specifically, referring to fig. 4 and 5, a communicating groove penetrating through a sidewall of the partition board 4 is formed at a top of the partition board 4, a conical tube 42 is arranged at a right end of the communicating groove, a diameter ratio of an inlet and an outlet is changed to enable the refrigerant flowing into the U-shaped switching tube 43 to be sprayed out at a faster speed, the U-shaped switching tube 43 is arranged at a right end of the conical tube 42, the U-shaped switching tube 43 is just similar to a U-shape, the function of the U-shaped switching tube is to change the flow direction of the refrigerant, a spray head 44 is arranged at one end of the U-shaped switching tube 43 far from the conical tube 42, and the spray head 44 is integrally strip-shaped, but one side, close to each other, of the two spray heads 44 on the same partition board 4 and one side, far from each other, are respectively bent upwards and downwards, so that the refrigerant sprayed out of the spray head 44 can cover each heat exchange tube 3, and thus the heat exchange tube 3 cannot maintain a high temperature state by a small amount of continuous spraying.
Therefore, the specific implementation manner of this embodiment is as follows:
after the part of the cavity close to the liquid inlet of the shell 1 is filled with the refrigerant, the motor 111 controls the driving assembly 12 to rotate, so that the partition board 4 moves leftwards to compress the space in the part of the cavity, so that the refrigerant can flow into the next cavity through a gap between the inclined baffle 41 and the top of the inner wall of the shell 1, and other refrigerants can be quickly and uniformly sprayed onto the heat exchange tube 3 in the next cavity through the conical tube 42, the U-shaped switching tube 43 and the spray head 44, the temperature of the heat exchange tube 3 is further reduced, the part of the heat exchange tube 3 is prevented from being in a high-temperature state for a long time, and the damage of the heat exchange tube 3 is accelerated.

specifically, the length of the regular hexagonal snap ring 61 is smaller than the distance between the left end of the rotating rod 121 and the inner clamping ring 127, and the regular hexagonal rubber ring 62 has a certain toughness, so that the regular hexagonal snap ring 61 is sleeved on the outer side of the movable ring 67 again under the action of the elastic telescopic rod 69 and can move left a small distance in advance, and a certain distance is reserved to serve as a buffer space, so that the reliability of the device is improved.
Therefore, the specific implementation manner of this embodiment is as follows:
when the driving assembly 12 rotates clockwise, the spacing mechanism 6 is driven to rotate in the regular hexagonal groove 125 while the spacing plate 4 is controlled to move left and right to compress the space of a part of the cavity in the shell 1 and accelerate the flow of the refrigerant, then the regular hexagonal clamping ring 61 drives the moving ring 67 to rotate through the pawl 652 and the ratchet 65, and simultaneously the second sliding ball is moved back into the threaded groove 126 from the annular groove 128 by the rebound action of the elastic telescopic rod 69, so that the spacing mechanism 6 can move right to be separated from the rotating rod 121 positioned at the left side of the spacing mechanism 6, the connection of the two adjacent spacing mechanisms 6 is interrupted, the spacing mechanism 6 can not move in the rotation of the spacing plate 4 positioned at the left side in the shell 1 after the driving assembly 12, and then the spacing mechanism 6 continues to move a small distance, so that the clamping ring 127 enters the accommodating annular groove 63;
when the driving assembly 12 rotates anticlockwise, the regular hexagonal snap ring 61 drives the moving ring 67 to rotate through the pawl 662 and the ratchet 66, and moves leftwards by using the sliding ball 662 and the threaded groove 126, at this time, the regular hexagonal snap ring 61 stays at the current position because the clamping ring 127 is located in the receiving ring groove 63, and when the moving ring 67 enters the regular hexagonal groove 125 in the rotating rod 121 located at the left side of the limiting mechanism 6, and the elastic force of the elastic telescopic rod 69 is greater than the interaction force between the clamping ring 127 and the regular hexagonal rubber ring 62, the regular hexagonal snap ring 61 suddenly enters the regular hexagonal groove 125 in the rotating rod 121 located at the left side of the limiting mechanism 6 through the rebound pulling force of the moving ring 67 in a time interval when the rotating rod 121 rotates once every 60 °, so as to reconnect the two adjacent rotating rods 121.
