With the advent of the internet+ age, new application demands are constantly affecting. The popularization of high-definition videos such as 4K, 8K and the like has the problem that the requirements of consumers on transmission bandwidths are continuously improved, and communication equipment is continuously updated. In order to meet the support requirements of operators on services such as high transmission speed, large capacity, high integration and the like, the existing communication equipment continuously upgrades the functions of the communication equipment, the integration of the communication equipment is continuously improved, and the power is rapidly increased.

Currently, communication devices are typically disposed within a cabinet to form a cabinet. As the power of communication equipment continues to increase, the overall power density of the cabinets has approached 20kW and there is still a continuing trend. The heat dissipation mode of current rack can't satisfy the heat dissipation demand, and in the heat dissipation in-process, the heat dissipation between the communication equipment can influence each other, leads to the radiating effect of rack relatively poor, influences communication equipment's normal work.

Based on this, an embodiment of the present utility model provides a cabinet, as shown in fig. 1, and fig. 1 is a schematic overall structure of a cabinet 100 according to an embodiment of the present utility model. The cabinet 100 may include a housing 10, a plurality of sets of communication devices 20, and at least one first heat exchanger 30.

As shown in fig. 2, fig. 2 is a schematic diagram of the overall structure of a housing 10 according to an embodiment of the present utility model, wherein a mounting cavity 101 is formed in the housing 10, and a first air inlet 102 and a first air outlet 103 are provided and are communicated with the mounting cavity 101. As shown in fig. 1, the plurality of sets of communication devices 20 are disposed in a mounting chamber 101 (fig. 2) formed inside the housing 10, and arranged in the flow direction of the air flow in the mounting chamber 101 (fig. 2).

Illustratively, as shown in fig. 2, the air flow in the installation chamber 101 generally flows in the up-down direction, and correspondingly, as shown in fig. 1, the plurality of sets of communication devices 20 are arranged inside the housing 10 in the up-down direction.

Because the shell 10 is provided with the first air inlet 102 and the first air outlet 103 which are communicated with the installation cavity 101, external air can enter through the first air inlet 102, and flows out from the first air outlet 103 after exchanging heat with the plurality of groups of communication equipment 20 in the installation cavity 101, so that airflow circulation between the shell 10 and the outside is realized.

As shown in fig. 1, each group of communication devices 20 may include a plurality of communication device assemblies 21, and the communication device assemblies 21 may have a plate shape. Each communication device assembly 21 may include a circuit board (not shown) and a functional module (not shown). The circuit board and the functional module generate a certain amount of heat during operation.

In order to secure the heat radiation effect of the cabinet 100, as shown in fig. 1, at least one first heat exchanger 30 is provided between two adjacent sets of communication devices 20 along the flow direction of the air flow in the installation cavity 101 (fig. 2) formed inside the housing 10. Thus, after the air exchanges heat with one of the two adjacent sets of communication devices 20, it passes through the at least one first heat exchanger 30 to exchange heat with the first heat exchanger 30. Then, when the air with lower temperature after heat exchange with the first heat exchanger 30 and heat exchange with another group of communication equipment 20, the heat exchange efficiency is higher, and the heat exchange effect is better.

Therefore, in the cabinet 100 provided by the embodiment of the utility model, by arranging the first heat exchanger 30 between two adjacent groups of communication devices 20, each group of communication devices 20 can exchange heat with air with lower temperature, so that the heat exchange efficiency of the communication devices 20 is ensured, and the overall heat dissipation effect of the cabinet 100 is improved. Meanwhile, since the first heat exchanger 30 is disposed inside the case 10 at a relatively close distance from the communication device 20, heat dissipation efficiency can be improved.

It will be appreciated that one first heat exchanger 30 may be disposed between two adjacent sets of communication devices 20, or a plurality of first heat exchangers 30 may be disposed, and in this embodiment of the present utility model, in order to reduce the number of first heat exchangers 30 and reduce the cost of the cabinet 100, as shown in fig. 1, one first heat exchanger 30 is disposed between two adjacent sets of communication devices 20. Of course, a plurality of first heat exchangers 30 may be disposed between two adjacent sets of communication devices 20, so as to improve heat exchange efficiency and ensure heat exchange effect.

Further, it is understood that the number of first heat exchangers 30 may be set according to the number of communication devices 20 within the housing 10. Illustratively, as shown in FIG. 1, three sets of communication devices 20 are disposed within the housing 10. Correspondingly, the number of the first heat exchangers 30 may be two, and are respectively disposed between two adjacent sets of communication devices 20.

In some embodiments, as shown in fig. 1, cabinet 100 may also include a second heat exchanger 40. The second heat exchanger 40 is disposed in a mounting cavity 101 (fig. 2) formed in the housing 10, and is disposed on a side of the plurality of groups of communication devices 20 near the first air inlet 102 (fig. 2) and opposite to the first air inlet 102 (fig. 2).

In this way, when the outside air enters the installation cavity 101 of the housing 10 through the first air inlet 102, the outside air exchanges heat with the second heat exchanger 40 and becomes cold air with a lower temperature. The cool air with a lower temperature can then exchange heat with a group of communication devices 20 near the first air inlet 102, so as to ensure the heat exchange effect of the group of communication devices 20.

