[0027] like Figures 1 to 4 As shown, in an illustrative embodiment of the heat dissipation mechanism of the utility model applied to a cable channel, the heat dissipation mechanism applied to the cable channel includes a channel body 1, and the channel body 1 is divided into a cable bin 11 and a heat dissipation bin 12 located outside the cable bin 11 by a partition.
[0028] The cable compartment 11 is further divided into a first cable compartment 11A and a second cable compartment 11B located below the first cable compartment 11A by a partition. Both the first cable compartment 11A and the second cable compartment 11B contain cables 2 .
[0029] The heat dissipation chamber 12 is provided with a first heat exchanger 31 and a second heat exchanger 32, and the first heat exchanger 31 is located above the second heat exchanger 32. An air inlet 41 and an air outlet 42 are provided on the side plate outside the heat dissipation chamber 12, the air outlet 42 is located at the top and is provided with a fan 5, and the air inlet 41 is located at the bottom.
[0030] The first heat exchanger 31 is connected to the first heat dissipation pipeline 61 through a water pump, and the second heat exchanger 32 is connected to the second heat dissipation pipeline 62 through a water pump. The first heat dissipation pipeline 61 extends to the bottom of the first cable compartment 11A, and the second heat dissipation pipeline 62 extends to the bottom of the second cable compartment 11B.
[0031] Driven by the water pump, the first coolant flows between the first heat dissipation pipeline 61 and the first heat exchanger 31, and the second coolant flows between the second heat dissipation pipeline 62 and the second heat exchanger 32. Under the action of the fan 5, the airflow enters the heat dissipation chamber 12 through the air inlet 41, flows through the second heat exchanger 32 and the first heat exchanger 31, and is discharged through the air outlet 42.
[0032] The heat generated by the cable 2 during operation is transferred to the first coolant in the first heat dissipation pipeline 61 and the second coolant in the second heat dissipation pipeline 62. The first coolant and the second coolant that absorb the heat flow to the first heat exchanger 31 and the second heat exchanger 32 respectively. The airflow that flows through the second heat exchanger 32 and the first heat exchanger 31 in turn takes away the heat and is discharged to the outside of the channel body 1 through the air outlet 42, thereby efficiently realizing the heat dissipation of the cable 2.
[0033] The airflow only flows in the heat dissipation compartment 12, and the cable 2 is enclosed in the cable compartment 11, avoiding direct contact between the airflow and the cable 2, thereby preventing dust from contacting the cable 2, so that the cable 2 is always in a closed and clean space, thereby increasing the life of the cable 2.
[0034] The cable bin 11 is divided into two parts, the upper and lower parts, and the cables 2 are divided into two parts and respectively placed in the corresponding cable bins 11, so as to avoid the heat concentration caused by the concentrated arrangement of the cables 2, and make the heat generated by the cables 2 more dispersed, thereby making it easier to dissipate heat.
[0035] The heat emitted by the cable 2 in the lower second cable compartment 11B will rise and exchange heat with the first coolant in the first heat dissipation pipeline 61. At the same time, the heat emitted by the cable 2 in the upper first cable compartment 11A will also exchange heat with the first coolant in the first heat dissipation pipeline 61 nearby. The second coolant in the second heat dissipation pipeline 62 only exchanges heat with the heat emitted by the cable 2 in the second cable compartment 11B, so that the temperature of the first coolant in the cable compartment 11 is higher than that of the second coolant. After the airflow enters the heat dissipation compartment 12, it first exchanges heat with the low-temperature second coolant, and then exchanges heat with the high-temperature first coolant. Since the temperature of the second coolant is relatively low, the temperature of the airflow increases less after heat exchange with it, and still has a high temperature difference with the high-temperature first coolant, so that the heat in the first coolant can be efficiently taken away by the airflow, so that the heat in the first coolant and the second coolant can be efficiently taken away by the airflow, further improving the heat dissipation efficiency.
