Science and design of handle for low-temperature storage freezer

In our daily life, refrigerator is a common household appliance, and the low-temperature storage freezer is one of the indispensable facilities in scientific research, medical treatment and other fields. These devices can not only provide a safe and stable storage environment for biological samples, but also ensure that the freshness and quality of food are not damaged. Among these devices, there is a seemingly inconspicuous but very important accessory-freezer handle.

1, material selection

For low-temperature storage freezers, the internal temperature is generally kept below minus 20℃, or even as low as minus 86℃. Therefore, factors such as cold resistance and compression resistance should be considered when selecting the handle material. At present, several common handle materials on the market include ABS plastic, stainless steel, aluminum alloy and so on.

Among them, ABS plastic has good toughness and strength, and the cost is relatively low; Stainless steel has excellent corrosion resistance and aesthetics; Aluminum alloy has the advantages of portability and durability. Selecting the most suitable materials according to different application scenarios and requirements can ensure the stability and reliability of the freezer handle after long-term use.

2. Structural design

In addition to the material, the structure is also one of the key factors affecting the functional effect of the handle. Generally speaking, the door handle of a low-temperature storage freezer is mainly composed of a handle part and a connecting part. Among them, the handle part is the place where the user directly contacts, so its shape should conform to the principle of ergonomics, which is convenient for holding and reduces the fatigue of hands. Meanwhile, in the coldThe flexibility of fingers decreases in the environment, and the design that is too small or too complicated will increase the difficulty of operation.

In addition, in order to prevent energy waste caused by cold air leakage or frost caused by ambient air condensation, it is necessary to set a sealing ring with appropriate size and position to enhance the sealing performance.

3. Installation method

Finally, let's take a look at the installation problems. Usually, there are two basic forms: fixed and movable. The former is suitable for those situations where there is plenty of space and it needs to be opened and closed frequently (such as supermarket cold storage); The latter is more flexible and convenient (such as household refrigerators). Of course, it should be considered in combination with the actual situation.

It is worth mentioning that in order to avoid the damage of parts and components caused by long-term exposure to extreme temperature conditions, special treatments such as electroplating anti-corrosion coatings are needed in the production process.

Summary:

To sum up, although it is only a small "freezer" handle, it carries many important tasks, and every link from material selection to processing must be strictly controlled to meet the growing needs of users. I hope that in the future, with the continuous progress of technology, more innovative design schemes can be brought, so that we can enjoy a better life experience!
