Traditional heat exchangers have internal channels for the flow of heat exchange coolant. These channels usually allow the heat exchange water to flow through in a straight line, resulting in low efficiency in heat transfer to the heat exchange coolant and requiring a large volume of coolant.

[0006] In some embodiments, the main body includes a first plate and a second plate disposed opposite to each other, the first plate and the second plate abutting against each other, the side of the first plate opposite to the second plate being a first surface, and the side of the second plate opposite to the first plate being a second surface;

[0008] In some embodiments, both the first surface and the second surface are provided with recesses, the recess on the first surface is a first recess, and the recess on the second surface is a second recess, and the extending directions of the first recess and the extending directions of the second recess are intersected.

[0009] In some embodiments, the heat exchange cavity is provided with an inlet and an outlet, the inlet being connected to the inflow connector and the outlet being connected to the outflow connector, and the inlet being oriented perpendicular to the first surface or the second surface.

[0010] In some embodiments, the inflow connector is used to connect to a hot water tank or other hot water source.

[0011] This application provides a water treatment device including a heat exchanger, a water cooling device, and a refrigeration device.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] like Figure 3 , Figure 4 The heat exchanger 100 shown includes a main body 11, an inlet connector 12, and an outlet connector 13. It is installed inside a water treatment device and connected to a water cooling device 200. The heat exchanger 100 has an internal heat exchange chamber 101 for the flow of heat exchange coolant. It should be noted that the heat exchanger 100 absorbs and removes heat from the heat dissipation end 301 of the refrigeration device 300 (typically a compressor refrigeration device 300 or a semiconductor refrigeration device 300) in the water treatment device. The water treatment device can be a water dispenser or a water purifier. The water cooling device 200 contains heat exchange coolant (which can be water or a liquid with a higher heat absorption rate than water, such as liquid ammonia). The water cooling device 200 supplies heat exchange coolant to the heat exchanger 100 for heat exchange within the heat exchanger 100.

[0031] Both the inflow connector 12 and the outflow connector 13 are located on the main body 11 and communicate with the heat exchange chamber 101. The inflow connector 12 and the outflow connector 13 can be connected to the main body 11 by threads, or they can be integrally molded with the main body 11 to enhance the overall integrity of the heat exchanger 100. Molding the inflow connector 12 and the outflow connector 13 integrally with the main body 11 also prevents leakage at the joint connection, enhancing the sealing performance of the main body 11.

[0032] The heat exchange cavity 101 has a fractal flow channel structure. When the heat exchange coolant flows along the heat exchange cavity 101 with the fractal flow channel structure, it fills the entire heat exchange cavity 101 at a faster speed. At the same time, the heat on the main body 11 is transferred to the heat exchange coolant at a faster speed, which enhances the rate of heat transfer to the heat exchange coolant and thus significantly improves the heat exchange efficiency of the heat exchanger 100.

[0033] The technical details of each component will be introduced below.

[0034] In some implementations, such as Figure 3 , Figure 4As shown, the heat exchange chamber 101 includes a main water passage 1011 and multiple branch water passages 1012. The multiple branch water passages 1012 are all connected to the main water passage 1011 to form a fractal flow channel structure. Each branch water passage 1012 is connected to the main water passage 1011. When the heat exchange coolant flows through the main water passage 1011, the heat exchange coolant will quickly distribute to each branch water passage 1012, and then quickly distribute throughout the entire heat exchange chamber 101, accelerating the speed at which the heat exchange coolant flows and fills the entire heat exchange chamber 101.

[0035] It should be noted that both the inlet connector 12 and the outlet connector 13 are connected to the main water passage 1011. The heat exchange coolant flows into the main water passage 1011, which is directly connected to the inlet connector 12, through the inlet connector 12, and then into each branch water passage 1012. It then flows from each branch water passage 1012 to the main water passage 1011, which is directly connected to the outlet connector 13, and finally flows out of the main body 11 of the heat exchanger 100 through the outlet connector 13.

[0036] Furthermore, each of the aforementioned branch waterways 1012 can be further branched into multiple waterways, forming a hierarchical branching structure.

