[0043] In the embodiment of the present application, the water system can be a single system or a dual system. The following takes the dual system as an example to further describe the embodiment of the present application.
[0044] Please refer to Figure 3, in one embodiment, the water pump assembly 130 includes a first water pump 131 and a second water pump 132, the heat exchanger assembly 140 includes a first heat exchanger 141 and a second heat exchanger 142, and the thickness direction of the first heat exchanger 141 and the second heat exchanger 142 is the Y-axis direction; the water system includes a first system and a second system.

According to the cooling demand of the client, the operator can selectively start or connect the first system and the second system in series / parallel.
[0045] Please refer to Figure 1 , in the above embodiment, the water inlet 1111(1121) includes a first water inlet 1111 and a second water inlet 1121, and the water outlet 1112(1122) includes a first water outlet 1112 and a second water outlet 1122; the first water inlet 1111 is connected to the inlet end of the first water pump 131 through a pipe, and the first water outlet 1112 is connected to the outlet end of the second heat exchanger 142 through a pipe; the second water inlet 1121 is connected to the inlet end of the second water pump 132, and the second water outlet 1122 is connected to the outlet end of the second heat exchanger 142.
[0046] The first heat exchanger 141 has an adjacent water-cooling channel and a condensation channel.

[0047] The refrigeration system further includes an electronic expansion valve. The condensation channel of the first heat exchanger 141, the compressor 122, the condenser 123 and the electronic expansion valve are sequentially connected to form a refrigeration circuit. The refrigerant in the refrigeration system circulates in the refrigeration circuit.

[0048] The second heat exchanger 142 has a first water-cooling channel and a second water-cooling channel. The inlet and outlet of the first water-cooling channel are respectively communicated with the outlet of the water-cooling channel of the first heat exchanger 141 and the first water outlet 1112, and the inlet and outlet of the second water-cooling channel are respectively communicated with the outlet of the second water pump 132 and the second water outlet 1122.

Such an arrangement is beneficial to reducing the occurrence of corners in the pipelines connecting the components in the first system and the second system, thereby reducing the flow resistance of the coolant in the first system and the second system; at the same time, such an arrangement can also reduce the length of the pipelines connecting the components in the first system and the second system, thereby reducing the production cost of the chiller 100.
[0050] Please refer to Figure 3 , in the above embodiments, more specifically, the inlet end of the first water pump 131 is arranged at the right end of the first water pump 131, and the inlet end of the second water pump 132 is arranged at the left end of the second water pump 132; the first water inlet 1111 is arranged at the right end of the front side of the housing 110, and the second water inlet 1121 is arranged at the left end of the front side of the housing 110.

In a specific embodiment, the first heat exchanger 141 is a water-fluorine plate heat exchanger, and the second heat exchanger 142 is a water-water plate heat exchanger. The following takes this as an example to further illustrate the embodiments of the present application.
[0052] Please refer to Figure 2 and Figure 3 , on the basis of the above embodiments, in one embodiment, the first system further includes a heater 150, and the heater 150 is arranged below the expansion tank 124.
[0053] Specifically, the expansion tank 124 is placed horizontally in the first chamber, the placement height of the expansion tank 124 is higher than that of the water pump assembly 130, the heater 150 is located behind the water pump assembly 130, the inlet of the heater 150 is arranged at the right end of the heater 150, and the outlet of the heater 150 is arranged at the left end of the heater 150.
[0054] In the above embodiment, the inlet and outlet of the heater 150 are respectively communicated with the outlet at the front end of the water-cooling channel of the water-fluoride plate heat exchanger 141 and the inlet at the front end of the first channel of the water-water plate heat exchanger 142 through pipelines. During the operation process, the heater 150 can be selectively started and stopped according to the refrigeration or heating requirements. For example, when heat dissipation is required for the client, the heater 150 can be turned off, while in a cold environment, when it is necessary to appropriately increase the temperature of the client, the heater 150 can be turned on.
[0055] In the above embodiment, the main flow path of the coolant in the first system is as follows: the first water inlet 1111 → the first water pump 131 → the water-cooling channel of the water-fluoride plate heat exchanger 141 → the heater 150 → the first water-cooling channel of the water-water plate heat exchanger 142 → the first water outlet 1112.
[0056] Please refer to Figure 1 and Figure 3 , in an embodiment, the second system further includes an air-cooled condenser 170, and the air-cooled condenser 170 is arranged at one end of the compressor 122 away from the expansion tank 124. Specifically, the air-cooled condenser 170 is arranged in front of the condenser 123, and the air-cooled condenser 170 and the condenser 123 are arranged side by side along the length direction of the housing 110. The inlet and outlet of the air-cooled condenser 170 are respectively connected to the outlet of the second water pump 132 and the inlet of the second water-cooling channel of the water-water plate heat exchanger 142.
[0057] Please refer to Figure 2 and Figure 3 , further, the second system further includes a regulating valve 160 for regulating the flow rate of the coolant in the second system. Specifically, the regulating valve 160 is a two-way valve, and the two-way valve 160 is arranged on the side of the air-cooled condenser 170 close to the water-water plate heat exchanger 142, that is, the two-way valve 160 is arranged in front of the air-cooled condenser 170. The second water pump 132, the air-cooled condenser 170, the regulating valve 160 and the water-water plate heat exchanger 142 are sequentially connected through pipelines. The main flow path of the coolant in the second system is as follows: the second water inlet 1121 → the second water pump 132 → the air-cooled condenser 170 → the two-way valve → the second water-cooling channel of the water-water plate heat exchanger 142 → the second water outlet 1122.
[0058] Please refer to Figure 1 and Figure 2, in the embodiment of the present application, the chiller 100 further includes an electric control box 180, and the electric control box 180 is disposed on a side of the water-to-fluoride plate heat exchanger 141 or the water-to-water plate heat exchanger 142 away from the expansion tank 124. Preferably, the electric control box 180 is disposed on the right side of the water-to-fluoride plate heat exchanger 141. Such an arrangement makes the layout of the connection heads of the electric control box 180 more convenient.
[0059] In the embodiment of the present application, by reasonably arranging the water system, the refrigeration system and the electric control box 180 in the limited space within the housing 110, not only the overall space occupancy of the chiller 100 is relatively small, but also the pipeline system of each component in the water system of the chiller 100 is simpler and the number of pipeline corners is less, which can reduce the flow resistance of the coolant in the water system and can reduce the production cost of the chiller 100.
[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
