[0001] The utility model relates to the technical field of communication base station radiators, in particular to a heat exchanger for a communication base station. Background Art

[0002] A communication base station is a form of radio station, which refers to a radio transceiver station that transmits information to mobile phone terminals through a mobile communication exchange center within a certain radio coverage area. With the advent of the 5G era, communication base stations equipped with 5G signals are also updated. The power consumption of a 5G base station is about 2.5 to 4 times that of a 4G base station. In order to maintain the stability of the 5G signal within the same radio coverage area, the increase in the power consumption of the communication base station also means an increase in its heat generation. If the existing heat exchanger equipped for the 4G base station is used, insufficient heat dissipation will occur. If the operating temperature inside the communication base station exceeds the rated operating temperature and continues to work for a long time, it will cause the signal in the area to fluctuate, affecting the network stability. It will also affect the service life of the communication base station, so improvements are needed. Utility Model Content

[0003] The main purpose of the utility model is to provide a heat exchanger for a communication base station, aiming to provide a heat exchanger for a communication base station with high heat dissipation efficiency.

[0004] To achieve the above-mentioned purpose, the present invention proposes a heat exchanger for a communication base station, comprising a plurality of heat dissipation fin groups, each heat dissipation fin group being stacked in a vertical direction to form a heat exchanger main body, an external circulation air duct being formed between two adjacent heat dissipation fin groups, and an internal circulation air duct being formed inside each heat dissipation fin group, so as to realize the mutually spaced stacking arrangement of the external circulation air duct and the internal circulation air duct on the heat exchanger main body.

[0005] Specifically, any of the heat dissipating fin groups includes two heat dissipating fin bodies, and the heat dissipating fin body includes a fin body and connecting parts respectively provided at both ends of the fin body, and the connecting parts located at different ends of the fin body are mirror-imaged.

[0006] Specifically, the two heat dissipation fin bodies of any heat dissipation fin group are arranged in a mirror image.

[0007] Specifically, a connection angle is formed between the connection portion and the fin body.

[0008] Specifically, air guide blades are respectively provided on both sides of the fin body adjacent to the connecting portion, and the air guide blades located on different sides of the fin body are arranged in a mirror image.

[0009] Specifically, the air guide plates and the fin bodies are staggered to form air guide grooves, and the notches of the air guide grooves on both sides of the fin bodies are set in opposite directions. When the two fin bodies are combined to form a heat dissipation fin group, the air guide plates on the same side form the inner circulation air duct through the air guide grooves. When at least two heat dissipation fin groups are stacked, the outer circulation air duct is formed on the side opposite to the inner circulation air duct between adjacent heat dissipation fin groups through the air guide plates.

[0010] Specifically, a plurality of heat dissipation holes are evenly distributed on the fin body, and the heat dissipation holes on each heat dissipation fin group are connected in the vertical direction.

[0011] Specifically, the heat dissipation holes are arranged on both sides of the heat dissipation fin body close to the air guide plate. The center points of the heat dissipation holes on different sides correspond one to one and are located on the same vertical axis, and the center points of the heat dissipation holes on the same side correspond one to one and are located on the same horizontal axis.

[0012] Specifically, a plurality of inner grooves are provided on the fin body, the heat dissipation holes are provided in the inner grooves, and the inner grooves provided on different sides have opposite concave and convex directions.

[0013] Specifically, the heat dissipation fin body is coated with a graphene coating.

[0014] The technical solution of the present invention forms an internal circulation air duct inside the heat dissipation fin group and then forms an external circulation air duct between two adjacent heat dissipation fin groups. The internal circulation air duct and the external circulation air duct cooperate with each other to improve the heat dissipation capacity of the heat exchanger, thereby facilitating the normal use of the communication base station.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them.

