Inside the water chilling unit, the fan drives air to flow from the air inlet to the air outlet. When the air flows through the heat exchanger, heat exchange is carried out with the heat exchanger. If the heat exchanger and the inner wall of the shell are provided with gaps, the wind resistance of the heat exchanger is larger, and a part of air flows from the gaps between the heat exchanger and the inner wall of the shell to influence the heat exchange effect of the heat exchanger, so that the refrigeration efficiency of the water chilling unit is influenced.

In order to improve the heat exchange effect of the heat exchanger, referring to fig. 1-4, an embodiment of the disclosure provides a water chiller, which includes a box 100, a fan fixing plate 200, a fan 300, a wind guide ring 400 and a heat exchanger 500, wherein the box 100 is provided with an air inlet 110 and an air outlet 120; the fan fixing plate 200 is arranged in the box body 100 corresponding to the air outlet 120, and the fan fixing plate 200 is provided with a mounting window; the fan 300 is fixed on the first surface of the fan fixing plate 200 corresponding to the mounting window, and the fan 300 drives air to pass through the mounting window; the first end of the air guide ring 400 is abutted to the second surface of the fan fixing plate 200 and covers the mounting window; the air guide ring 400 and the fan fixing plate 200 are enclosed to define a heat exchanger installation space; the heat exchanger 500 is disposed in the heat exchanger installation space.

In the embodiment of the disclosure, the water chiller includes a box 100, where the box 100 is configured with a containing space, and an air inlet 110 and an air outlet 120 that are communicated with the containing space are formed. The fan fixing plate 200 is disposed in the accommodating space of the case 100, and the fan 300 is fixed to the fan fixing plate 200. The fan fixing plate 200 is disposed corresponding to the air outlet 120, and the fan 300 is also disposed corresponding to the air outlet 120. In this way, when the fan 300 drives the air to flow from the air inlet 110 to the air outlet 120, the air pressure loss is small, and the air output of the water chiller can be improved.

The fan fixing plate 200 is provided with a mounting window, and the fan 300 is fixed to the first surface of the fan fixing plate 200 corresponding to the mounting window. The first surface of the fan fixing plate 200 faces the air outlet 120, and the side where the first surface is located is a first side; the second surface of the fan fixing plate 200 faces the air inlet 110, and the side where the fan fixing plate is located is the second side. When the blower fan 300 rotates, air driving the second side of the blower fan fixing plate 200 flows to the first side of the blower fan fixing plate 200 through the mounting window.

The fan fixing plate 200 has a positive pressure push-out region on a first side and a negative pressure suction region on a second side.

The wind guide ring 400 has a hollow cylindrical shape with two open ends, and two distal ends along the axial direction thereof are a first end and a second end respectively. The wind guide ring 400 is fixed to the second face of the fan fixing plate 200. The wind-guiding ring 400 covers a mounting window, i.e. the opening of the first end of the wind-guiding ring 400 is larger than or the opening of the rain-shielding mounting window, which is located in the projection of the wind-guiding ring 400 in the fan fixing plate 200.

When the blower 300 rotates, the air in the negative pressure suction area passes through the air guide ring 400 and then enters the positive pressure push-out area through the installation window.

The air guide ring 400 and the fan fixing plate 200 define a heat exchanger installation space, and the heat exchanger 500 is located in the heat exchanger installation space. The thickness direction of the heat exchanger 500 is along the axial direction of the air duct. Thus, the air flowing through the air duct of the heat exchanger 500 can exchange heat sufficiently, thereby achieving better heat exchange effect.

By using the water chilling unit provided by the embodiment of the disclosure, the fan 300 bracket and the air duct simultaneously fix the fan 300 and the heat exchanger 500, so that the space occupied by the fan 300 and the heat exchanger 500 is reduced, and the miniaturization of the water chilling unit is facilitated; the heat exchanger 500 is installed in the air duct, and air flows through the air duct, so that air can be prevented from flowing from a gap between the heat exchanger 500 and the inner wall of the box body 100, and forced air flows through the heat exchanger 500, so that the heat exchange effect of the heat exchanger 500 is improved.

