Freezer compartment evaporator width = freezer compartment depth-1cm-2cm; freezer compartment length = freezer compartment width + 2× freezer compartment height. The refrigerating evaporator should be shaped into II at last to maximize the contact area with the freezer compartment.
① Straighten the copper tube at the part to be bent for about 1 meter for easy production and beautiful appearance.
②Put the copper pipe in the corresponding groove of the pipe bender, and reserve the length of the copper pipe: generally 50cm～80cm.
③ Fasten the buckle to the copper tube, slowly rotate the handle, and bend the first U-shaped tube.
④Measure the width of the evaporator. The distance between the apex of the first U-shaped tube and the top of the tube bender should be measured, plus the radius of the copper tube elbow (0.5cm). That is, when the evaporator plate is made, the measured value should be less than 0.5cm of the actual size of the evaporator. For example, for a display case, the freezer depth minus 1cm-2cm is equal to 37cm, and the actual evaporator plate size should be 36.5cm.
⑤ Bend the second U-shaped tube, and check that the evaporator width is appropriate, continue bending until the total length of the U-shaped tube = the height of the freezer compartment X2 + the width of the freezer compartment.
⑥After bending the refrigerated evaporator, keep 10cm-20cm copper as the short nozzle. The measurement method is calculated from the top of the outer U-shaped tube;
⑦ to determine the height of the freezing evaporator (the height of the freezer compartment).
⑧Bend the U-shaped pipe 90. And in the same way, the display cases evaporator is bent into II shape. According to the direction of the evaporator, bend the two nozzles 90.
5. The homemade refrigerated evaporator is a bent refrigerated evaporator. The bending method is basically the same as that of the refrigerated evaporator, except that the retention length of the two nozzles is different. The upper nozzle and the evaporator have the same width, and the lower mortar is 10cm~20cm.
display cases Evaporator plate manufacturing method The evaporator is mostly made into   back to   shape, and can also be made into   four-sided separated   shape. The  - -shaped refrigerant is horizontal, with low resistance and uniform cooling. The size error of the evaporator is required to be within 1cm. If the size exceeds the required 1.5cm or more, the copper tube of the evaporator cannot be placed flat and wavy: If the size is less than the required 1.5cm, a certain part of the evaporator cannot be fixed. display cases in the body. The   evaporating raccoon dog is separated from all sides by  . The refrigeration resistance is high and the refrigeration is uneven, but the evaporator size is high.