[0037] In some implementations, such as Figure 4 , Figure 5 As shown, the main body 11 includes a first plate 111 and a second plate 112 arranged opposite to each other, with the first plate 111 and the second plate 112 abutting against each other. The side of the first plate 111 opposite to the second plate 112 is a first surface 01, and the side of the second plate 112 opposite to the first plate 111 is a second surface 02. Multiple recesses 03 are provided on the first surface 01 and the second surface 02, and the multiple recesses 03 are spaced apart to form multiple branch water channels 1012. The inflow connector 12 communicates with the multiple recesses 03 to form a main water channel 1011. This method allows a fractal flow channel structure to be formed inside the main body 11, improving the heat exchange efficiency of the heat exchanger 100. Simultaneously, the abutting and splicing arrangement of the first plate 111 and the second plate 112 facilitates the processing of the recesses 03.

[0038] For some other implementations, please refer to Figure 4 To understand, the first plate 111 is used for heat absorption (i.e., in practical applications, the first plate 111 is used to contact the heat dissipation end 301 of the refrigeration device 300), and the second plate 112 abuts against the first plate 111. In this embodiment, only the first plate 111 is provided with multiple recesses 03, and the first plate 111 also has a wide groove that communicates with each recess 03. The second plate 112 abuts against the first plate 111 to seal each recess 03 to form multiple branch water channels 1012, and the second plate 112 abuts against the first plate 111 to seal the wide groove to form the main water channel 1011. A fractal flow channel structure can also be formed through the above design.

[0039] In some implementations, such as Figure 5 As shown, both the first surface 01 and the second surface 02 are provided with recesses 03. The recess 03 located on the first surface 01 is the first recess 03, and the recess 03 located on the second surface 02 is the second recess 03. The extending directions of the first recess 03 and the second recess 03 are intersected. This arrangement allows the heat exchange coolant to flow more fully within the heat exchange chamber 101 as it flows along the recesses 03, thereby absorbing more heat and improving the heat exchange efficiency of the heat exchanger 100. In addition to the above effects, the recesses 03 also increase the surface area of ​​the inner wall of the heat exchange chamber, that is, increase the contact area between the heat exchange coolant and the main body 11, improving the efficiency of heat transfer from the main body 11 to the heat exchange coolant.

[0040] In some implementations, such as Figure 4 , Figure 5 As shown, the heat exchange chamber 101 is provided with an inlet 1013 and an outlet 1014. The inlet 1013 is connected to the inflow connector 12, and the outlet 1014 is connected to the outflow connector 13. The orientation of the inlet 1013 is perpendicular to the first surface 01 or the second surface 02. According to Figure 4 , Figure 5 As shown, the inlet 1013 is oriented perpendicular to the first surface 01. With this design, when the heat exchange coolant enters, it can impact the various recesses 03 provided on the first surface 01 in a direction perpendicular to the first surface 01 (the interval between the inlet 1013 and the recesses 03 is the main water passage 1011, and each recess 03 forms a branch water passage 1012). This ensures that each recess 03 can uniformly receive the heat exchange coolant from the inlet 1013, making the flow rate of the heat exchange coolant flowing in each branch water passage 1012 more uniform.

[0041] In some implementations, the inlet connector 12 is used to connect to the hot water tank 21 or other hot water source.

[0042] Please see Figure 2 To understand this, the heat exchange water source (i.e., the source of the heat exchange coolant) can be multiple, such as the heat exchange water tank 21, an external water source, or a cold water tank 400. Setting up multiple heat exchange water sources can help ensure the continuous and stable operation of the heat exchange process of the heat exchanger 100. That is, if one of the heat exchange water sources fails, the heat exchanger 100 can still obtain heat exchange coolant through other means to ensure the smooth operation of the heat exchange process.

[0043] like Figure 1 , Figure 2As shown, the water treatment equipment provided in this application includes the aforementioned heat exchanger 100, water cooling device 200, and refrigeration device 300. The water cooling device 200 includes a heat exchange tank 21 for holding heat exchange coolant. The heat exchange tank 21 has an inlet 201 for the heat exchange coolant to flow in and an outlet 202 for the heat exchange coolant to flow out. The inlet 201 is connected to the outlet connector 13, and the outlet 202 is connected to the inlet connector 12. The refrigeration device 300 has a heat dissipation end 301, and the main body 11 of the heat exchanger 100 is connected to the heat dissipation end 301. It should be noted that the above-mentioned water treatment equipment can be a water dispenser or water purifier with a refrigeration function. As is well known, the refrigeration device 300 generates heat during the refrigeration process. In order to ensure the refrigeration effect of the refrigeration device 300, it is necessary to dissipate the heat in a timely manner. This water treatment equipment uses the heat exchanger 100 provided in this application, which can efficiently absorb and transfer the heat generated by the refrigeration device 300, thereby improving the refrigeration performance of the water treatment equipment.

