Description

Technical Field

[0001] This invention relates to the field of electrical cabinet heat dissipation technology, and specifically discloses an electrical cabinet heat absorption and cooling device. Background Technology

[0002] Electrical cabinets are common electrical devices used to support and protect internal electronic components and switches. During prolonged operation, these components generate heat, causing the cabinet's interior temperature to rise. Typically, electrical cabinets use built-in cooling fans to draw in cool air from the bottom, which then flows upwards to dissipate heat. However, due to the numerous components of varying shapes and sizes within the cabinet, the incoming cool air cannot provide even cooling to all parts, resulting in poor heat dissipation and potential overheating and damage to components. Furthermore, for electrical cabinets operating in harsh environments (such as those in chemical plants where harmful gases are present in the surrounding air), blowing air into the cabinet using cooling fans can introduce harmful substances that accelerate component aging or damage. Therefore, traditional air-cooling methods are unsuitable for electrical cabinets operating in such harsh conditions. In view of the shortcomings of existing air-cooled heat dissipation methods for electrical cabinets, which cannot effectively and evenly dissipate heat from different components and are not suitable for electrical cabinets in harsh environments, this invention proposes an electrical cabinet adhesive heat absorption and cooling device that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0003] The present invention aims to provide an electrical cabinet heat absorption and cooling device to solve the problems that the existing air-cooled heat dissipation method for electrical cabinets cannot effectively and evenly dissipate heat from different components and is not suitable for electrical cabinets in harsh environments.

[0004] This invention is achieved through the following technical solution:

[0005] An electrical cabinet heat absorption and cooling device includes a rotating frame installed in the cabinet door. A drive motor is installed on the cabinet door to enable the rotating frame to rotate at a fixed angle. Several storage openings are evenly distributed on the outer side of the rotating frame. Each storage opening is provided with a heat-absorbing material filling frame, and the outer end of the heat-absorbing material filling frame is open. A telescopic drive component is provided on the rotating frame to push the heat-absorbing material filling frame out of the storage opening. A flexible partition is provided in the opening of the heat-absorbing material filling frame, and heat-absorbing mud is filled in the heat-absorbing material filling frame located inside the flexible partition.

[0006] This electrical cabinet-type heat absorption and cooling device cools the components inside the cabinet by placing a heat-absorbing material filling frame filled with heat-absorbing mud tightly against the components. The heat-absorbing mud, with its high plasticity and flexible layering properties, creates indentations that mirror the components. The components can then fully extend into these indentations, effectively absorbing the heat generated during operation and achieving a cooling effect. Furthermore, once the heat-absorbing mud has absorbed sufficient heat and reached its temperature, a drive motor rotates the frame at a fixed angle, allowing different heat-absorbing materials in the filling frames to be used for further heat absorption and cooling of the components.

[0007] As a further improvement to the above design, the cabinet door is provided with an air outlet and an air inlet at its upper and lower ends, respectively. A blower is located at the center of the lower end of the rotating frame, and an air vent is located at the upper end. Each heat-absorbing material filling frame has heat dissipation fins on its inner side facing the center of the rotating frame. This improved design allows cold air to flow along the heat dissipation fins after the heat-absorbing mud is switched, thereby removing heat from the heat-absorbing mud and ensuring rapid heat dissipation so that it can be put into the next cycle in a timely manner.

[0008] As a further feature of the above solution, a cooler is installed in the cabinet door located below the blower. This cooler can cool the cold air supplied by the blower, ensuring sufficient cooling effect on the heat-absorbing mud.

[0009] As a further feature of the above solution, the rotating frame is equipped with a partition, which divides the interior of the rotating frame into air-cooled zones corresponding to each heat-absorbing material filling frame. The heat dissipation fins are located in the corresponding air-cooled zones. This partition design allows each heat-absorbing material filling frame to have its heat dissipation fins positioned in an independent air-cooled zone. This ensures that when cold air is supplied by the blower, the cooling processes of multiple heat dissipation fins do not interfere with each other, allowing the heat-absorbing mud to be cooled independently by the cold air.

