Description

Technical Field

[0001] The present application relates to the technical field of water chillers, and in particular to a high-precision air-cooled water chiller device. Background Art

[0002] A water chiller is a refrigeration device that uses water to transfer and cool heat. It is commonly used in industrial, commercial and laboratory environments to control the heat generated in equipment or processes to maintain the normal operating temperature of the equipment. The water chiller absorbs the heat generated by the equipment or process through water, then discharges the hot water and transfers it to the cooling system, eventually releasing the heat into the environment. This heat transfer process enables the equipment or process to remain within a stable temperature range.

[0003] In order to increase the heat exchange efficiency, multiple coils are often installed in the water tank of the water cooler, but the water flow rate entering each coil will be different, which will cause the temperature in each coil to be uneven. In order to maintain the uniformity of the temperature in the water tank, it is necessary to increase the operating time of the cooling equipment, which has the defect of increasing energy consumption. Utility Model Content

[0004] In order to reduce energy consumption, the present application provides a high-precision air-cooled chiller device.

[0005] The present application provides a high-precision air-cooled chiller device that adopts the following technical solutions:

[0006] A high-precision air-cooled chiller device, comprising:

[0007] A machine body, a water tank is installed in the machine body, a first water inlet, a first water outlet, a second water inlet and a second water outlet are provided on the water tank, a diverter box and a junction box are provided in the water tank, a first water inlet pipe is connected between the diverter box and the first water inlet, a first water outlet pipe is connected between the junction box and the first water outlet, a coil is connected between the diverter box and the junction box, a plurality of coils are provided, and the plurality of coils are sequentially arranged along the length direction of the diverter box;

[0008] The diverter assembly is arranged in the diverter box. The diverter assembly includes a diverter roller and a diverter blade. A diverter motor is installed on the diverter box. The output shaft end of the diverter motor is fixedly connected to the diverter roller. The diverter blade is spiral-shaped. The diverter blade is sleeved on the diverter roller and the two are fixedly connected.

[0009] By adopting the above technical scheme, the first water inlet pipe passes water into one end of the diverter box. The pressure at the end of the diverter box connected to the first water inlet pipe is high. The diverter motor is started to rotate the diverter blades through the diverter roller, thereby the diverter blades drive the water entering the diverter box forward, thereby making the water pressure in the diverter box uniform, and then making the water flow entering each coil equal, thereby improving the temperature uniformity in each coil, reducing the operating time of the equipment, and reducing energy consumption.

[0010] Optionally, a partition is fixedly provided in the diversion box, which divides the diversion box into a first area and a second area. The first water inlet pipe is connected to the first area, and the end of the coil extends into the second area and is fixed to the partition. A through hole is opened on the partition for connecting the first area with the inside of the coil.

[0011] By adopting the above technical solution, the first area is connected with the end of the coil through the through hole, so that the water in the first area directly enters each coil during the forward process, thereby making the water flow entering the coil uniform.

[0012] Optionally, a valve and a flow sensor are installed at the end of the coil extending into the second area.

[0013] With the above technical solution, the flow sensor detects the water flow entering the coil. When the water flow in the coil increases, the flow sensor reduces the opening of the valve to reduce the water flow; when the water flow in the coil decreases, the flow sensor reduces the opening of the valve to increase the water flow. With the above structure, the water flow of each coil is controlled by the flow sensor and the opening of the valve, further improving the uniformity of the water entering each coil.

[0014] Optionally, a filter tank is installed at the second water outlet.

[0015] By adopting the above technical solution, the filter tank filters the water entering the second water outlet, which can prevent solid particles or other impurities from entering the refrigeration system, helping to maintain the operating efficiency of the system and protect related equipment.

[0016] Optionally, the water tank is connected to a return pipe at the second water outlet, and a mounting sleeve is rotatably connected to one end of the filter tank close to the return pipe. The mounting sleeve is inserted into the return pipe with an interference fit between the two. A driving assembly for rotating the filter tank is provided on the water tank, and a brush is provided on one side of the filter tank.

[0017] By adopting the above technical solution, the filter tank is rotated by the driving assembly, and the filter holes of the filter tank are cleaned by the brush during the rotation of the filter tank, thereby reducing the possibility of clogging of the filter tank.

[0018] Optionally, the driving assembly includes a synchronous roller, a main synchronous wheel, a slave synchronous wheel and a synchronous belt. The synchronous roller is rotatably connected in the water tank, the main synchronous wheel is fixedly connected to the synchronous roller, the slave synchronous wheel is fixedly connected to the filter tank, the synchronous belt bypasses the main synchronous wheel and the slave synchronous wheel, and a driving motor is installed on the outer wall of the water tank, and the output shaft of the driving motor is fixed to the synchronous roller.

[0019] By adopting the above technical solution, the driving motor is started to rotate the synchronous roller, and the synchronous roller rotates the filter tank through the main synchronous wheel, the slave synchronous wheel and the synchronous belt. The driving motor is set on the outer wall of the water tank, which reduces the waterproofing work of the driving motor and reduces the cost.

[0020] Optionally, a mounting seat is fixedly provided on the inner wall of the water tank, a mounting groove is provided on the side of the mounting seat facing the brush, a mounting block which is plugged into and adapted to the mounting groove is fixedly provided on the side of the brush facing the mounting seat, and a limiting component is provided on the mounting seat to fix the mounting block in the mounting groove.

[0021] By adopting the above technical solution, the brush and the mounting block are detachably connected, and when the brush needs to be replaced, the brush can be disassembled, thereby facilitating the replacement of the brush.

[0022] Optionally, the limit assembly includes a limit rod and a reset plate, the limit rod is slidably connected in the mounting seat, a limit hole for the limit rod to pass through is opened on the mounting block, one end of the limit rod away from the mounting block extends out of the mounting seat, the reset plate is fixed to the end of the limit rod extending out of the mounting seat, and a reset spring is fixedly connected between the reset plate and the mounting seat.

[0023] By adopting the above technical solution, when the brush needs to be replaced, the limit rod is pulled out of the through hole, thereby the mounting block can be pulled out of the mounting groove, and the brush can be removed; the new brush is moved until the mounting block is inserted into the mounting groove, and the limit rod is loosened. At this time, the reset spring releases the elastic force through the reset plate to make the limit rod pass through the through hole, thereby fixing the brush. Through the above structure, the disassembly and assembly method of the brush is simple, and the disassembly and assembly efficiency is improved.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The diverter blades rotate to move the water in the diverter box forward, thereby making the water pressure in the diverter box uniform. At the same time, the flow sensor monitors the amount of water entering the coil. The valve opening is controlled according to the flow sensor, so that the water flow entering each coil is equivalent, thereby improving the temperature uniformity in each coil, reducing the operating time of the equipment and reducing energy consumption.

[0026] 2. The filter tank prevents solid particles or other impurities from entering the refrigeration system, which helps maintain the system's operating efficiency and protect related equipment; at the same time, during the rotation of the filter tank, the brush cleans the filter holes of the filter tank to reduce the possibility of clogging of the filter tank.
