Description

Technical Field

[0001] The utility model belongs to the technical field of evaporators, and more specifically, relates to an evaporator with a rotating tube bundle. 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. There are a large number of evaporators in industry, and the evaporator applied to a refrigeration system is one of them. The evaporator is a very important component among the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat to achieve the refrigeration effect. The evaporator mainly consists of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for the liquid to evaporate, prompting the liquid to boil and vaporize; the evaporation chamber completely separates the gas-liquid two-phase.

[0003] When the existing evaporator conducts heat exchange, its exhaust pipe is generally a straight pipe, with relatively low heat exchange efficiency. Moreover, after long-term use, dust will adhere to the outer wall of the pipe, affecting the heat exchange effect.

[0004] To solve the above problems, an evaporator with a rotating tube bundle is proposed in this application. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model proposes an evaporator with a rotating tube bundle to overcome the above technical problems existing in the existing related art.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] An evaporator with a rotating tube bundle includes an evaporator body. Two support rods are rotatably connected to the top of the evaporator body. The tops of the two support rods are rotatably connected to the same top plate. A positioning plate is fixedly installed on the top of the top plate. A motor is fixedly installed on one side of the positioning plate. A rotating rod is fixedly installed on the output shaft of the motor. A cleaning mechanism is provided on the rotating rod. A spiral tube is installed on the top of the evaporator body. The top end of the spiral tube is connected to the top plate. A wind guiding mechanism is provided on the top of the evaporator body, and the wind guiding mechanism cooperates with the spiral tube.

[0008] Preferably, the cleaning mechanism includes two cleaning brushes. An outer tooth ring is rotatably connected to the bottom of the top plate. A mounting plate is fixedly installed on the rotating rod. The two cleaning brushes are respectively fixedly connected to the outer tooth ring and the mounting plate, and the two cleaning brushes cooperate with the spiral tube.

[0009] The rotating rotating rod and the outer tooth ring can drive the two cleaning brushes to rotate, so as to clean the spiral tube.

[0010] Preferably, a driving gear is fixedly installed on one of the two support rods, and the driving gear meshes with the external gear ring.

[0011] The rotating support rod drives the external gear ring to rotate through the meshing of the driving gear and the external gear ring.

[0012] Preferably, a first pulley is fixedly sleeved on the rotating rod, a second pulley is fixedly sleeved on one of the two support rods, and the same belt is drivingly connected between the first pulley and the second pulley.

[0013] The rotating rod drives the corresponding support rod to rotate through the driving connection of the first pulley, the second pulley and the belt.

[0014] Preferably, the air guiding mechanism includes two arc-shaped side plates. The top of the evaporator body is rotatably connected with a bottom plate. The two arc-shaped side plates are fixedly installed on the top of the bottom plate. Guide plates are fixedly installed on both sides of the arc-shaped side plates, and the corresponding two guide plates cooperate with each other.

[0015] The arrangement of the two guide plates can facilitate the concentration of the flowing air, so that a large amount of air can pass between the two arc-shaped side plates.

[0016] Preferably, a plug column is fixedly installed on the top of the bottom plate, and the plug column cooperates with the two arc-shaped side plates.

[0017] The arrangement of the plug column, in cooperation with the two arc-shaped side plates, forms an arc-shaped channel between the plug column and the arc-shaped side plates, so that air can flow around the spiral tube, and thus the air can fully contact with the spiral tube.

[0018] In summary, the technical effects and advantages of the present utility model are as follows:

[0019] Through the driving connection of the first pulley, the second pulley and the belt, and the meshing of the driving gear and the external gear ring, the rotating rod can drive the external gear ring to rotate, and then the spiral tube can be cleaned by the two cleaning brushes.

[0020] Through the arrangement of the plug column, in cooperation with the two arc-shaped side plates, an arc-shaped channel is formed between the plug column and the arc-shaped side plates, so that air can flow around the spiral tube, and thus the air can fully contact with the spiral tube.