[0036] In the above-mentioned schematic embodiment, the heat dissipation mechanism applied to the cable channel transfers the heat dissipated by the cable to the heat exchanger in the outer heat dissipation bin through the heat dissipation pipeline, so that the airflow introduced into the heat dissipation bin by the fan takes away the heat from the heat exchanger, and the heat dissipated by the cable at the center position is efficiently dissipated. Not only is the heat dissipation effect good, but the cables located in the cable bin will not come into contact with the airflow, thereby ensuring the cleanliness of the environment in which the cables are located, allowing the cables to work stably for a long time, and solving the problems of poor heat dissipation effect and reduced performance of power distribution equipment in prefabricated cable channel modules.
[0037] In some embodiments, the first heat dissipation pipeline 61 extends outward from the bottom plate of the first cable compartment 11A to the side plate of the first cable compartment 11A, and then connects to the first heat exchanger 31. The second heat dissipation pipeline 62 extends outward from the bottom plate of the second cable compartment 11B to the side plate of the second cable compartment 11B, and then connects to the second heat exchanger 32.
[0038] The heat dissipation pipelines all extend from the bottom of the corresponding cable compartment 11 to the side panel on one side, so that they can surround the cables 2 in the cable compartment 11 to a certain extent, and then fully take away the heat generated by the cables 2 at work, thereby improving the heat dissipation efficiency. In addition, when the low-temperature second coolant flows upward along the side panel to the second heat exchanger 32, it can exchange heat with the airflow flowing into the air inlet 41 to a certain extent, increasing the heat exchange time between the second coolant and the airflow, allowing the airflow to more fully take away the heat in the second coolant, further improving the heat dissipation efficiency.
[0039] In some embodiments, the first heat exchanger 31 and the second heat exchanger 32 are both located at the top of the heat dissipation bin 12, so that the second heat dissipation pipe 62 extends to the side panel of the first cable bin 11A, and a section of the top of the second heat dissipation pipe 62 is adjacent to the first heat dissipation pipe 61. The low-temperature second coolant can exchange heat with the first coolant to a certain extent, thereby transferring part of the heat in the first cable bin 11A to the airflow through the second coolant, thereby improving the heat dissipation efficiency.
[0040] In some embodiments, both ends of the first heat exchanger 31 and both ends of the second heat exchanger 32 extend to the inner side plate and the outer side plate of the heat dissipation bin 12 respectively, and the first heat exchanger 31 and the second heat exchanger 32 are both inclined relative to the horizontal plane.
[0041] The heat exchanger is tilted and completely distributed over the width of the heat dissipation bin 12, so that the heat exchanger has a longer length in the heat dissipation bin 12 with limited width, thereby increasing the heat dissipation area of the heat exchanger and improving the heat dissipation efficiency.
[0042] In some embodiments, the first heat exchanger 31 and the second heat exchanger 32 are stacked so that the first heat exchanger 31 and the second heat exchanger 32 overlap to the maximum extent in the airflow direction. The airflow can more efficiently pass through the first heat exchanger 31 and the second heat exchanger 32 in sequence, thereby improving the efficiency of the airflow step heat exchange.
[0043] In some embodiments, Figure 3 As shown, the first heat dissipation pipeline 61 and the second heat dissipation pipeline 62 are arranged in a serpentine shape, which increases the distribution area and total length of the heat dissipation pipeline, enables the heat dissipation pipeline to have a more sufficient heat exchange with the cable compartment 11, and improves the heat dissipation efficiency.
[0044] In some embodiments, there are two heat dissipation chambers 12, which are respectively located on both sides of the cable chamber 11. The two heat dissipation chambers 12 are both equipped with a first heat exchanger 31 and a second heat exchanger 32. There are two first heat dissipation pipes 61 and two second heat dissipation pipes 62. The two first heat dissipation pipes 61 are respectively connected to the corresponding first heat exchangers 31, and the two second heat dissipation pipes 62 are respectively connected to the corresponding second heat exchangers 32. The heat in the same cable chamber 11 can be transferred to the heat exchangers in the heat dissipation chambers 12 on both sides through the heat dissipation pipes, and then the heat is taken away by the airflow in the two heat dissipation chambers 12, further improving the heat dissipation efficiency.
[0045] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0046] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