Optionally, the fan 300 includes a fan barrel 310, a motor 320, and fan blades, wherein the fan barrel 310 has a first end facing the air outlet 120 and a second end abutting against the mounting window; a motor 320 fixed to the blower cylinder 310; and fan blades fixed to an output shaft of the motor 320.

The motor cylinder is a hollow cylinder with two open ends, and two distal ends along the axial direction of the motor cylinder are respectively a first end and a second end. The second end of the motor cartridge interfaces with a mounting window, i.e., the mounting window is located within the projection of the motor cartridge to the fan mounting plate 200. The output shaft of the motor 320 is disposed along the axial direction of the motor cylinder, and the blades extend along the radial direction of the output shaft of the motor 320. When the motor 320 rotates, the blades push air to flow along the axial direction of the motor cylinder. The fan 300 is in the form of an axial flow fan, and has a simple structure and large air output.

Alternatively, the outer ring of the fan fixing plate 200 abuts against the inner wall of the case 100.

When the blower 300 rotates, the first side of the blower fixing plate 200 is a positive pressure pushing-out area, and the second side is a negative pressure suction area. If there is a gap between the fan fixing plate 200 and the inner wall of the case 100, the air in the positive pressure push-out region may return to the negative pressure suction region through the gap between the fan fixing plate 200 and the inner wall of the case 100. Thus, the pressure difference at two sides of the fan fixing plate 200 is reduced, and the air output of the water cooling unit is further affected. The outer ring of the fan fixing plate 200 is abutted against the inner wall of the box body 100, no gap or small gap exists between the fan fixing plate 200 and the inner wall of the box body 100, and air in the positive pressure pushing-out area is not easy to return to the negative pressure suction area through the gap between the fan fixing plate 200 and the inner wall of the box body 100. Therefore, the pressure difference at two sides of the fan fixing plate 200 is improved, which is beneficial for the fan 300 to drive more air to flow through the heat exchanger 500, so that the heat exchange effect of the heat exchanger 500 is improved, and the refrigeration efficiency of the water-cooling unit is improved.

Optionally, the fan fixing plate 200 is provided with a plurality of mounting windows, and the water chilling unit includes a plurality of fans, where the fans are in one-to-one correspondence with the mounting windows.

The cross section of the fan is circular, and the shape of the fan fixing plate 200 is affected by the cross section of the water-cooling unit case 100. The fan fixing plate 200 is provided with a plurality of mounting windows, each of which is provided with a fan 300. Thus, the arrangement of the fans 300 is not affected by the shape of the fan fixing plate 200, and the air output of the water-cooling unit is improved by increasing the number of the fans 300. Illustratively, the fan fixing plate 200 is provided with three mounting windows, each of which is provided with a fan 300. Thus, even if the aspect ratio of the fan fixing plate 200 exceeds three to one, the water cooling unit can have a high air output.

Optionally, the wind-guiding ring 400 covers a plurality of mounting windows.

Unlike the blower 300, the shape of the heat exchanger 500 may be adapted to the shape of the blower fixing plate 200. Therefore, in the case where the fan fixing plate 200 is provided with a plurality of mounting windows, the wind guide ring 400 covers all of the mounting windows. When the blower 300 is operated, air enters the air guide ring 400 and then exchanges heat with the heat exchanger 500. The air flowing through the heat exchanger 500 is branched to the plurality of installation windows, and flows toward the air outlet 120 of the case 100 by the driving of the plurality of fans 300. With such arrangement, the air guide ring 400 has a relatively simple structure, and the heat exchanger 500 can achieve a relatively good heat exchange effect.

