[0002] With increasing global focus on energy conservation, emission reduction, and sustainable development, low-temperature waste cooling resources generated in industrial production, refrigeration systems, and data centers are gradually becoming an important research direction for achieving energy-efficient utilization. Low-temperature waste cooling typically refers to cold energy with a temperature between 0℃ and 20℃, such as low-temperature cooling water discharged from cooling processes in industrial production, low-temperature cold energy generated during the unloading of refrigeration equipment, and low-temperature waste heat generated by data center server heat dissipation. If this waste cooling is not utilized, it will be directly discharged into the environment, resulting in energy waste.
[0003] Currently, the low-temperature waste cooling utilization technology mainly has the following problems: Most current low-temperature waste cooling utilization energy-saving and consumption-reducing devices pass cold water pipes through pipes that frequently need cooling, thereby cooling the water flow in the pipes. This results in a small heat exchange contact area and a large cold flow diameter, which cannot fully utilize the cold source at the center and affects utilization efficiency. Utility Model Content

Moreover, the small diameter diversion pipes can reduce the water flow diameter, allowing the internal residual heat to be fully utilized.
[0010] Preferably, in any of the above schemes, the branch pipes are arranged in a radial annular array around the center of the central branch pipe, and the length of the cylindrical heat dissipation fins is adapted to the length of the central branch pipe.

[0012] Preferably, in any of the above schemes, the two annular pipes, the several branch pipes, the several branch ducts, the several cylindrical heat dissipation fins, and the central branch pipe are all made of thermally conductive material.
[0013] The technical effects achieved by adopting the above scheme are as follows: the annular pipe can be stably supported by several supporting plates, thereby improving the stability of the support; the annular pipe made of heat-conducting material, several diversion pipes, several branch pipes, as well as several cylindrical heat dissipation fins and the central diversion pipe can improve the heat exchange efficiency.
[0014] This utility model has the following advantages:

[0023] As an optional technical solution of this utility model, both annular pipes 4 are concentrically arranged with the center of the inner wall of the cold source absorption pipe 1, and the diameter of the outer circle of the two annular pipes 4 is smaller than the diameter of the inner wall of the cold source absorption pipe 1, thereby reducing the influence of the annular pipes 4 on the water flow.
[0024] As an optional technical solution of this utility model, a plurality of diversion pipes 10 are arranged in a ring array around the center of two annular pipes 4. The diameter of the plurality of diversion pipes 10 is smaller than the diameter of the annular pipes 4 and the input pipe 5, so that the plurality of diversion pipes 10 can distribute and transport the residual heat evenly, improve the uniformity of heat exchange, and the small diameter of the diversion pipes 10 can reduce the water flow diameter, so that the internal residual heat can be fully utilized.
[0025] As an optional technical solution of this utility model, a number of branch pipes 9 are arranged in a radial annular array around the center of the central diversion pipe 8, and the distribution length of a number of cylindrical heat dissipation fins 7 is adapted to the length of the central diversion pipe 8, so that the number of branch pipes 9 are evenly distributed with equal spacing, thereby improving the uniformity of heat exchange.
[0026] As an optional technical solution of this utility model, the two annular pipes 4, several diversion pipes 10, several branch pipes 9, several cylindrical heat dissipation fins 7, and the central diversion pipe 8 are all made of heat-conducting material. Several supporting plates 3 are fixedly connected to the inner wall of the cold source absorption pipe 1. One side of the several supporting plates 3 is fixedly connected to the outer wall of the two annular pipes 4.

The heat-conducting material of the annular pipes 4, several diversion pipes 10, several branch pipes 9, several cylindrical heat dissipation fins 7, and the central diversion pipe 8 can improve the heat exchange efficiency.
[0027] This low-temperature waste cooling energy-saving and consumption-reducing device requires the following steps to be used:
[0028] 1) The residual coolant is injected into the annular pipe 4 through the input pipe 5. Through the annular pipe 4 and several branch pipes 10, the cold flow can be evenly dispersed through the interior of the cold source absorption pipe 1, so that the water flow is evenly dispersed and the cold source of the water flow can be more fully utilized.
[0029] 2) The heat exchange contact area can be greatly increased by several branch pipes 9 and several cylindrical heat dissipation fins 7, thereby improving the efficiency of heat exchange and the utilization of residual heat.
[0030] 3) After heat exchange, the water flows through the ring pipe 4 and several branch pipes 10 and is then output through the output pipe 6.
[0031] In summary, the annular pipe 4 and several branch pipes 10 can evenly disperse the cold flow through the interior of the cold source absorption pipe 1, making the water flow uniformly dispersed and allowing for better utilization of the cold source. Furthermore, the branch pipes 9 and several cylindrical heat dissipation fins 7 can significantly increase the heat exchange contact area, improve heat exchange efficiency, and enhance the utilization of residual cold. The annular pipe 4 and several branch pipes 10 can also increase the time for the cold flow to pass through the interior of the cold source absorption pipe 1, thereby increasing the heat exchange time and maximizing the absorption and utilization of residual cold.