[0010] As a further feature of the above solution, the heat-absorbing material filling frame is equipped with a scraper that adheres to the outer surface of the flexible partition, and a push-pull rod connected to the scraper is provided at the lower end of the heat-absorbing material filling frame. The design of the scraper and push-pull rod allows the scraper to be moved up and down repeatedly by the push-pull rod during the heat absorption and cooling process for different components, thereby smoothing the working surface of the heat-absorbing mud to suit different components.

[0011] As a specific feature of the above solution, the push-pull rod is a telescopic push-pull rod; the design of the telescopic push-pull rod allows it to be stored away when there is no need to level it, without affecting the rotation switching of the rotating frame.

[0012] As a specific feature of the above scheme, the rotating frame is rectangular, and four storage openings are provided on the rotating frame, which are respectively located on the four sides of the rotating frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) The electrical cabinet bonding heat absorption and cooling device disclosed in this invention uses heat-absorbing clay as the heat-absorbing material. At the same time, it utilizes the plasticity of the heat-absorbing clay itself, so that the working surface of the heat-absorbing clay will be squeezed with the components inside the cabinet to create indentation marks, and the outer surface of the components will be completely bonded to the corresponding indentation marks. Therefore, during the long-term operation of the components, the heat generated by them can be effectively absorbed by the heat-absorbing clay, resulting in excellent and uniform cooling effect of the components. Moreover, the components inside the cabinet will not come into contact with harmful substances in the air, thereby effectively ensuring the service life of the components during long-term operation.

[0015] 2) In the process of absorbing heat and cooling down the electrical cabinet, the present invention also uses a rotating frame to switch different heat-absorbing mud to continuously absorb heat and cool down the components. At the same time, the heat-absorbing mud that is switched out can also achieve rapid dissipation of internal heat through the action of heat dissipation fins and cooling air, thereby ensuring that the heat-absorbing mud on the rotating frame can be repeatedly recycled.

[0016] 3) The present invention also provides a leveling mechanism in the heat-absorbing material filling frame. When different components need to be bonded for heat absorption and cooling, the working surface of the heat-absorbing mud can be leveled by scraping the scraper up and down. When different components are bonded together, the leveled heat-absorbing mud can re-create the corresponding marks on the working surface of the heat-absorbing mud and bond with it. Thus, the entire electrical cabinet bonding heat absorption and cooling device can be applied to various different components and has a wide range of applications. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments.

[0027] Example 1

[0028] Example 1 discloses an electrical cabinet bonding heat absorption and cooling device, see attached drawing. Figure 1 and attached Figure 2 The electrical cabinet includes a cabinet body 100 and a cabinet door 101. One side of the cabinet body 100 has an opening, and the cabinet door 101 is rotatably connected to the cabinet body 100 at the opening via a hinge. Various components 102 are installed on the inner wall of the cabinet body 100 facing the cabinet door 101.

[0029] Reference Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 6The fitting heat absorption and cooling device includes a rotating frame 201 installed in the cabinet door 101. The rotating frame 201 is rectangular in shape and has rectangular storage openings 202 on its four sides. Each rectangular storage opening is provided with a heat-absorbing material filling frame 203. The heat-absorbing material filling frame 203 is welded from heat-conducting metal plates and has an opening on its outward side. At the same time, multiple telescopic drive members 206 are provided at the outer end of each rectangular storage opening 202 of the rotating frame 201, and the telescopic drive members 206 are connected to the outer edge of the frame of the heat-absorbing material filling frame 203.

[0030] A flexible partition 204 is provided in the opening of the heat-absorbing material filling frame 203, and a large amount of heat-absorbing mud 205 is filled in the heat-absorbing material filling frame 203 inside the flexible partition 204, and the heat-absorbing mud 205 has good plasticity. When it is necessary to cool down the various components 102 on the inner wall of the cabinet 100, the heat-absorbing material filling frame 203 facing the inner wall of the cabinet 100 is pushed outward by the telescopic drive component 206, so that the flexible partition 204 comes into contact with the outer surface of the component 102. Then, under the continued pushing of the telescopic drive component 206, the flexible partition 204 and the heat-absorbing mud 205 will form a recessed mark 207 that is the same as the outer surface of the component 102 due to the squeezing action of the component 102. The recessed mark 207 will completely cover the component 102 and adhere to it. Through the action of the heat-absorbing mud, all the heat generated by the component 102 is absorbed away, thereby achieving the cooling effect of the component 102.

