Description

TECHNICAL FIELD

[0001] The present application relates to a blind plate for blocking cold air installed in a server device and a processing method thereof. BACKGROUND

[0002] The cold aisle machine room is developed in response to "machine room energy saving and emission reduction, and promotion of green new machine room", and is mainly used for machine rooms with large heat dissipation, such as IDC data center machine rooms, to achieve the effect of accurately sending cold air. It is composed of two cabinet matrices. The traditional cold air of the machine room cannot be effectively controlled, and the cold air is randomly flowing, resulting in the feeling of "machine room like winter, cabinet like summer". The cold aisle machine room delivers all the cold air delivered to the cabinet interior to the heat dissipation equipment in the most economical and effective way, and the heat in the cabinet is delivered out of the cabinet along the designated direction. The blind plate is installed on the server cabinet and used as a baffle to prevent cold air leakage. The blind plate specifications include 1U, 2U, 3U, etc. (U refers to the internal effective use space of the cabinet, and the panel of the standard server cabinet is generally manufactured according to the NU specification). When the server cabinet in the machine room is not completely filled with equipment, the idle space is prone to cause cold air leakage, which cannot effectively control the cold air and cause waste. Therefore, the blind plate is designed to block the empty space to allow the cold air to pass through the equipment interior. In the prior art, the main part of the blind plate is generally processed by a metal plate, and the blind plate main body is fixed by a plastic handle, which can avoid screw fixing, is simple to operate, and is easy to install. Due to the rising labor cost, how to improve production efficiency is crucial to the survival of enterprises. However, the structure of the blind plate currently used has the following problems:

[0003] 1. Two-end rivet screw structure: the blind plate with this structure has low processing efficiency, requires one processing equipment and one worker, and has surface indentation due to the characteristics of the rivet, which is not aesthetic.

[0004] 2. Blind plate two-end bending positioning point structure: the blind plate with this structure also has low processing efficiency, and requires bending 6 times at both ends of one blind plate to complete, which can cause size deviation due to improper operation, resulting in defective products.

[0005] 3. Blind plate two-end welding positioning point structure: the blind plate with this structure also has low processing efficiency, size deviation, surface welding marks, and polishing treatment, which is more likely to cause product defects. SUMMARY

[0006] To solve the above problems, the application provides a new blind plate structure and a processing method, which adjusts the positioning points at both ends of the original blind plate body to the plastic handle, provides a mounting baffle for the plastic handle, matches the size of the plastic handle and the baffle, and no longer needs to process the positioning points at both ends of the blind plate body, and the blind plate body can adopt the automatic forming process of the general punch press, greatly improves the processing efficiency, reduces manual operation, and only one process can complete the original 2-3 processes, so that the blind plate body structure is simplified, the processing is more convenient, and the cost is reduced.
