Description

Technical Field

[0001] The utility model relates to the technical field of finned evaporators, and particularly relates to a finned evaporator convenient for maintenance. Background Art

[0002] Evaporation is a physical process in which a liquid is transformed into a gas. Generally speaking, an evaporator is an object that transforms a liquid substance into a gas. A low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat to achieve a refrigeration effect.

[0003] In the existing finned evaporators, it is very easy for dust to accumulate between the fins. Since the distance between the fins is small, it is difficult to clean the dust. It is difficult to achieve equidistant adjustment between the fins of the existing finned evaporators. Manual sliding easily causes the fins to deform or the distances to vary, and they are no longer equidistant.

[0004] The existing patent (Publication No.: CN215638142U) discloses a finned evaporator, which includes a first side plate with insertion holes, a second side plate opposite to the first side plate with insertion holes; a coil pipe arranged between the first side plate and the second side plate and relatively fixedly inserted through the first side plate and the second side plate; a first fin with insertion holes, which can be movably sleeved on the coil pipe and has threaded holes; a second fin relatively fixedly sleeved on the coil pipe; a screw rod, one end of which is connected to the first side plate and the other end is connected to the second side plate, the screw rod is matched with the threaded holes of the first fin, the screw rod passes through the central hole of the second fin, and air holes are arranged in a matrix on the screw rod; a motor is arranged at one end of the screw rod; a handle is arranged at the other end of the screw rod, and a joint is arranged on the screw rod, close to the handle end, which has the advantage of being able to adjust the distance between the fins to facilitate cleaning the dust between the fins.

It is rather troublesome to clean the dust attached to the fins, thus bringing inconvenience to users.

[0006] Therefore, a finned evaporator convenient for maintenance is proposed. Content of the Utility Model

Then, the lower fin 4 can be connected and installed to the fixed frame 1 and the heat transfer tube 2 by clamping the second clamping strip 6 in the clamping groove 7. Then, the connecting pin 804 can be sequentially passed through the first fixing block 801 and the second fixing block 802, and the bottom of the limiting ring 803 is made to contact the top of the first fixing block 801. Then, the fixing nut 805 is sleeved on the bottom surface of the connecting pin 804. Then, the fixing nut 805 is rotated, and the fixing nut 805 is moved upward through the thread to be in close contact with the bottom of the second fixing block 802, so as to connect and fix the first clamping strip 5 and the second clamping strip 6, thereby completing the installation of the upper fin 3 and the lower fin 4. By performing the above reverse operation, the upper fin 3 and the lower fin 4 can be disassembled, so as to achieve the effect of being convenient for separately disassembling, maintaining or replacing the upper fin 3 and the lower fin 4, which brings convenience to the user. Then, the fixing frame 901 is connected and installed to the fixed frame 1 by inserting the limiting rod 903 into the limiting hole 10. Then, the fixing frame 901 is connected and fixed to the fixed frame 1 by passing the fixing bolt 904 through the threaded hole 11 and into the fixing hole 12.