[0031] A rotary drive motor 208 is installed on the upper surface of the cabinet door 101, and the output shaft of the rotary drive motor 208 is connected to the center of the upper end of the rotating frame 201. After the heat-absorbing mud 205 absorbs heat and cools the component 102 for a period of time, the heat-absorbing material filling frame 203 is first retracted into the rectangular storage opening 202 by the action of the telescopic drive component 206. Then, the rotary drive motor 208 is started to control the rotating frame 201 to rotate 90°, so that another heat-absorbing material filling frame 203 is set towards the component 102 on the inner wall of the cabinet 100. Finally, under the action of the telescopic drive component 206, another set of flexible partitions 204 and heat-absorbing mud 205 are pressed onto the component 102 to form a recessed mark 207, thereby continuing to absorb heat and cool the component 102.

[0032] Example 2

[0033] Example 2 discloses an electrical cabinet bonding heat absorption and cooling device for effectively dissipating heat from heat-absorbing mud 205, based on Example 1. The similarities between Example 2 and Example 1 will not be repeated here; the differences are as follows:

[0034] Reference Appendix Figure 1 ~Appendix Figure 6 In this embodiment 2, air vents 103 and air inlets 104 are respectively provided at the upper and lower ends of the cabinet door 101. A cooler 200, which can be a semiconductor cooler, is installed on the bottom wall of the cabinet door 101 below the rotating frame 201. A blower 212 is located at the lower center of the rotating frame 201, facing the cooler 300. An air vent 209 is located at the upper end of the rotating frame 201, and a rotary drive motor 208 is connected to the air vent 209. Heat dissipation fins 210 are provided on the inner side of each heat-absorbing material filling frame 203 facing the center of the rotating frame 201. The heat dissipation fins 210 are vertically arranged, allowing the cold air delivered by the blower 212 to flow up and down along the gaps between the heat dissipation fins 210, thereby carrying away the heat from the heat-absorbing mud 205.

[0035] In addition, in order to ensure that the incoming cold air has an independent heat dissipation effect on the heat-absorbing mud 205 in each heat-absorbing material filling frame 203, an X-shaped partition 211 is also provided inside the rotating frame 201. The partition 211 can form four independent air-cooling zones inside the rotating frame 201. When the heat dissipation fins 210 on the back of the heat-absorbing material filling frame 203 extend into the corresponding air-cooling zone, the heat-absorbing mud 205 can be independently cooled by the cold air.

[0036] Example 3

[0037] Example 3 discloses a leveling mechanism based on Example 2, which adds a set of functions to automatically level the heat-absorbing mud 205 in the heat-absorbing material filling frame 203 and restore it to its initial state so as to achieve full utilization.

[0038] The similarities between Example 3 and Example 2 will not be repeated here; the differences are detailed in the appendix. Figure 7 In this embodiment, a scraper 300 is provided in the heat-absorbing material filling frame 203 outside the flexible partition 204, and the scraper 204 is set in close contact with the outer surface of the flexible partition 204. At the same time, a push-pull rod 301 is inserted into the heat-absorbing material filling frame 203 below the scraper 300. The push-pull rod 301 can be designed to be telescopic for easy storage without affecting the rotation of the rotating frame 201, and the upper end of the push-pull rod 301 is connected to the scraper 300.

[0039] When the components 102 on the inner wall of the cabinet 100 are modified or other components 102 are added, the operator can open the cabinet door 101 and use the push-pull rod 301 to make the scraper 300 scrape up and down several times, thereby smoothing the outer end of the heat-absorbing mud in the heat-absorbing material filling frame 203, so as to be suitable for the bonding and heat absorption of the components 102 on the inner wall of the modified or added cabinet 100, making its application range wider.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
