Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chillers, and in particular to a water-cooled chiller. Background Technology
[0002] Water-cooled chillers, also known as water-cooled box-type industrial chiller units, are devices used in various industries to achieve process objectives through cooling. They are widely used in industries such as medical, food, biological, chemical, laser, metallurgy, machinery, electroplating, and processing. Their core function is to precisely control the temperature of heat-generating equipment through a circulating cooling medium (such as water or coolant), ensuring that the equipment operates within a stable temperature range.
[0003] Water-cooled chillers mainly consist of components such as a compressor, condenser, evaporator, and expansion valve. During operation, the compressor compresses the refrigerant into a high-temperature, high-pressure gas. This gas enters the condenser, where it exchanges heat with the cooling water, dissipating heat into the water and cooling the refrigerant into a liquid. The liquid then passes through the expansion valve, where it is depressurized and becomes a low-temperature liquid before entering the evaporator. In the evaporator, this low-temperature liquid exchanges heat with the water, absorbing heat and lowering the water temperature. The low-temperature, low-pressure refrigerant vapor is then drawn back into the compressor, and the cycle repeats, achieving continuous cooling. Currently, chillers generally have a water tank. Some models place the evaporator inside the tank, directly exchanging heat with the water. However, after prolonged use, scale easily accumulates in the tank, requiring periodic disassembly and cleaning, which is quite inconvenient. Utility Model Content

A drain valve is installed at the bottom of one side of the water tank. Multiple nozzles are installed on the side wall of the other side of the water tank. The water outlet of each nozzle faces the bottom of the inner wall of the water tank. Each nozzle is connected to a water pipe.
[0007] Preferably, the nozzles are configured as five, and the five nozzles are arranged at intervals in the horizontal direction.
[0008] Preferably, the water tank is provided with a connecting pipe, one end of which extends to the outside of the water tank, and the end of the connecting pipe is provided with an external thread. The nozzle is provided with a threaded sleeve, and the threaded sleeve is threadedly connected to the connecting pipe.

[0012] Preferably, the water tank has a cover at the top, and the inner wall of the water tank has a raised edge. The cover is supported on the raised edge, and multiple bolts are threadedly connected between the cover and the raised edge.
[0013] In summary, this utility model includes at least one of the following beneficial technical effects of a water-cooled chiller:
[0014] When a lot of dirt accumulates at the bottom of the water tank, first open the drain valve to empty the water inside the tank. Then, the water pipe supplies water to the nozzle through the connecting pipe. The nozzle sprays water to flush away the dirt, thus removing the dirt from the water tank. The dirt is carried by the water and flows to the drain valve under the action of gravity, and then the dirt can be discharged out of the water tank. Cleaning is convenient and quick.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] This utility model discloses a water-cooled chiller, such as... Figure 1-4 As shown, the device includes a housing 1, in which a compressor, a condenser 2, an evaporator, and a water tank 3 are fixedly installed. The evaporator is fixedly installed inside the water tank 3. Five nozzles 32 are fixedly installed on one side wall of the water tank 3, and the five nozzles 32 are arranged at intervals along the horizontal direction.
[0023] Meanwhile, five connecting pipes 33 are fixedly welded to the water tank 3. One end of the connecting pipe 33 extends to the outside of the water tank 3, and the end of the connecting pipe 33 extending into the water tank 3 has an external thread on its circumference. A threaded sleeve is welded to the nozzle 32, and the threaded sleeve is threadedly connected to the connecting pipe 33. The end of the connecting pipe 33 outside the water tank 3 is connected to a water pipe. When a lot of dirt accumulates inside the water tank 3, the water pipe supplies water to the nozzle 32 through the connecting pipe 33. The nozzle 32 sprays water to flush away the dirt, thereby removing the dirt from the water tank 3. At the same time, the connecting pipe 33 is set at an angle, with the lower end of the connecting pipe 33 facing the bottom of the inner wall of the water tank 3. In this way, after the nozzle 32 is installed on the connecting pipe 33, the water outlet of the nozzle 32 faces the bottom of the inner wall of the water tank 3, which can better flush away the dirt at the bottom of the water tank 3.
[0024] Additionally, a drain valve 31 is connected to the bottom of one side of the water tank 3. The bottom of the inner wall of the water tank 3 is inclined, with the nozzle 32 located on the higher side of the bottom of the water tank 3 and the drain valve 31 located on the lower side of the bottom of the water tank 3. When the nozzle 32 washes away dirt, the dirt is carried by the water and flows to the drain valve 31 under the action of gravity, thus facilitating the discharge of dirt from the water tank 3. Furthermore, a conical funnel 34 is welded to the lower side of the bottom of the water tank 3. The larger end of the conical funnel 34 is connected to the water tank 3, and the drain valve 31 is fixedly installed on the smaller end of the conical funnel 34. The conical funnel 34 can better collect the flushed dirt, thus allowing for more thorough discharge of the dirt.
[0025] In addition, a cover 35 is provided on the top of the water tank 3, and a flange 36 is welded around the inner wall of the water tank 3. The cover 35 is supported on the flange 36. Multiple bolts are threaded between the cover 35 and the flange 36. When maintenance personnel need to inspect the inside of the water tank 3, they can unscrew the bolts between the cover 35 and the flange 36 to open the cover 35 and thus repair the condenser 2 inside the water tank 3.
[0026] The implementation principle of a water-cooled chiller according to this utility model embodiment is as follows: When a lot of dirt is deposited at the bottom of the water tank 3, firstly, the drain valve 31 is opened to drain the water inside the water tank 3. Then, the water pipe supplies water to the nozzle 32 through the connecting pipe 33. The nozzle 32 sprays water to flush away the dirt, thereby washing away the dirt in the water tank 3. The dirt is carried by the water and flows to the drain valve 31 under the action of gravity. Then the dirt can be discharged from the water tank 3. Cleaning is convenient and quick.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
