Description

Technical Field

[0001] The present invention belongs to the technical field of air-conditioning cabinets in a data center computer room, and in particular relates to a novel pull-out structure for an electrical box of an inter-row air-conditioning and refrigeration system. Background Art

[0002] Data centers have become the glue that holds modern society together. Whether we're making a purchase with a credit card, messaging a friend, or ordering a pizza, virtually everything we do every day is powered by data centers. These advancements are driven by the ever-increasing demands of businesses and consumers. This has necessitated a significant increase in the processing power and capacity that data centers must provide. Soon, the demand for server processing power led to the emergence of third-party providers. To sustain such heavy loads in computer rooms, environmental considerations have become paramount. In-row air conditioners, with optional configurations suitable for large, medium, and small computer rooms, offer high energy efficiency, ease of operation, and convenient maintenance.

[0003] Interrow air conditioners are placed between rows of server cabinets, close to the heat source to dissipate heat directly. Because they are close to the heat source, the return air temperature of the air conditioner is high, making its energy efficiency ratio very good. However, the width of the interrow air conditioner is relatively narrow, and there are also very high requirements for the debugging and installation inside the unit. Summary of the Invention

[0004] Purpose of the invention: In view of the above-mentioned existing problems and shortcomings, the purpose of the present invention is to provide a pull-out structure for the electrical box of the inter-row air-conditioning and refrigeration system, which is suitable for the combined use of multiple micro-modules in large data centers, and solves the problems of difficult front-end operation, small space and difficult maintenance during on-site installation and debugging.

[0005] Technical Solution: To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a pull-out structure for an electrical box of an inter-row air-conditioning and refrigeration system, applied to an inter-row air-conditioning cabinet, characterized in that it includes a fixed support member, a slide rail, a sliding member, and a limit member, wherein the fixed support member is a long strip of metal plate, the long strip of metal plate including a main body and right-angled edges formed by bending in the same direction on both sides of the main body, a gap being left between the right-angled edges and the main body, and the right-angled edges being fixed to the air-conditioning cabinet by bolts;

[0006] The slide rail is formed by bending two sides of a long metal plate at right angles to form an upward-facing stop bar and a downward-facing fixed portion, respectively. The fixed portion of the slide rail is fixedly connected to the back of the fixed support member, and the stop bar and the back of the fixed support member form a slide groove.

[0007] The sliding member is formed by bending two sides of a metal strip at right angles in the same direction to form a mounting bent edge and a sliding bent edge respectively. The sliding bent edge is embedded in the slide groove and can move horizontally in the slide groove. Both ends of the sliding member are also provided with upward right-angled bent edges as baffles. The mounting bent edge is used to fix the electrical box body.

[0008] The limiting member is fixed on the top of the fixed support member and is located between the baffles at both ends of the sliding member, and can play a limiting role.

[0009] Preferably, the upper end of the stop bar of the slide rail is further provided with an inwardly inclined sloped edge, and the height of the edge is higher than the sliding bent edge of the sliding member.

[0010] Preferably, the top of the installation bent edge of the sliding member is connected to the electrical box through an angle steel connector.

[0011] Preferably, the gaps between the right-angled bent edges on the upper and lower sides of the fixed support and the main body are different in size.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0013] (1) In the past, the electrical box was pulled out using ball guide rails for sliding. This case uses the bending method of sheet metal parts, and the friction between parts generates sliding. The process installation is simple and only screws and rivets are used for pulling, which is relatively simple to implement.

[0014] (2) An electrical box assembly requires two ball guide rails. The hardware structure is complex and difficult to disassemble and assemble. It needs to be disassembled into two parts during installation, one part installed on the electrical box and the other part installed on the frame sheet metal. The electrical box is assembled in the electrical workshop, and the frame is assembled in the frame workshop. This requires transportation back and forth between the two workshops, and it is difficult to coordinate in terms of space. In this case, only three sheet metal parts need to be bent, which is low-cost and can be completed in the frame workshop.

[0015] (3) In the existing technology, the cost of two ball guide rails is about 30 yuan. Excluding the common parts (sheet metal fixed to the frame), the cost in this case is about 20 yuan, saving about half the price. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0021] The present invention is further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0022] like Figure 1-4 As shown, the electrical box pull-out structure of the row-level air-conditioning and refrigeration system of the present invention is mainly used for internal debugging and installation of row-level air-conditioning cabinets, and is particularly suitable for the situation where the adjustment width is narrow.

[0023] The electrical box pull-out structure of the inter-row air-conditioning refrigeration system of the present invention mainly includes a fixed support member, a slide rail, a sliding member and a limit member, wherein:

[0024] The fixed support is a long metal plate with a main body and two right-angled edges bent in the same direction on both sides of the main body. A gap is left between the right-angled edges and the main body, and the right-angled edges are fixed to the air conditioning cabinet with bolts. The gaps between the right-angled edges and the main body on the upper and lower sides of the fixed support vary in size, allowing it to accommodate a wider range of electrical boxes and electrical component mounting plates.

[0025] The slide rail is constructed from a long metal plate, with two sides bent at opposite right angles to form an upward-facing stop bar and a downward-facing fixed portion. The fixed portion of the slide rail is fixedly connected to the back of the fixed support, and the stop bar and the back of the fixed support form a sliding groove. Furthermore, to prevent the sliding member from detaching during sliding, the upper edge of the slide rail's stop bar is tilted inward, facilitating disassembly while ensuring it remains attached. The stop bar is also ensured to be 1-2 cm higher than the sliding member.

[0026] The slider is constructed from a long metal strip with two sides bent in the same direction at right angles to form a mounting bend and a sliding bend, respectively. The sliding bend is embedded in the chute and can move horizontally within the chute. Both ends of the slider are also provided with upwardly directed right-angled bends as baffles. The mounting bend is used to secure the electrical box. Preferably, the top of the mounting bend of the slider itself is connected to the electrical box via an angle steel connector.

[0027] The limiting member is fixed on the top of the fixed support member and is located between the baffles at both ends of the sliding member. The translation stroke of the sliding member is the distance between the two baffles, thereby playing a limiting role.

[0028] Compared with the existing technology, the present invention utilizes the sliding between sheet metals to achieve the pull-out of the electric control box components, and then can be maintained from the front, which greatly solves the problems caused by the space layout on site.

[0029] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and technical concepts of the present invention, should be covered by the scope of protection of the present invention.