Therefore, as shown in fig. 1, by setting the first heat exchanger 30 and the second heat exchanger 40, the multiple groups of communication devices 20 in the shell 10 have better heat exchange effect, so that heat generated by the communication devices 20 in the working process can be timely dissipated, and the communication devices 20 can be ensured to maintain a normal running state.

In some embodiments, the first heat exchanger 30 may be a sensible heat exchanger. In this way, since the first heat exchanger 30 is a sensible heat exchanger, condensed water is not generated in the heat exchange process of the first heat exchanger 30, so that the problem that the condensed water falls onto the communication equipment 20 to cause damage to the communication equipment 20 is avoided.

Similarly, the second heat exchanger 40 may also be a sensible heat exchanger. Thus, the second heat exchanger 40 also does not generate condensed water during the heat exchange.

In some embodiments, as shown in fig. 1, cabinet 100 may also include an outer housing 50. The inside of the outer case 50 forms a receiving chamber 501, and the case 10 is disposed in the receiving chamber 501. As shown in fig. 3, fig. 3 is a schematic diagram of the overall structure of the outer casing 50 according to the embodiment of the present utility model, where the outer casing 50 is provided with a second air inlet 502 and a second air outlet 503.

Since the housing 10 is disposed in the outer housing 50, the outer housing 50 can protect the housing 10. Meanwhile, since the casing 10 is disposed inside the outer casing 50, the air with a high temperature outside does not directly contact the casing 10, and the outer casing 50 can have a certain effect of heat insulation.

Since the outer housing 50 is provided with the second air inlet 502 and the second air outlet 503, the external air can enter the outer housing 50 through the second air inlet 502 and enter the installation cavity 101 of the housing 10 through the first air inlet 102 for heat exchange. The heat-exchanged hot air may sequentially pass through the first air outlet 103 and the second air outlet 503 to be discharged outside the outer case 50.

In some embodiments, as shown in fig. 4, fig. 4 is a schematic diagram illustrating connection between the first heat exchanger 30 and the second heat exchanger 40 according to an embodiment of the present utility model, the cabinet 100 may further include a refrigerant conveying pipe 61, a refrigerant return pipe 62, a plurality of refrigerant conveying branch pipes 63, and a plurality of refrigerant return branch pipes 64.

The refrigerant delivery pipe 61 may be provided in the outer case 50 at one side of the case 10. The refrigerant pipe 61 is connected to a refrigeration system. In this way, the refrigerant of the refrigeration system can flow through the refrigerant pipe 61. The refrigerant return pipe 62 is provided in the outer case 50, and is connected to the refrigeration system at a side of the case 10 close to the refrigerant feed pipe 61. The refrigerant may flow back into the refrigeration system through the refrigerant return line 62.

Because the refrigerant conveying pipe 61 and the refrigerant return pipe 62 are arranged in the outer shell 50, the accommodating cavity 501 can provide installation space for the refrigerant conveying pipe 61 and the refrigerant return pipe 62, and the refrigerant conveying pipe 61 and the refrigerant return pipe 62 can be fixed in the outer shell 50, so that the arrangement is more convenient.

The refrigeration system may be disposed inside the outer casing 50 or may be disposed outside the outer casing 50, specifically, may be disposed according to the size of the outer casing 50. The refrigeration system may include a compressor, an evaporator, etc. to absorb and release heat from the refrigerant.

The housing 10 may be provided with a plurality of relief ports (not shown). One end of the refrigerant conveying branch pipe 63 is communicated with the refrigerant conveying pipe 61, and the other end is arranged in the avoiding port in a penetrating way and is connected with the first heat exchanger 30. One end of the refrigerant return branch pipe 64 is communicated with the refrigerant return pipe 62, and the other end is arranged in the avoiding port in a penetrating way and is connected with the first heat exchanger 30. Wherein a first heat exchanger 30 communicates with a refrigerant delivery manifold 63 and a refrigerant return manifold 64.

Thus, the refrigerant can flow from the refrigeration system into the first heat exchanger 30 for heat exchange and flow back from the first heat exchanger 30 into the refrigeration system through the refrigerant delivery branch pipe 63 and the refrigerant return branch pipe 64. Because the shell 10 is provided with the avoiding opening, the refrigerant conveying branch pipe 63 and the refrigerant return branch pipe 64 can conveniently extend into the shell 10 to be communicated with the first heat exchanger 30.

Similarly, the second heat exchanger 40 may also be connected to a refrigerant delivery manifold 63 and a refrigerant return manifold 64 to effect the circulating flow of refrigerant from the refrigeration system to the second heat exchanger 40 and back to the refrigeration system by the second heat exchanger 40.

In some embodiments, the first air inlet 102 may be disposed on a side of the housing 10 adjacent to the second air inlet 502, opposite to the second air inlet 502. The first air outlet 103 may be disposed on a side of the housing 10 near the second air outlet 503, opposite to the second air outlet 503.

In this way, air entering the interior of the outer housing 50 from the second air inlet 502 may more easily enter the housing 10 through the first air inlet 102 for heat exchange. Meanwhile, the air flowing out of the housing 10 from the first air outlet 103 can be directly discharged from the second air outlet 503, so that a large amount of hot air is prevented from being left in the outer housing 50 and cannot be discharged.

As shown in fig. 3, the outer case 50 may include an outer top plate 51, an outer side plate 52, and an outer bottom plate 53.
