Embodiment Construction

[0022] The material of the fixing strip of the evaporator of the low-temperature cabinet of the present invention is a cold-rolled steel plate, an aluminum plate or a stainless steel plate. The fixing bar of the evaporator of the low-temperature cabinet is bent from a long cold-rolled steel plate with a thickness of 0.5 mm, and the cross-section is L-shaped. A plurality of U-shaped grooves with different intervals are arranged on one side to fix the evaporator inside, so as to ensure that the interval between the evaporator tubes is fixed. The bottom of the U-shaped groove is in contact with the other side, so that the evaporator is close to the inner tank. In order to facilitate the smooth installation of the evaporator, there are chamfers on both sides of the U-shaped groove. The chamfers can be selected from three parameters: 1mm×45°, 5mm×45°, 10mm×45°. The low-temperature cabinet evaporator fixing strip can be widely used in various refrigeration equipment, and the heat e...

Abstract

This invention discloses a fixing strip of a low temperature cabin evaporator including a first plane and a second plane connected to each other and the first plane has a U-shaped groove, the bottom of which is connected with the second plane, the cross section of the two planes is in L, chamfers are set at the top of both sides of the U-groove. This invention also discloses a low temperature cabin including a hearth set with an evaporator fixing strip at its outer wall having a first plane and a second plane, and a groove is set on one plane, an evaporator tube is inserted into the groove to set at the outer wall of the hearth by the strip. This invention also discloses a method for installing the evaporator of low temperature cabins.

Description

technical field [0001] The invention relates to a fixing technology in the field of ultra-low temperature refrigeration, in particular to a fixing technology of an evaporator tube and an inner tank. Background technique [0002] -86°C ultra-low temperature refrigerators are widely used in the fields of medicine, biological products, and electronic materials, and are used to preserve red blood cells, white blood cells, skin, bone marrow, bacteria, and low-temperature experiments on electronic devices and special materials. The inner tank of the ultra-low temperature refrigerator is generally made of steel plate, and the evaporator is wound on the inner tank. [0003] Usually, when assembling the evaporator, the bent evaporator is pre-set on the outer surface of the inner tank, and then the evaporator tube is tightly attached to the outer surface of the inner tank with aluminum foil tape, or the evaporator tube and the inner tank The thermal conductive glue is poured in betwe...