[0044] In some implementations, such as Figure 1 , Figure 2 As shown, the water treatment equipment provided in this application also includes a cold water tank 400, and the refrigeration device 300 has a refrigeration end connected to the cold water tank 400. It should be noted that the cold water tank 400 is used to hold cold water, which is formed by the refrigeration effect of the refrigeration device 300 on room temperature water and stored in the cold water tank 400.

[0045] Please see Figure 2 The cold water tank 400 is connected to the heat exchange chamber 101, which has a fractal flow channel structure, via the hot water tank 21. In actual use, when the cold water in the cold water tank 400 has not been used for a long time, its quality will deteriorate and it will no longer be suitable for drinking or use. The above design allows the degraded cold water to be pumped into the hot water tank 21 for storage as heat exchange coolant. The cold water is very cold; its entry into the hot water tank 21 lowers the temperature of the heat exchange coolant, allowing it to better absorb heat from the heat dissipation end 301, thus improving water utilization and enhancing the heat exchange performance of the heat exchange device.

[0046] It is understandable that the cold water tank 400 can also be connected to the heat exchange chamber 101 with a fractal flow channel structure through the inlet connector 12. That is, after the cold water in the cold water tank 400 becomes less drinkable or usable due to quality deterioration, it can be directly discharged by the pump body through the inlet connector 12 into the heat exchange chamber 101 inside the main body 11 of the heat exchanger 100 to participate in the heat exchange process, thereby improving the water utilization rate and enhancing the heat exchange performance of the heat exchanger 100.

[0047] In some implementations, such as Figure 1 , Figure 2The water treatment equipment provided in this application also includes a filtration device 500, which has a wastewater outlet 501 for discharging filtered wastewater. Typically, the filtration device 500 includes a filter element; the filter element generates wastewater after filtering water, and the wastewater is discharged through the wastewater outlet 501.

[0048] Please refer to it again. Figure 1 , Figure 2 As shown, the wastewater outlet 501 is connected to the heat exchange chamber 101, which has a fractal flow channel structure, through the heat exchange tank 21. Wastewater can flow into the heat exchange tank 21 for storage as heat exchange coolant, thereby improving the water utilization rate of the water treatment equipment.

[0049] It is understandable that, such as Figure 2 As shown, the wastewater outlet 501 can also be connected to the heat exchange chamber 101, which has a fractal flow channel structure, through the inflow connector 12. Wastewater can be directly discharged from the pump body into the heat exchange chamber 101 inside the main body 11 of the heat exchanger 100 through the inflow connector 12 to participate in the heat exchange process, thereby realizing the utilization of wastewater and improving the water utilization rate of the water treatment equipment.

[0050] In some implementations, such as Figure 2 As shown, the water treatment equipment provided in this application also includes an inlet valve 600 for connecting to an external water source (e.g., tap water). The inlet valve 600 is connected to the heat exchange chamber 101, which has a fractal flow channel structure, via an inlet connector 12. The external water source can enter the heat exchange chamber of the heat exchanger body 11 through the inlet connector 12 to absorb the heat transferred from the heat dissipation end 301 of the refrigeration device 300 on the heat exchanger body 100 as a heat exchange coolant. When the refrigeration device 300 is in cooling operation, the external water source can be directly used as the heat exchange coolant through the above design.

[0051] It is understood that the external water source can also be connected to the heat exchange chamber 101, which has a fractal flow channel structure, through the heat exchange tank 21. The external water source can enter the heat exchange tank 21 for storage to form heat exchange coolant, which can be replenished when the heat exchange coolant in the heat exchange tank 21 is insufficient, through the above design.

[0052] like Figure 2 As shown, the aforementioned hot water exchange tank 21 also has an exhaust port 203 for discharging excess gas and an emptying port 204 for emptying the hot water exchange tank 21. When the hot water exchange tank 21 is replenished with water, excess gas is discharged through the exhaust port 203. When the quality of the heat exchange coolant inside the hot water exchange tank 21 decreases or the temperature becomes too high to participate in the heat exchange process, the hot water exchange tank 21 discharges the heat exchange coolant inside that is no longer suitable for participating in the heat exchange process through the emptying port 204.

[0053] In summary, the heat exchanger 100 provided in this application adopts a fractal flow channel design, which improves the heat exchange efficiency of the heat exchanger 100. Accordingly, the water treatment equipment provided in this application, using the heat exchanger 100 provided in this application, can quickly cool the heat dissipation end 301 of the refrigeration device 300, thereby improving the cooling effect.

[0054] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
