Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a dual-core copper tube copper fin heat sink. Background Technology

[0002] Tube-finned heat exchangers are the most widely used heat exchange equipment in gas-liquid heat exchangers. They enhance heat transfer by adding fins to ordinary base tubes. The base tubes can be steel tubes, stainless steel tubes, copper tubes, etc., and the fins can be steel strips, stainless steel strips, copper strips, aluminum strips, etc. Compared with finned tube heat exchangers made of other materials, copper tube copper finned heat exchangers have won the favor of many customers due to their superior thermal performance characteristics. In the copper tube and copper fin heat exchanger manufacturing industry, single-core heat exchangers are currently the most commonly used in China. However, although single-core heat exchangers can meet the thermal performance requirements under most operating conditions, some customers have limited site space, equipment transportation restrictions, and power consumption limitations for operating heat dissipation equipment. As a result, single-core heat exchangers cannot simultaneously meet the requirements for size, transportation, and energy consumption. Therefore, the above problems need to be improved. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-core copper tube and copper fin heat sink.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a dual-core copper tube copper fin radiator, comprising an air intake chamber, an air intake mechanism installed inside the air intake chamber, a first heat dissipation chamber installed at the rear end of the air intake chamber, a second heat dissipation chamber installed at the rear end of the first heat dissipation chamber, heat dissipation mechanisms installed inside the first and second heat dissipation chambers, and a base plate installed at the bottom of the first and second heat dissipation chambers, with a U-shaped connecting pipe installed inside the base plate, and filters installed at the front end of the air intake chamber and the rear end of the first heat dissipation chamber.

[0005] Preferably, the air intake mechanism includes a mounting rod installed inside the air intake chamber and an air intake fan installed at the rear end of the mounting rod. A first transmission wheel is installed at the shaft of the air intake fan. The first transmission wheel is located at the front end of the mounting rod. A second transmission wheel is installed at the lower end of the mounting rod. A transmission belt is sleeved on the outer side of the first transmission wheel and the second transmission wheel.

[0006] Preferably, the transmission belt has a triangular cross-section, a drive assembly is installed on the inner side of one end of the transmission belt, and a reserved groove for installing the drive assembly is provided on the filter screen at the front end.

[0007] Preferably, the heat dissipation mechanism includes two sets of symmetrical first finned tubes installed inside the first heat dissipation chamber and a second finned tube installed inside the second heat dissipation chamber. The upper ends of the two first finned tubes are respectively equipped with a first filling port and a second filling port. The bottom ends of the two first finned tubes are each equipped with a drain pipe, and the bottom end of the second finned tube is equipped with a third filling port. The top end of the second finned tube is equipped with a drain pipe.

[0008] Preferably, both drain pipes and the third filling port are located inside the bottom plate, and one end of each drain pipe and the third filling port are respectively connected to both ends of the U-shaped connecting pipe.

[0009] Preferably, clamps are fitted at one end of the drain pipe and at the connection between the third filling port and the U-shaped connecting pipe, at the connection between the first finned tube and the first filling port and the second filling port, and at the connection between the second finned tube and the third filling port and the drain pipe. A reinforcing bolt is hinged to one end of the clamp, and the other end of the reinforcing bolt is inserted into the other end of the clamp.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The series connection structure of the first and second finned tubes allows for adjustments to smaller height and width dimensions to achieve the same heat dissipation performance, thereby reducing the size of the device. This avoids the high transportation costs caused by the size limitations of standard containers, meets installation requirements under specific working conditions, facilitates transportation, and reduces transportation costs. Furthermore, the "counter-flow" trend between the first and second filling ports and the drain pipe and the air intake fan direction allows for a larger contact area between the heat dissipation fins and the air, thus improving heat exchange efficiency, reducing heat dissipation power consumption, and saving energy and protecting the environment. Ultimately, this solves the problems of high transportation costs and high energy consumption during operation caused by the excessive size of existing devices. Attached Figure Description

[0015] In this invention, the heat dissipation mechanism includes two sets of symmetrical first finned tubes 10 installed inside the first heat dissipation chamber 2 and second finned tubes 11 installed inside the second heat dissipation chamber 3. The first finned tubes 10 and second finned tubes 11 facilitate heat exchange with the air. The upper ends of the two first finned tubes 10 are respectively equipped with a first filling port 12 and a second filling port 13, facilitating the addition of coolant.