[0022] like Figures 1 to 3 As shown, a heat exchanger for a communication base station includes multiple groups of heat dissipation fins 10, each of which is stacked vertically to form the heat exchanger body. An outer circulation air duct 12 is formed between two adjacent heat dissipation fin groups 10, and an inner circulation air duct 11 is formed within each heat dissipation fin group 10, so that the outer circulation air ducts 12 and the inner circulation air ducts 11 are stacked and spaced apart on the heat exchanger body. When the communication base station is in use, the inner circulation air duct 11 is formed within the heat dissipation fin group 10, and the outer circulation air duct 12 is formed between two adjacent heat dissipation fin groups 10. The inner circulation air duct 11 and the outer circulation air duct 12 cooperate to improve the heat dissipation capacity of the heat exchanger, thereby facilitating the normal operation of the communication base station.

[0023] Each heat sink assembly 10 includes two heat sink bodies 20. Each heat sink body 20 includes a fin body 30 and connecting portions 31 located at each end of the fin body 30. The connecting portions 31 located at different ends of the fin body 30 are arranged in a mirror image. In this embodiment, the heat sink assembly 10 is formed by connecting the two heat sink bodies 20 in a mirror image relationship, thereby achieving rapid assembly of the heat sink assembly 10.

[0024] The two fin bodies 20 of any fin assembly 10 are arranged in mirror-image configuration; a connection angle is formed between the connecting portion 31 and the fin body 30. In this embodiment, the fin assembly 10 is formed by adhesively connecting the two fin bodies 20 through the connecting portions 31. This ensures the stability of the fin assembly 10 while facilitating quick connection of the fin bodies 20 through the connecting portions 31. Alternatively, the two fin bodies 20 can be fixedly connected by screws.

[0025] Air guides 32 are provided on both sides of the fin body 30 adjacent to the connecting portion 31. The air guides 32 on different sides of the fin body 30 are mirror images. In this embodiment, the air guides 32 are provided on both sides of the fin body 30 to enhance the air conduction rate of the heat dissipating fin body 20, thereby improving the heat dissipation effect.

[0026] The air guides 32 and the fin bodies 30 are staggered to form air guide grooves 33. The notches of the air guide grooves 33 on both sides of the fin bodies 30 are arranged in opposite directions. When the two fin bodies 30 are combined to form the heat dissipation fin group 10, the air guides 32 on the same side form the inner circulation air duct 11 through the air guide grooves 33. When at least two heat dissipation fin groups 10 are stacked, the outer circulation air duct 12 is formed on the side opposite to the inner circulation air duct 11 between the adjacent heat dissipation fin groups 10 through the air guides 32. In this embodiment, by forming air guide grooves 33 with different directions on both sides of the fin body 30, it is convenient to form the inner circulation air duct 11 and the outer circulation air duct 12, thereby facilitating the improvement of the heat dissipation effect of the heat exchanger, so that the heat exchanger can better cope with the power consumption of the 5G base station.

[0027] The fin body 30 is evenly distributed with a plurality of heat dissipation holes 34. The heat dissipation holes 34 on each heat dissipation fin group 10 are vertically interconnected. The heat dissipation holes 34 are located on both sides of the heat dissipation fin body 30 near the air guide fin 32. The center points of the heat dissipation holes 34 on different sides correspond one-to-one and lie on the same vertical axis, while the center points of the heat dissipation holes 34 on the same side correspond one-to-one and lie on the same transverse axis. The fin body 30 is provided with a plurality of inner grooves 35. The heat dissipation holes 34 are located within the inner grooves 35. The inner grooves 35 on different sides have opposite concave and convex directions. In this embodiment, the multiple heat dissipation holes 34 are provided on the fin body 30 to enhance the heat dissipation effect of the fin body 30 through the heat dissipation holes 34. The inner grooves 35 also facilitate guiding the signal transmitter, thereby improving assembly efficiency.

[0028] The heat dissipation fin body 20 is coated with a graphene coating. In this embodiment, the heat dissipation fin body 20 is coated with a graphene coating, thereby further improving the heat dissipation efficiency of the heat dissipation fin body 20.
