In one embodiment, as shown in fig. 1, a water source cooling device comprises: heating means 100, cold water tank 200 and heat exchange tube 300. The heating mechanism 100 is provided with a heating water inlet pipe 110 and a water outlet pipe 120, and the heating water inlet pipe 110 is communicated with the cold water tank 200. The heat exchange pipe 300 is disposed outside the water outlet pipe 120, and both ends of the heat exchange pipe 300 are connected to the cold water tank 200. Specifically, the heating mechanism 100 is a heater. A water storage tank is arranged in the heater, and the water storage tank is a stainless steel heat insulation box. That is, the water source is heated by the heater, and the hot water can be effectively stored in the heat insulation box. More specifically, the heat exchange pipe fitting 300 is a plastic pipe, that is, the plastic pipe is wound around the outside of the water outlet pipe 120, and as the number of winding turns of the plastic pipe on the water outlet pipe 120 increases, the heat exchange area between the heat exchange pipe fitting 300 and the water outlet pipe 120 also increases continuously. Since the cold water tank 200 directly stores the external cold water. Therefore, the heat exchange pipe 300 is connected to the cold water tank 200, so that when the heat exchange pipe 300 exchanges heat with the water outlet pipe 120, the cold water flowing and circulating inside the heat exchange pipe 300 can be ensured, and the temperature rise after the heat exchange between the cold water and the hot water is effectively avoided. This is just one of the embodiments, for example: in order to improve the heat exchange effect, a stainless steel radiating fin can be additionally arranged between the heat exchange pipe fitting 300 and the water outlet pipe 120, and the heat exchange efficiency between the heat exchange pipe fitting 300 and the water outlet pipe 120 can be improved due to the higher metal radiating efficiency.

When the water source cooling device is used, the water source cooling device is firstly arranged in the water dispenser. And then the water source is injected into the cold water tank 200. A portion of the water is introduced into the heating mechanism 100 through the water inlet pipe 110 for heating treatment. Then, after the water source is changed into hot water by the heating mechanism 100, the hot water is discharged through the water outlet pipe 120. The winding can carry out the circulation flow of cold water in the outside heat transfer pipe fitting 300 of outlet pipe 120, and at this moment, hot water can carry out the heat transfer with the inside cold water of heat transfer pipe fitting 300 at the inside in-process that flows of outlet pipe 120 to the cooling to hot water has been realized. The hot water can be changed into cold boiled water without being taken out of the water dispenser, and the using effect of the water dispenser and the water source cooling device is improved.

In one embodiment, the heat exchange pipe member 300 includes a heat exchange water inlet pipe 310, a heat exchange spiral pipe 320, and a heat exchange water outlet pipe 330. One end of the heat exchange water inlet pipe 310 is connected with the cold water tank 200, one end of the heat exchange water outlet pipe 330 is connected with the cold water tank 200, the heat exchange spiral pipe 320 is sleeved outside the water outlet pipe 120, and the other end of the heat exchange water inlet pipe 310 and the other end of the heat exchange water outlet pipe 330 are equally divided and respectively connected with two ends of the heat exchange spiral pipe 320. Specifically, in this embodiment, the heat exchange water inlet pipe 310, the heat exchange spiral pipe 320 and the heat exchange water outlet pipe 330 are integrally formed. Since the heat exchange pipes 300 have different thicknesses or pipe diameters, the heat exchange efficiency of hot water and cold water may be affected. Therefore, the number of turns of the heat exchanging coil 320 can be increased or decreased reasonably according to actual working conditions. This is just one example of an embodiment, for example: a plurality of heat exchange openings are sequentially formed in the height direction of the heat exchange spiral pipe (from one end of the heat exchange spiral pipe to the other end of the heat exchange spiral pipe), and pistons are arranged on the heat exchange openings. Since the cold water tank 200 is always storing normal temperature water, the temperature of the normal temperature water may be affected by the change of the weather temperature. Therefore, when the outdoor temperature is high, the temperature of the water inside the cold water tank 200 is relatively increased, and at this time, the connection position of the heat exchange outlet pipe 330 and the spiral pipe may be set to achieve a predetermined heat exchange effect. Namely, a more proper heat exchange port is selected for connection. When the heat exchange outlet pipe 330 extends into the heat exchange port, the heat exchange area between the heat exchange pipe 300 and the outlet pipe 120 changes. That is to say, the above embodiment can deal with the change of the water temperature of the cold water tank 200 by changing the heat exchange area between the heat exchange pipe fitting 300 and the water outlet pipe 120, and the heat exchange effect of the water source cooling device is ensured.

