[0021] See also Figure 1-4 As shown, the utility model provides a technical solution:
[0022] Embodiment 1: A refrigeration copper tube distributor, comprising a liquid inlet copper tube 1, the upper end of which is fixedly connected to a distributor body 2, the upper part of the distributor body 2 is provided with a liquid inlet branch pipe 21 in a circular array, a seat body 3 is sleeved and fixed on the liquid inlet copper tube 1, a movable seat 7 is movably provided inside the seat body 3, the outer wall of the movable seat 7 slides along the inner side wall of the seat body 3, the interior of the seat body 3 is connected to the interior of the distributor body 2, one side of the movable seat 7 is connected to an electric push fixedly installed on the outer wall of the seat body 3 The telescopic end of the rod 4 is fixedly connected, and the electric push rod 4 is controlled by an external controller. The control structure and control method do not belong to the necessary technical features of the utility model, and will not be described in detail here. A through hole 71 is opened on the movable seat 7 parallel to the liquid inlet copper tube 1. Three through holes 71 are opened on the movable seat 7 in parallel. The inner diameters of the three through holes 71 decrease from left to right. The inner diameter of the through hole 71 on the far left is the same as the inner diameter of the liquid inlet copper tube 1. Through the three through holes 71, the liquid inlet can be The gas-liquid refrigerant flow rate of the copper tube 1 entering the distributor body 2 can be realized in three states of fast, medium and slow according to needs, and is more flexible in use. The lower end of the liquid inlet copper tube 1 is fixedly connected to the inflow branch pipe 6 through the connecting bucket 5. The diameter of the inflow branch pipe 6 is smaller than the diameter of the liquid inlet copper tube 1, so that the refrigerant flow rate entering the liquid inlet copper tube 1 through the connecting bucket 5 can be slowed down. When in use, the gas-liquid refrigerant can be introduced into the liquid inlet copper tube 1 through the inflow branch pipe 6, and the refrigerant entering the liquid inlet copper tube 1 can pass through the through hole 71 and then be introduced into the distributor body 2 through the liquid inlet copper tube 1, and finally be divided into multiple branches through the liquid inlet branch pipe 21 to enter the heat exchanger. During use, when the refrigerant flow entering the distributor body 2 needs to be adjusted, the electric push rod 4 can be driven to drive the movable seat 7 to move along the inner wall of the seat body 3, so that a suitable through hole 71 is moved to a position coaxial with the liquid inlet copper tube 1, and the flow rate of the refrigerant entering the distributor body 2 can be adjusted.
[0023] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a bracket 22 is fixedly connected inside the distributor body 2, a rotating rod 23 is rotatably connected to the bracket 22 through a bearing, a mixing impeller 24 is fixedly mounted on the upper end of the rotating rod 23, and the setting of the mixing impeller 24 can achieve further mixing of the gas and liquid refrigerants entering the distributor body 2, so that the refrigerant entering the liquid inlet branch pipe 21 can be more uniform, a bracket 72 is fixedly connected inside the through hole 71, a rotating shaft 73 is rotatably connected to the bracket 72 through a bearing, and guide impellers 74 are symmetrically sleeved and fixed at the upper and lower ends of the rotating shaft 73, and the setting of the guide impeller 74 can achieve the mixing of the refrigerants passing through The refrigerant in the through hole 71 is guided, and at the same time, better mixing of the gas-liquid refrigerant can be achieved when the gas-liquid refrigerant flows through the through hole 71. The support frame 72, the rotating shaft 73 and the guide impeller 74 in the three through holes 71 are reduced from left to right to match the corresponding through holes 71. When the gas-liquid refrigerant flows through the through hole 71, the guide impeller 74 can be driven to rotate, so that the refrigerant can spiral through the through hole 71 and accelerate the gentle mixing of the gas-liquid refrigerant. After the refrigerant enters the inside of the distributor body 2, it can drive the mixing impeller 24 to rotate, so that the gas-liquid refrigerant is further mixed, so that the refrigerant entering the liquid inlet branch pipe 21 can be more uniform.
[0024] Working principle: When in use, the gas-liquid refrigerant can be introduced into the liquid inlet copper tube 1 through the inflow branch pipe 6. The refrigerant entering the liquid inlet copper tube 1 can pass through the through hole 71 and then be introduced into the distributor body 2 through the liquid inlet copper tube 1, and finally enter the heat exchanger through the liquid inlet branch pipe 21 into multiple branches. During use, when it is necessary to adjust the flow of the refrigerant entering the distributor body 2, the electric push rod 4 can be driven to drive the movable seat 7 to move along the inner wall of the seat body 3, so that a suitable through hole 71 is moved to a position coaxial with the liquid inlet copper tube 1, so that the flow of the refrigerant entering the distributor body 2 can be adjusted. When the gas-liquid refrigerant flows through the through hole 71, it can drive the guide impeller 74 to rotate, so that the refrigerant can spiral through the through hole 71 and accelerate the gentle mixing of the gas-liquid refrigerant. After the refrigerant enters the distributor body 2, it can drive the mixing impeller 24 to rotate, so that the gas-liquid refrigerant is further mixed, so that the refrigerant entering the liquid inlet branch pipe 21 can be more uniform.
