Description

Technical Field

[0001] This invention relates to the field of heat dissipation component technology, specifically to an externally finned passive heat pipe. Background Technology

[0002] Finned tubes are a type of heat exchange element. To improve heat exchange efficiency, fins are typically added to the surface of the heat exchange tube to increase its outer (or inner) surface area, thereby improving heat exchange efficiency.

[0003] Currently, some finned tubes on the market have heat pipes and fins that are set separately. The fins are connected to the heat pipe by welding or other connection methods. In some finned tubes, the heat pipe and fins are made of different materials, which can easily cause corrosion due to different metal potential differences or crevice corrosion. Moreover, most heat pipes on the market are connected by clamps or flanges, which are inconvenient to position during installation, difficult to disassemble, have poor stability, and affect maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide an externally finned passive heat pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an external finned passive heat pipe, comprising a passive heat pipe assembly and a mounting assembly disposed at the end of the passive heat pipe assembly.

[0006] The passive heat pipe assembly includes a heat pipe body and heat dissipation fins disposed on the outer side of the heat pipe body. Several positioning keys are evenly distributed at the end of the heat pipe body, each with a first slot and a locking screw hole inside the first slot. The heat dissipation fins and heat pipe body provide heat dissipation. The positioning keys are used to restrain the passive heat pipe assembly during installation, and the locking screw hole is used to engage bolts to lock the passive heat pipe assembly in place. Passive heat pipes eliminate the need for water pumps, compressors, and other power sources, thus significantly reducing costs.

[0007] The installation assembly includes a tube, a retaining plate, and a base plate. The inner side of the tube has several positioning grooves that mate with the positioning keys, and the outer side of the tube has several connecting grooves. A second retaining groove is formed between the positioning grooves and the connecting grooves. The retaining plate is set in the connecting groove and its end is hinged to the connecting groove. The retaining plate is provided with a retaining block, which is engaged in the corresponding first retaining groove and second retaining groove. The retaining block has a connecting hole, which is aligned with the locking screw hole and fixed by bolts.

[0008] By inserting the end of the heat pipe body with the positioning key into the insert and cooperating the positioning key with the positioning groove, the limiting effect is achieved. The heat pipe body is initially positioned and fixed by locking the card block on the card plate in the first card slot and the second card slot, so that it can be locked with bolts.

[0009] As a preferred embodiment of the present invention, one or more external finned passive heat pipes are provided, and the multiple external finned passive heat pipes are arranged in an array, including a rectangular array, a circular array, or a concentric circle array, and the array arrangement can be determined according to the actual situation.

[0010] Preferably, the heat dissipation fins are provided with one or more segments, including two or three segments, and each segment includes three heat dissipation fins. The number of segments can be customized according to requirements, and the quantity of each segment can also be customized according to requirements.

[0011] As a preferred embodiment of the present invention, the heat pipe body includes a straight shape, a U-shape, an S-shape, or an annular shape, and the shape of the heat pipe body can also be changed according to requirements.

[0012] As a preferred embodiment of the present invention, the shape of the heat dissipation fins includes a disc shape or a spiral shape, and the shape of the heat dissipation fins can also be customized according to requirements.

[0013] In a preferred embodiment of the present invention, both the heat pipe body and the heat dissipation fins are made of copper, and the heat pipe body and the heat dissipation fins are integrally formed. This integral forming eliminates corrosion due to different metal potential differences, crevice corrosion due to non-circularity, assembly thermal resistance between different parts, and avoids loosening caused by thermal shock due to differences in the thermal expansion coefficients of different materials. This significantly improves reliability and extends product lifespan.

[0014] As a preferred embodiment of the present invention, a fixing hole is provided at the corner of the base plate, and the fixing hole is used to fix the mounting component to the wall or other equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In summary, this invention integrates the heat pipe body and heat dissipation fins into a single unit, eliminating corrosion due to different metal potential differences, preventing crevice corrosion caused by non-circularity, and avoiding loosening due to thermal shock caused by different thermal expansion coefficients of the materials. The positioning key and positioning groove work together to achieve a limiting effect. The heat pipe body is initially positioned and fixed by engaging the locking blocks on the locking plate within the first and second locking grooves, facilitating installation.
