Application of constant force spring in refrigerator door

source:Qianye Precision time:2022-9-14

In order to make the refrigerator operate effectively, the door should be kept closed. Keep the door open for a short time when putting or taking out food. However, opening it for a long time will affect its cooling and endanger food safety. It will also lead to excess power consumption. Fortunately, the modern refrigerator door can be added with a constant force spring to automatically close after you open the refrigerator for use. Nowadays, this kind of design is relatively rare in the market. It is generally a magnetic refrigerator door, which explains why the magnet is attached to it.

  We have seen that it is essential to keep the refrigerator door closed all the time. If the door remains open for a long time, it will counteract the internal temperature balance and affect the quality of the food stored in it.When this situation continues for a long time, the compressor cannot maintain a low internal temperature. This undermines its operational efficiency. In addition, the longer the door is opened, the hotter the inside of the refrigerator will become.
  Because it is very important to keep the door closed, a constant force spring is added to the refrigerator door. If you open them, they will close automatically.constant force spring is added, which pulls the door back and seals it tightly to the frame when the door is opened. Constant force springs are often the best spring type for this application and can be manipulated in a number of ways to ensure your design works. Constant force springs are characterized by a large output force with little space requirement, applying an almost constant force throughout the stretch. The constant force spring also has the characteristics of short initial preload, that is, it can withstand the rated load at short elongation, and provide long elongation capability.


In terms of the design and development of constant force springsQianye precision has many successful cooperation projects. These constant force springs are special-purpose components in customers’ new product institutions. Qianye can carry out detailed design according to the main design intention, including the selection of part materials, the connection mode and size of parts.
