Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to a three-channel water chiller. Background Art

[0002] A water chiller is a cooling water device that can provide constant temperature, constant flow and constant pressure. A certain amount of water is injected into the water tank inside the machine in advance, and the water is cooled by the chiller's refrigeration system. The low-temperature cooling water is then pumped into the equipment to be cooled by a water pump. The chilled water in the chiller takes away the heat, then the temperature rises and flows back to the water tank to achieve the cooling effect.

DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0024] The utility model is a three-channel chiller, comprising a chassis 1, wherein the chassis 1 is provided with a plurality of coolant outflow pipes 11 and a plurality of coolant return pipes 12 on the outside; the chassis 1 is provided with a cooling system 2, a liquid storage tank 3, a temperature control mechanism 4 and a plurality of pressure pumps 5 inside, wherein the liquid storage tank 3 is used to store coolant, the cooling system 2 is used for coolant refrigeration, the temperature control mechanism 4 assists in controlling the temperature of the coolant, and the pressure pump 5 provides pressure to pump out the coolant with controlled temperature through the coolant outflow pipe 11 and flow into an external device, and the used coolant flows from the external device through the coolant inflow pipe back to the liquid storage tank 3, forming a coolant circulation. The utility model has the following advantages: 1. Three coolant inlet and outlet channels are provided, which can meet the cooling needs of multiple devices at the same time; 2. The cooling system 2 is equipped with a temperature control device, and the coolant temperature can be continuously controlled, thereby reducing the error between the actual coolant temperature and the ideal coolant temperature.

[0025] Preferably, the cooling system 2 comprises a compressor 21, a shell and tube condenser 22 and a plate heat exchanger 23 which are connected in sequence, wherein the plate heat exchanger 23 is connected to the compressor 21; the liquid storage tank 3 is connected to the plate heat exchanger 23. Figure 5 As shown. The compressor 21 provides high-temperature refrigerant gas. When the refrigerant gas reaches the shell and tube condenser 22, it is cooled and liquefied into a low-temperature refrigerant liquid, and then reaches the plate heat exchanger 23. The plate heat exchanger 23, as an energy exchange medium, transfers the coldness of the refrigerant liquid to the cooling liquid. After that, the refrigerant heats up and returns to the compressor 21 again, forming a refrigeration cycle, and the instantly cooled cooling liquid flows into the temperature control mechanism 4. The cooling system 2 of this technical solution has a simple structure and a low preparation cost. A shock-absorbing spring is arranged at the bottom of the compressor 21 to reduce the noise pollution and vibration impact caused by the vibration of the compressor 21 during operation.

[0026] Preferably, the temperature control mechanism 4 comprises a heater 41 , one end of the heater 41 is connected to the liquid storage tank 3 , and the other end of the heater 41 is connected to the pressure pump 5 .

[0027] In order to further improve the technical solution, a first temperature sensor 42 is provided between the heater 41 and the liquid storage tank 3 , and a second temperature sensor 43 is provided between the heater 41 and the pressure pump 5 .

[0028] The cooled coolant first passes through the first temperature sensor 42, which detects the coolant temperature. When the coolant temperature reaches the expected standard, the heater 41 is not turned on. When the coolant temperature is too low, the heater 41 is turned on to further regulate the coolant temperature. The regulated coolant flows into the second temperature sensor 43, which detects the coolant temperature again. The detected coolant is pumped out at high pressure through the pressure pump 5.

[0029] The utility model further installs a temperature control mechanism 4 after the cooling system 2, detects the temperature of the coolant in real time, and can control the temperature of the coolant, thereby significantly reducing the error of the coolant temperature.

[0030] Preferably, the chassis 1 is equipped with a pressure gauge 13 for monitoring the pressure of the cooling system 2 , mainly for detecting the pressure of the compressor 21 .

[0031] In the technical solution, the coolant outflow pipe 11 and the coolant return pipe 12 are both provided with a first valve 14. When the coolant outflow pipe 11 or the coolant inflow pipe is connected to an external device, the first valve 14 is opened, and when the pipe is not connected to an external device, the first valve 14 is closed.

[0032] Preferably, the multiple coolant outflow pipes 11 and the multiple coolant return pipes 12 are all connected to a high-pressure air circuit 6 for blowing the residual coolant back to the liquid storage tank 3. The high-pressure air circuit 6 can not only avoid blockage of the outflow and inflow pipes, but also recover the coolant in time to avoid waste of coolant.

[0033] As another embodiment, the high-pressure gas circuit 6 includes a plurality of branch pipes 61 and a main gas circuit pipe 62, wherein the plurality of branch pipes 61 are connected to a plurality of coolant outflow pipes 11 or a plurality of coolant return pipes 12, and the main gas circuit pipe 62 is connected to the plurality of branch pipes 61, and an air inlet 621 is provided at one end of the main gas circuit pipe 62. The operating principle of the high-pressure gas circuit 6 is as follows: when the high-pressure gas circuit 6 of the coolant outflow pipe 11 is opened, high-pressure gas is filled into the air inlet 621 of the main gas circuit pipe 62, and the high-pressure gas simultaneously flows into the plurality of branch pipes 61 to flush the coolant remaining inside the outflow pipe into the external device, and then flushes back from the external device into the inflow pipe, and finally flows back to the liquid storage tank 3 again. Conversely, opening the high-pressure gas circuit 6 of the coolant inflow pipe can also achieve the same effect.

[0034] As an embodiment, the branch pipe 61 is provided with a second valve 611. The branch pipe 61 can be filled with high-pressure gas in advance, and when the second valve 611 is opened, an impact force can be generated, which is more convenient for blowing the coolant remaining in the coolant outflow pipe 11 or the coolant return pipe 12 back to the storage tank.

[0035] As an embodiment, a heat dissipation fan 15 is provided on the top of the chassis 1. The heat dissipation fan 15 is used to transfer the heat inside the chassis 1 in time to reduce the potential safety hazards.

[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
