Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration pipelines, in particular to a refrigeration pipeline for an evaporator of a refrigeration unit. Background Art

[0002] The evaporator in the refrigeration unit is a key component. Its main function is to absorb heat through the evaporation process of the refrigerant to achieve the purpose of refrigeration. The refrigeration pipe is the channel connecting the evaporator with other refrigeration system components. Through these pipes, the refrigerant can circulate in the system to complete the process of heat absorption, transportation and heat release.

[0003] Common refrigeration pipes are cylindrical pipe structures. In order to increase the contact area with air or other cooling media, fins are generally added to the bottom of the refrigeration pipe. However, due to the hollow structure inside, the contact area between the refrigerant or gas and the inner wall of the pipe is limited when flowing through the refrigeration pipe, resulting in poor heat exchange quality and failure to meet the working requirements of the refrigeration pipe. Therefore, a refrigeration unit evaporator refrigeration pipe is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a refrigeration pipe for an evaporator of a refrigeration unit to solve the technical problem that due to its hollow internal structure, the contact area between the refrigerant or gas and the inner wall of the pipe is limited when flowing through the refrigeration pipe, resulting in poor heat exchange quality.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a refrigeration pipeline of an evaporator of a refrigeration unit, comprising:

[0006] A main pipe, wherein fins are connected to the middle position of the bottom and the left and right sides of the main pipe, and flanges are installed at both left and right ends of the main pipe;

[0007] The protruding teeth are installed on the upper and lower sides and the left and right sides of the main pipe. The left and right sides of the inner cavity of the main pipe are clamped with step rings, and the inner circumference of the step ring is equipped with flanges.

[0008] Preferably, the interior of the main pipe is filled with aluminum silicate thermal insulation cotton, and the number of the flanges is 3-6 groups, thereby improving the thermal insulation performance of the main pipe.

[0009] Preferably, sealing gaskets are clamped on both the inner and outer sides of the flange, and mounting pins are circumferentially installed on the inner side of the flange. The added sealing gaskets improve the sealing performance after the main pipe is connected.

[0010] Preferably, limit rods are inserted into the inner and outer sides of the mounting pin, and the outer ends of the limit rods are connected to the corresponding positions on the inner side of the sealing gasket, and ratchet plates are installed on the left and right sides of the inner cavity of the mounting pin.

[0011] Preferably, the inner ends of the limit rods are sleeved with C-shaped plates, the inner sides of the C-shaped plates are connected to springs, the inner ends of the springs are connected to the corresponding positions of the inner cavities of the mounting pins, the number of the springs is 2-4 groups, and the movement of the C-shaped plates can be driven by the springs.

[0012] Preferably, the front and rear sides of the C-shaped plate are equipped with latches through bearings, and the outer parts of the latches are inserted between the tooth grooves of the ratchet plate. The added latches and ratchet plate prevent the limit rod from moving inward, so that when the sealing gasket is worn, the C-shaped plate and the limit rod can be pushed by the spring, so that the sealing gasket can always be pressed tightly.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The refrigeration pipe of the evaporator of the refrigeration unit increases the contact area when the gas or liquid flows through by adding convex teeth on the upper and lower sides and the left and right sides inside the main pipe, so that the gas exchange area of ​​the pipe becomes larger, the refrigeration area is increased, and the quality of the refrigeration pipe when in use is improved. At the same time, the added step ring and its internal flange can improve the distribution of gas and liquid, so that the gas and liquid can contact and pass into the main pipe more evenly, thereby improving the mass transfer efficiency.
