[0002] The evaporative condenser is the main heat exchange equipment in the refrigeration system. Its working principle is: the superheated high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condensation pipe in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the pipe. That is, the gaseous refrigerant enters the pipe from the top and is gradually condensed into liquid refrigerant from top to bottom.

[0003] After searching, the Chinese patent publication number CN218442871U discloses "a water-saving evaporative condenser, comprising a condenser body, an air outlet pipe is provided at the upper end of the condenser body, an air inlet pipe is provided at the side wall of the condenser body, a condensation coil is provided in the condenser body, a mounting plate is fixedly connected to the inner wall of the air outlet pipe, a cavity is provided in the mounting plate, a driving mechanism is connected to the side wall of the air outlet pipe, a water-saving plate is fixedly connected to the lower end of the mounting plate, a plurality of air holes are provided in the water-saving plate, an exhaust mechanism is provided in the cavity, the driving mechanism and the exhaust mechanism are connected by a transmission mechanism, and a water collecting tank is fixedly connected to the inner wall of the condenser body".

However, since there is a gap between the water spray outlets on the spray pipe, the amount of water sprayed at the gap between the two water spray outlets of the condensing coil will be less than that in other areas, which causes uneven distribution of the spray water, thereby affecting the overall heat exchange effect. In view of this, the utility model proposes a water-saving evaporative condenser. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 5 As shown, this embodiment proposes a water-saving evaporative condenser, including a shell 1, one side of the shell 1 is fixedly connected with an air inlet pipe 3, the bottom end of the inner side of the shell 1 is fixedly connected with a mounting seat 4, the top of the mounting seat 4 is fixedly connected with a condensing coil 5, the top of the shell 1 is fixedly connected with an air suction cylinder 6, the inner side of the air suction cylinder 6 is rotatably connected with a hollow shaft 7 that penetrates the air suction cylinder 6, the middle part of the hollow shaft 7 is fixedly connected with an axial flow impeller 8, the bottom end of the hollow shaft 7 is provided with a spraying member 9 for spraying the condensing coil 5 by rotation, the top of the air suction cylinder 6 is provided with a driving member 10 for driving the hollow shaft 7 to rotate, the bottom end of the hollow shaft 7 is provided with a top pressure member 13 for driving the hollow shaft 7 to slide reciprocatingly up and down by cooperating with the rotation of the hollow shaft 7, the bottom of the shell 1 is fixedly connected with a water collecting box 2 for collecting spray water, and one end of the water collecting box 2 is fixedly connected with a drain pipe 21.

[0024] The driving member 10 drives the hollow shaft 7 to rotate, which causes the axial flow impeller 8 to rotate, thereby reducing the internal pressure of the suction cylinder 6, so that the gas inside the shell 1 is sucked out and the internal pressure of the shell 1 is reduced, which allows the air inlet pipe 3 to introduce external air to exchange heat with the condensing coil 5, and the hollow shaft 7 drives the spray member 9 to rotate and spray the condensing coil 5. At the same time, the top pressure member 13 can drive the hollow shaft 7 to slide back and forth up and down, which also causes the spray member 9 to reciprocate up and down, which can greatly increase the spray range of the spray member 9, so that the spray water on the condensing coil 5 is evenly distributed, thereby greatly improving the heat exchange effect.

[0025] Furthermore, the spraying member 9 includes a U-shaped tube 91, the top of which is fixedly connected to the hollow shaft 7, and a plurality of water spray heads 92 communicating with the inside of the U-shaped tube 91 are fixedly connected to the inner walls of both ends of the U-shaped tube 91, the width of the U-shaped tube 91 is greater than the diameter of the condensing coil 5, and the length of the U-shaped tube 91 is greater than the length of the condensing coil 5, and a water pump 11 is fixedly installed on the housing 1, the inlet end of the water pump 11 is connected to the water source through a conduit, and the outlet end of the water pump 11 is fixedly connected to a water hose 12, which passes through the hollow shaft 7 and is connected to the inside of the U-shaped tube 91. Water is introduced into the water hose 12 through the water pump 11, and then introduced into the U-shaped tube 91 through the water hose 12, and then sprayed out through each water spray head 92, thereby realizing the spraying work on the condensing coil 5.

[0026] Furthermore, the driving member 10 includes a motor 101, which is fixedly mounted on the top of the suction cylinder 6, and the output shaft of the motor 101 is fixedly connected with a spline 102, and the top of the hollow shaft 7 is fixedly connected with a ring gear 103, which meshes with the spline 102 and can translate along the axial direction of the spline 102, and a spring 104 is sleeved on the hollow shaft 7, and the top of the spring 104 is in contact with the ring gear 103, and the bottom of the spring 104 is in contact with the top wall of the suction cylinder 6. By starting the motor 101, the spline 102 can be rotated, which causes the ring gear 103 to rotate, so that the hollow shaft 7 drives the U-shaped tube 91 to rotate synchronously, and the U-shaped tube 91 can be rotated to spray.

[0027] Furthermore, the pressing member 13 includes a rotating plate 131, one end of which is fixedly connected to the hollow shaft 7, the other end of which is fixedly connected to a protrusion 132, and the outer edge of the top wall on the inner side of the shell 1 is fixedly connected to a top block 133, and the protrusion 132 intermittently conflicts with the top block 133 by following the rotation of the rotating plate 131. By starting the motor 101, the spline 102 can be rotated, which makes the ring gear 103 rotate, thereby making the hollow shaft 7 rotate, which makes the rotating plate 131 rotate, and the protrusion 132 rotates synchronously with the rotating plate 131. When the protrusion 132 conflicts with the top block 133, the protrusion 132 is moved downward by the action of the top block 133, which makes the hollow shaft 7 drive the ring gear 103 to move downward. At this time, the spring 104 is compressed to accumulate potential energy. When the protrusion 132 is disengaged from the top block 133, the spring 104 releases the potential energy, which makes the ring gear 103 drive the hollow shaft 7 to slide upward. In this cycle, the hollow shaft 7 can realize up and down reciprocating movement, which can greatly increase the spraying range of the spray member 9.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