In one embodiment, the water source cooling device further comprises a heat sink 340. The heat sink 340 is sleeved outside the heat exchange water outlet pipe 330. The water source cooling device also includes a fan 350. The fan 350 is disposed corresponding to the heat sink 340. The water source cooling device further comprises a water pump 360. The water pump 360 is installed on the heat exchange water outlet pipe 330. Specifically, the heat sink 340 is a metal heat sink or a metal heat sink sleeve. According to practical situations, in order to further improve the heat exchange efficiency between the cold water and the hot water, a heat exchange fan 350 may be additionally disposed at the attachments of the heat exchange pipe 300 and the water outlet pipe 120. More specifically, the water pump 360 is located at one end of the heat exchange outlet pipe 330 close to the cold water tank 200, so as to ensure that the water source inside the heat exchange pipe 300 can flow through the heat exchange coil 320 under the driving of the water pump 360. In this embodiment, the water source is driven by the water pump 360 to firstly enter the heat exchange spiral pipe 320 through the heat exchange water inlet pipe 310, then enter the heat exchange water outlet pipe 330 through the heat exchange spiral pipe 320, and finally enter the cold water tank 200 through the heat dissipation member 340 on the heat exchange water outlet pipe 330. This is just one example of an embodiment, for example: the water pump 360 is installed on the heat exchange water outlet pipe 330, and the water pump 360 is located between the heat sink 340 and the heat exchange spiral pipe 320. Above-mentioned this kind of mounting means, on the one hand can guarantee that the inside water source of heat transfer pipe fitting 300 can flow through heat transfer spiral pipe 320 fast, and on the other hand, the water source can corresponding reduction of velocity of flow behind water pump 360 to make the water source have more time and heat sink 340 to act on, improved the radiating effect of heat sink 340.

In one embodiment, the water pump 360 is additionally disposed on the heat exchange water outlet pipe 330 to effectively accelerate the circulation of the water source between the heat exchange pipe 300 and the cold water tank 200, and to effectively prevent the water source from heating up too fast when exchanging heat with hot water.

As shown in fig. 1 and 2, in one embodiment, the water outlet pipe 120 includes a first water outlet pipe 121, a second water outlet pipe 122 and a sleeve 123. The first moisture pipe 121 is connected with one end of the sleeve 123, the other end of the first moisture pipe 121 is connected with the heating mechanism 100, one end of the second moisture pipe 122 is connected with the other end of the sleeve 123, the sleeve 123 is provided with a first mounting hole 124 and a second mounting hole 125, the heat exchange spiral pipe 320 is arranged inside the sleeve 123, the heat exchange water inlet pipe 310 penetrates through the first mounting hole 124 and the heat exchange spiral pipe 320, and the heat exchange water outlet pipe 330 penetrates through the second mounting hole 125 and the heat exchange spiral pipe 320. Specifically, in this embodiment, the heat exchanging spiral pipe 320 is sleeved inside the water outlet pipe 120 through the sleeve 123. After the heating mechanism 100 heats the water source to hot water, the hot water enters the sleeve 123 through the first water outlet branch pipe 121, and at this time, the hot water exchanges heat with the cold water inside the heat exchange spiral pipe 320 inside the sleeve 123. In the above embodiment, only one layer of wall of the heat exchanging spiral pipe 320 is provided between the hot water and the cold water, compared to the heat exchanging pipe 300 sleeved outside the water outlet pipe 120. This embodiment further narrows the distance between the cold water and the hot water, thereby improving the heat exchange efficiency of the cold water and the hot water.

As shown in fig. 1, in one embodiment, the water source temperature reducing device further includes a first temperature sensor 400 and a second temperature sensor 500. The first temperature sensor 400 is mounted on the cold water tank 200, the second temperature sensor 500 is mounted on the water outlet pipe 120, and the second temperature sensor 500 is located at one end of the water outlet pipe 120 far away from the heating mechanism 100. Specifically, in this embodiment, after the cold water and the hot water exchange heat for multiple times, the temperature of the cold water is increased accordingly. Therefore, the cooling effect of cold water on hot water is ensured. The first temperature sensor 400 is additionally installed on the cold water tank 200, so that the temperature of water inside the cold water tank 200 can be monitored. When the temperature of the water inside the cold water tank 200 is higher than the room temperature. The drinking water dispenser injects a part of normal temperature water in the external water tub into the cold water tank 200, thereby achieving cooling of the cold water tank 200. More specifically, the second temperature sensor 500 is installed at one end of the water outlet pipe 120 far away from the heating mechanism 100. Namely, the temperature of the water source after heat exchange is detected by the second temperature sensor 500. A valve (not labeled) is further disposed at one end of the water outlet pipe 120 far away from the heating mechanism 100, and the valve is electrically connected to the second temperature sensor 500. When hot water reaches preset temperature after heat exchange, the water source can loop through the second temperature sensor 500 and the valve to flow out. When hot water does not reach the preset water temperature after heat exchange, the second temperature sensor 500 blocks the outflow of a water source through a control valve. At the moment, the water source continuously exchanges heat with the cold water which circularly flows until the temperature of the water source reaches the preset temperature. And finally flows out through the second temperature sensor 500 and the valve in sequence.

