Description

Technical Field

[0001] This utility model relates to the field of heat dissipation cabinet technology, specifically a heat pipe heat dissipation cabinet. Background Technology

[0002] A heat dissipation cabinet is a cabinet used to house and dissipate heat from heat-generating components. With the development of technology, the waterproof and dustproof ratings of server racks are getting higher and higher. However, the enclosed environment of a server rack can lead to poor heat dissipation, especially when the rack contains high-performance and high-power electrical components. Prolonged operation at high temperatures can significantly shorten the lifespan of electrical components and reduce their operational stability.

[0003] For example, the utility model application with application number CN202222802122.5 discloses a heat dissipation cabinet. The heat dissipation cabinets similar to the above application still have the following shortcomings: they usually use cold airflow to dissipate heat from heat-generating devices. In order to promote airflow, a power structure is required, which consumes a lot of energy.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a heat pipe cooling cabinet. Utility Model Content

[0005] The purpose of this invention is to provide a heat pipe cooling cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat pipe cooling cabinet, comprising a cabinet body and a heat pipe body, wherein a heating chamber is provided on the lower side of the cabinet body and a well-sealed cooling chamber is provided on the upper side of the cabinet body, a partition is fixed between the heating chamber and the cooling chamber, and circular grooves are equally spaced inside the partition, and heat pipe bodies are installed inside each of the circular grooves, with the upper and lower sides of the heat pipe body located inside the cooling chamber and the heating chamber, respectively, and the heat pipe body is a hollow tube with closed upper and lower ends.

[0007] Furthermore, the heat pipe body includes a heat absorption section and a transition section, which are arranged sequentially from bottom to top, and the interior of the transition section is filled.

[0008] Furthermore, the heat pipe body also includes a heat dissipation section, the upper side of the heat pipe body is configured as the heat dissipation section, and the heat dissipation section is located inside the heat dissipation chamber.

[0009] Furthermore, cooling medium inlets and outlets are provided on both the left and right sides of the cabinet, and heat dissipation fins penetrate the upper side of the heat dissipation chamber.

[0010] Furthermore, a heating device is installed inside the heating chamber, and the heating device is located between two adjacent sets of heat pipe bodies.

[0011] This utility model provides a heat pipe cooling cabinet, which has the following beneficial effects:

[0012] This invention features a heat pipe body installed inside a circular groove in a partition, penetrating both the heating chamber and the heat dissipation chamber of the cabinet. This allows the heat-absorbing section of the heat pipe body to adhere to the surface of the heating element in the heating chamber, absorbing heat and promoting the heat absorption of the heat pipe fluid within the heat-absorbing section. The heat then vaporizes and rises to the heat dissipation chamber, where the heat dissipation section of the heat pipe body dissipates heat, effectively controlling the operating temperature of the heating element. Furthermore, the heat generated by the heating element is contained within the heat dissipation chamber and carried away by the heat dissipation medium, minimizing heat loss to the external environment. The entire heat transfer process requires no power. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1-2 As shown, a heat pipe cooling cabinet includes a cabinet body 1 and heat pipe bodies 6. A heating chamber 2 is provided on the lower side of the interior of the cabinet body 1, and a well-sealed heat dissipation chamber 3 is provided on the upper side of the interior of the cabinet body 1. A partition 4 is fixed between the heating chamber 2 and the heat dissipation chamber 3, and circular grooves 5 are equally spaced inside the partition 4. Heat pipe bodies 6 are installed inside each of the circular grooves 5, and the upper and lower sides of the heat pipe bodies 6 are located inside the heat dissipation chamber 3 and the heating chamber 2, respectively. A heating element 9 is installed inside the heating chamber 2, and the heating element 9 is located between two adjacent sets of heat pipe bodies 6. The heat pipe bodies 6 and the circular grooves 5 can be arranged in multiple sets according to the size of the cabinet body 1. The heat pipe bodies 6 are installed inside the circular grooves 5 of the partition 4 and penetrate the heating chamber 2 and the heat dissipation chamber 3 of the cabinet body 1, so that the heat absorption section 601 of the heat pipe body 6 can adhere to the surface of the heating element 9 in the heating chamber 2 to absorb heat.

[0019] like Figures 1-3 As shown, the heat pipe body 6 is a hollow tube closed at both ends. The heat pipe body 6 includes a heat absorption section 601 and a transition section 602. The heat pipe body 6 is arranged from bottom to top as the heat absorption section 601 and the transition section 602, and the interior of the transition section 602 is filled. The heat pipe body 6 also includes a heat dissipation section 603. The upper side of the heat pipe body 6 is set as the heat dissipation section 603, and the heat dissipation section 603 is located inside the heat dissipation chamber 3. Cooling medium inlet and outlet 8 are provided on both the left and right sides of the cabinet 1. Heat dissipation fins 7 penetrate through the upper side of the heat dissipation chamber 3. After the heat absorption section 601 absorbs heat, it can vaporize and rise to the heat dissipation chamber 3 through the heat pipe liquid in the heat pipe body 6, so that the heat dissipation section 603 of the heat pipe body 6 dissipates heat, thereby effectively controlling the working temperature of the heating device 9, and controlling the heat generated by the heating device 9 within the heat dissipation chamber 3, and then carrying it away through the heat dissipation medium. There is little heat dissipation to the outside environment, and the entire heat transfer process does not require power.

[0020] In summary, as Figures 1-3 As shown, in use, the heat pipe cooling cabinet first installs the heating element 9 inside the heating chamber 2 of the cabinet 1, so that the heat pipe body 6 is installed inside the circular groove 5 of the partition 4 and passes through the heating chamber 2 and the heat dissipation chamber 3 of the cabinet 1. At this time, the heat absorption section 601 of the heat pipe body 6 can adhere to the surface of the heating element 9 in the heating chamber 2 to absorb heat, and then the heat pipe liquid in the heat pipe body 6 vaporizes and rises to the heat dissipation chamber 3, and dissipates heat through the heat dissipation section 603 of the heat pipe body 6, thereby effectively controlling the working temperature of the heating element 9 and controlling the heat generated by the heating element 9 within the heat dissipation chamber 3, and then carrying it away through the heat dissipation medium. There is little heat dissipation to the outside environment, and the entire heat transfer process does not require power. This completes the use process of the heat pipe cooling cabinet.

[0021] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