Optionally, the fan fixing plate 200 has a plurality of sides, the air guide ring 400 includes a plurality of baffles 410, the plurality of baffles 410 extend from the plurality of sides of the fan fixing plate 200 in a one-to-one correspondence, and the plurality of baffles 410 and the fan fixing plate 200 enclose a heat exchanger installation space.

Illustratively, the fan fixing plate 200 is rectangular with four sides. The wind guide ring 400 includes four baffles 410, and the four baffles 410 extend toward the second side of the fan fixing plate 200 to the four sides of the fan fixing plate 200, respectively. The four baffles 410 are spliced to form the air guide ring 400, that is, the air guide ring 400 is disposed along the outer circumference of the fan fixing plate 200. The size of the heat exchanger 500 is limited by the size of the heat exchanger installation space. With such an arrangement, the area of the air guide ring 400 is large, and the size of the heat exchanger 500 is large. The heat exchanger 500 is large in size and large in heat exchange area. Thus, the heat exchange effect of the heat exchanger 500 can be further improved, and the efficiency of the water chilling unit is improved.

Alternatively, the plurality of baffles 410 are integrally provided with the fan fixing plate 200, and the plurality of baffles 410 form a predetermined angle with the fan fixing plate 200 by bending.

The fan fixing plate 200 and the plurality of baffles 410 are the same plate body. The fan fixing plate 200 and the plurality of baffles 410 are cut out from the plate body, and then the plurality of baffles 410 are bent to a preset angle in the same direction of the plate body. With such an arrangement, the structural strength between the fan fixing plate 200 and the plurality of baffles 410 is higher, and the process is simple and the cost is low.

Optionally, the heat exchanger 500 includes a heat exchanger body and a fixing base 520, wherein the heat exchanger body is used for exchanging heat with air flowing through the heat exchanger 500; the fixing base 520 is connected to the heat exchanger body, and the fixing base 520 is fixed on the second surface of the fan fixing plate 200.

The heat exchanger body is internally provided with a refrigerant flow passage, and the refrigerant flows in the refrigerant flow passage to exchange heat with air flowing through the outside of the heat exchanger 500 body. The fixing base 520 is used for fixing the heat exchanger body to the fan fixing plate 200. The blower 300 is fixed to a first face of the blower fixing plate 200, and the heat exchanger 500 is located at a second face of the blower fixing plate 200. Thus, the structure between the heat exchanger 500 and the fan 300 is more compact, which is beneficial to reducing the volume of the water chilling unit.

Optionally, the heat exchanger 500 includes a first gas collecting tube 511, a second gas collecting tube 512, and a plurality of refrigerant tubes 513, wherein two ends of each refrigerant tube 513 in the plurality of refrigerant tubes 513 are respectively connected to the first gas collecting tube 511 and the second gas collecting tube 512 to form a refrigerant flow channel.

With such arrangement, the plurality of refrigerant pipes 513 are connected in parallel, so that the flow resistance of the refrigerant in the heat exchanger 500 can be reduced, thereby improving the flow rate of the refrigerant and further improving the heat exchange efficiency of the heat exchanger 500.

Optionally, the fixing base 520 includes a base and a clamping ring, the clamping ring is configured with a clamping space, the first gas collecting tube 511 or the second gas collecting tube 512 is penetrated in the clamping space, the clamping part is fixed on the fixing base 520, and the fixing base 520 is fixed on the fan fixing plate 200.

Optionally, the clamping ring is provided with a notch, and the first gas collecting tube 511 or the second gas collecting tube 512 is clamped into the clamping space through the notch.

With the adoption of the arrangement form, the disassembly and assembly between the heat exchanger body and the fixing seat 520 are convenient.

Alternatively, the fixing base 520 is connected to the fan fixing plate 200 by bolts, which penetrate from the first face of the fan fixing plate 200.

The heat exchanger 500 is sized to fit the size of the fan fixing plate 200, and is not easily operated from the second side of the fan fixing plate 200. When the heat exchanger 500 is installed, the heat exchanger 500 is pre-positioned and then bolts are inserted from the first side of the fan fixing plate 200 to fix the fixing base 520 to the second side of the fan fixing plate 200. With such arrangement, the heat exchanger 500 is easily assembled and disassembled.

