Description

Technical Field

[0001] This invention relates to the field of temperature impact test chamber technology, and specifically to a connecting frame device that can prevent frost formation. Background Technology

[0002] High and low temperature impact test chambers are divided into three-chamber and two-chamber types according to testing requirements and standards. The difference lies in the testing method and internal structure. The three-chamber type consists of a cold storage chamber, a heat storage chamber, and a test chamber; the product is placed in the test chamber during testing. The two-chamber type consists of a high-temperature chamber and a low-temperature chamber, and the switching between high and low temperatures is achieved by a motor-driven basket movement; the product is placed in the basket and moves with it. It is used to test the degree to which material structures or composite materials can withstand continuous exposure to extremely high and low temperatures in a short time, allowing for the detection of chemical changes or physical damage caused by thermal expansion and contraction of the sample in the shortest possible time.

[0003] In the two-compartment basket-type impact chamber, the high-temperature chamber and the low-temperature chamber are equipped with doors. Multiple layers of sealing strips are installed at the doors of both chambers to prevent heat exchange between the interior and the outside environment. The doors of both chambers are secured with U-shaped metal plates to maintain the multiple sealing strips, ensuring a sealed environment and preventing heat loss when the doors are closed. However, after the test, when the cold chamber is opened, frost is observed on the metal plates near the sealing strips. This condensation of atmospheric water vapor at this point affects the impact test results. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a connecting frame device that can prevent frost formation.

[0005] The present invention provides a connecting frame device capable of preventing frost formation, comprising: A high-temperature chamber opening frame is installed at one of the chamber openings of the high-temperature chamber. The low-temperature chamber opening frame is installed at the two openings of the low-temperature chamber. The high-temperature chamber frame and the low-temperature chamber frame are connected to each other to form an integrated H-shaped connecting frame.

[0006] Furthermore, the four corners of the integrated H-shaped connecting frame are rounded.

[0007] Furthermore, the upper hole of the integrated H-shaped connecting frame matches the opening of the high-temperature chamber.

[0008] Furthermore, the lower hole of the integrated H-shaped connecting frame matches two points on the opening of the low-temperature chamber.

[0009] Furthermore, the integrated H-shaped connecting frame is provided with an H-shaped inner cavity that matches its shape.

[0010] Furthermore, the integrated H-shaped connecting frame is made of metal.

[0011] The beneficial effects of this invention are as follows: The connecting frame device described in this invention can prevent frost formation. It connects the high-temperature chamber and the low-temperature chamber at the sealing strip installation point by using a connecting frame. In this way, after the test is completed, the high temperature and low temperature are neutralized by the metal plate of the connecting frame, preventing the low temperature from being transmitted to the metal plate near the chamber door and causing frost formation.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0015] like Figures 1-3 As shown, the connecting frame device that can prevent frost formation described in this specific embodiment includes a high temperature chamber opening frame 11 set at the opening 31 of the high temperature chamber 3 and a low temperature chamber opening frame 12 set at the opening 41 of the low temperature chamber 4. The high-temperature chamber frame 11 and the low-temperature chamber frame 12 are connected to each other to form an integrated H-shaped connecting frame 1.

[0016] Furthermore, the four corners of the integrated H-shaped connecting frame 1 are rounded.

[0017] Furthermore, the upper hole 13 of the integrated H-shaped connecting frame 1 is matched with the opening 31 of the high-temperature chamber 3.

[0018] Furthermore, the lower hole 14 of the integrated H-shaped connecting frame 1 is matched with the opening 41 of the low-temperature chamber 4.

[0019] Furthermore, the integrated H-shaped connecting frame 1 is provided with an H-shaped inner cavity 15 that matches its shape.

[0020] Furthermore, the integrated H-shaped connecting frame 1 is made of metal.

[0021] The working principle of this invention is as follows: like Figure 4 As shown, this design innovates upon the traditional two-compartment impact test chamber 2, specifically addressing the condensation phenomenon that occurs at the low-temperature chamber 4. The high-temperature chamber 3 and the low-temperature chamber 4 are arranged vertically to form a high-low temperature test chamber. Guide rails are installed inside the test chamber, and baskets 5 are mounted on these rails, with the product to be tested placed on the baskets 5. A control room 6 is located on one side of the high-low temperature test chamber.

[0022] In this design, the high-temperature chamber 3's opening 31 and the low-temperature chamber 4's opening 41 are respectively equipped with a high-temperature chamber opening frame 11 and a low-temperature chamber opening frame 12. Traditionally, the high-temperature chamber opening frame 11 and the low-temperature chamber opening frame 12 are separate units, not connected. This results in the temperature of the high-temperature chamber opening frame 11 not being transferred to the low-temperature chamber opening frame 12. Consequently, the measurement results of the product under test on the basket 5 in the two-compartment impact test chamber 2 are inaccurate when the basket 5 moves up and down.

[0023] like Figures 1-3 As shown, to solve the above problems while considering cost control, an integrated H-shaped connecting frame 1 is formed by connecting the high-temperature chamber frame 11 and the low-temperature chamber frame 12. Furthermore, the integrated H-shaped connecting frame 1 is made of metal. This allows the high and low temperatures to neutralize each other through the integrated H-shaped connecting frame 1 (metal plate) after the test, preventing the low temperature from being transferred to the metal plate near the chamber door and causing frost formation.

[0024] In this design, to further improve the utilization of heat from the high-temperature chamber to neutralize the temperature in the low-temperature chamber, an integrated H-shaped connecting frame 1 is incorporated with a H-shaped inner cavity 15 that matches its shape. This allows heat from the high-temperature chamber to penetrate into the H-shaped inner cavity 15, and cold air from the low-temperature chamber to also penetrate into the H-shaped inner cavity 15, thus achieving rapid neutralization. Furthermore, the integrated H-shaped connecting frame 1 is made of stainless steel; the metal plate itself can neutralize due to the material's thermal conductivity, greatly improving the efficiency of temperature neutralization and ensuring that frost does not form on the metal plate of the low-temperature chamber's sealing strip.

[0025] In this design, the surface of the integrated H-shaped connecting frame 1 can be provided with several mounting screw holes, so as to facilitate fixing it to the high temperature chamber 3 and low temperature chamber 4 of the two-compartment impact test chamber 2 with screws.

[0026] In this design, to address the problems existing in the two-compartment impact test chamber 2, the high-temperature chamber opening frame 11 and the low-temperature chamber opening frame 12 are simply connected to each other to form an integrated H-shaped connecting frame 1. The integrated H-shaped connecting frame 1 is still made of stainless steel, which solves the condensation phenomenon of the metal plate at the low-temperature chamber. The modification cost is low, but it effectively solves the practical problem and improves the measurement accuracy and efficiency.

[0027] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made in accordance with the features and principles described in the claims of this patent application are included in the scope of this patent application.
