All evaporative tubes of high-quality freezers are made of high-quality copper coils and processed into wide-faced special shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is uniform. The appropriate thickness can not only ensure a long service life, but also make the appearance of the freezer smooth and strong. Compared with aluminum pipes or composite pipes, copper pipes have a better cooling effect and better corrosion resistance. High-quality copper coils have the advantages of high cleanliness in the pipes and fewer pipe joints, which can effectively prevent leakage or blockage in the refrigeration system. The round tube is processed into a rectangle so that the contact between the evaporation tube and the cooling liner changes from point contact to surface contact, which expands the transfer area and speeds up the cooling speed.

    The more obvious features of high-quality refrigerators:

  (1) Good thermal insulation performance

    The one-piece foam of the freezer and the solid and solid steel frame foundation make the cabinet body better heat preservation performance and the structure is more durable.

  (2) Strong corrosion resistance

    The color steel cabinet inner tank with strong corrosion resistance increases the service life of the cabinet.

   (3) Good display effect

    The fully transparent glass side panel of the freezer makes the items in the cabinet clear at a glance and enhances the display effect of the items in the cabinet.