Optionally, the number of the fixing bases 520 is plural, and the plurality of fixing bases 520 are connected to the first gas collecting tube 511 and/or the second gas collecting tube 512.

The number of the fixing seats 520 is four, and two fixing seats 520 are connected to the first gas collecting pipe 511 and two fixing seats 520 are connected to the second gas collecting pipe 512. By adopting the arrangement mode, the fixing effect on the heat exchanger body is relatively good.

Alternatively, the number of the heat exchangers 500 is plural, and the plurality of heat exchangers 500 are spliced and arranged in the heat exchanger installation space.

The length-width dimension of the heat exchanger installation space corresponds to the length-width dimension of the fan fixing plate 200. The heat exchangers 500 are spliced on the same plane, so that the wind resistance of the heat exchangers 500 can be reduced, and the air output of the water chilling unit is improved.

Optionally, each of the plurality of heat exchangers 500 includes a first gas collecting tube 511, a second gas collecting tube 512 and a fixing base 520, and the plurality of heat exchangers 500 are respectively fixed to the fan fixing plate 200 through the fixing bases 520 included therein.

With such an arrangement, each heat exchanger 500 of the plurality of heat exchangers 500 can be conveniently fixed to the heat exchanger installation space.

Optionally, the first gas collecting tube 511 is divided into a plurality of sections not communicated with each other, the second gas collecting tube 512 is divided into a plurality of sections not communicated with each other, and a plurality of refrigerant tubes 513 are connected between each section of the first gas collecting tube 511 and the corresponding second gas collecting tube 512, thereby forming a plurality of heat exchanging passages.

With such arrangement, the plurality of heat exchangers 500 are integrated, thereby facilitating transportation and installation of the plurality of heat exchangers 500.

Illustratively, a baffle is disposed in the first header 511 to divide the first header 511 into a first section and a second section; a baffle is provided in the second header 512 to divide the second header 512 into a first section and a second section. A plurality of refrigerant tubes 513 are provided between the first section of the first gas collecting tube 511 and the first section of the second gas collecting tube 512 to form a first heat exchanging path; a plurality of refrigerant tubes 513 are provided between the second section of the first header 511 and the second end of the second header 512 to form a second heat exchange path. The heat exchanger 500 has a first heat exchange path and a second heat exchange path formed therein, and the first heat exchange path and the second heat exchange path are connected in parallel. When the water chilling unit operates, only the first heat exchange passage can be selected to work, only the second heat exchange passage can be selected to work or the first heat exchange passage and the second heat exchange passage can work together according to refrigeration requirements. By adopting the arrangement mode, the working state of the heat exchanger 500 can be adapted to the refrigeration requirement of the water chilling unit, and the use of a user is facilitated.

Alternatively, the number of the heat exchangers 500 is plural, and the plurality of heat exchangers 500 are stacked.

Illustratively, the number of heat exchangers 500 is two, a first heat exchanger 500 and a second heat exchanger 500, respectively. When the water chiller operates, air flows through the first heat exchanger 500, the second heat exchanger 500, the installation window, and the blower 300 in this order. With such arrangement, the heat exchange area of the heat exchanger 500 can be increased, thereby improving the heat exchange efficiency of the heat exchanger 500. Although the lamination of the first heat exchanger 500 and the second heat exchanger 500 increases the wind resistance, the air does not flow through the gaps between the first heat exchanger 500 and the second heat exchanger 500 and the casing 100 of the water chiller, and the heat exchanger 500 can still obtain a good heat exchange effect.

Optionally, the chiller further includes a compressor 600, the compressor 600 is disposed between the air inlet 110 and the air outlet 120, and the fan 300 drives air to flow through the compressor 600 to reduce the temperature of the compressor 600.