As shown in fig. 1 and 3, in one embodiment, the heat exchange tube 300 further includes a first water pipe 380, a second water pipe 390 and a plurality of capillary tubes 370. The first water pipe 380 is provided with a plurality of first capillary holes (not shown) corresponding to the capillary 370, and the second water pipe 390 is provided with a plurality of second capillary holes (not shown) corresponding to the capillary 370. The first water pipe 380 and the second water pipe 390 are spaced inside the casing 123, and the heat exchange water inlet pipe 310 is communicated with the first water pipe 380 through the first mounting hole 124. The heat exchange water outlet pipe 330 is connected to the second water pipe 390 through the second mounting hole 125. The plurality of capillary tubes 370 are disposed at intervals between the first water duct 380 and the second water duct 390. Specifically, in this embodiment, cold water enters the first water pipe 380 through the heat exchange water inlet pipe 310, is guided into the plurality of capillary tubes 370 through the first water pipe 380, and finally flows to the cold water tank 200 through the second water pipe 390 and the heat exchange water outlet pipe 330 in sequence. In the above entire process, the cold water passes through the capillary 370 to form a plurality of independent cold water columns, which can be sufficiently contacted with the hot water inside the sleeve 123, thereby realizing heat exchange between the cold water and the hot water.

As shown in fig. 1 and 4, in one embodiment, the water source cooling device further comprises a partition 210. The partition board 210 is movably installed inside the cold water tank 200, the partition board 210 is electrically connected with the temperature sensor, an external water pipe is further arranged on the cold water tank 200, the external water pipe and the heat exchange water inlet pipe 310 are both located on the same side of the partition board 210, and the heat exchange water outlet pipe 330 is located on the other side of the partition board 210. Specifically, in this embodiment, a driving motor is disposed on the cold water tank 200, the driving motor is connected to the partition 210, and the driving motor is electrically connected to the temperature sensor. When the temperature inside the cold water tank 200 is higher than the room temperature, the partition 210 rotates inside the cold water tank 200, thereby accelerating the cooling of cold water. More specifically, when the partition 210 is stationary, each side of the partition 210 is in one-to-one correspondence with each inner sidewall of the cold water tank 200, so that the cold water tank 200 can be divided into two independent first and

second storage tanks

220 and 230 by the partition 210. After the heat exchange tube 300 exchanges heat with the water outlet pipe 120, the temperature of the cold water inside the heat exchange tube 300 is correspondingly increased. Therefore, the heat exchange water inlet pipe 310 of the heat exchange pipe 300 is installed on the first container 220, and the heat exchange water outlet pipe 330 of the heat exchange pipe 300 is installed on the second container 230. In the above embodiment, all the cold water stored in the first receiving tank 220 is not heat-exchanged, and the cold water stored in the second receiving tank 230 is heated by heat exchange. Therefore, the above embodiment ensures that the cold water flowing out through the heat exchange water inlet pipe 310 is the cold water which is not affected by heat exchange each time, thereby ensuring the heat exchange efficiency of the heat exchange pipe 300 for the hot water.

Further, when the amount of cold water in the first receiving tank 220 is small, the partition plate 210 may be adjusted until the first receiving tank 220 and the second receiving tank 230 are communicated with each other, and the water source of the second receiving tank 230 may enter the first receiving tank 220 in a falling manner.

The heat preservation box is communicated with the heating mechanism 100 through a conduit, at the moment, one part of hot water heated by the heating mechanism 100 can exchange heat through the heat exchange water inlet pipe 310, and the other part of hot water can enter the heat preservation box through the conduit. When cold water is needed, the water dispenser can directly flow the water source of the external water tank out through the internal conduit. When the warm water is needed, the water source of the external water tank is injected into the water source cooling device, and the warm water can be obtained after the water source cooling device processes the water source.
