Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a heat exchange device and water treatment equipment. Background Technology
[0002] In water treatment equipment with refrigeration capabilities, heat exchangers are typically used to absorb and remove heat from the cooling unit's heat dissipation end in order to efficiently dissipate heat. These heat exchangers have internal channels for liquid flow; as the liquid flows through these channels, it carries away the heat absorbed by the heat exchanger, thus cooling the cooling unit's heat dissipation end. Typically, heat exchangers have only one inlet. When low-temperature hot water enters the heat exchanger, the temperature near the inlet decreases first, creating a significant temperature difference in certain areas. This uneven temperature distribution within the heat exchanger negatively impacts its cooling efficiency for the cooling unit's heat dissipation end. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0036] The present invention will now be described in further detail with reference to the accompanying drawings.
[0037] like Figure 2 , Figure 3 The heat exchange device 100 shown includes a main body 101, a first outflow connector 102, and at least two first inflow connectors 103. It should be noted that the heat exchange device 100 provided in this application is used in water treatment equipment, such as water dispensers and water purifiers. The first outflow connector 102 and the first inflow connectors 103 are used to connect to an external water circuit. Hot water flows into the main body 101 through the first inflow connectors 103 to absorb heat from the main body 101, and then flows out through the first outflow connectors 102 to carry away the heat from the main body 101.
[0038] Please refer to it again. Figure 2 , Figure 3The aforementioned main body 101 is disposed within a water treatment device and has an internal heat exchange chamber 03 for the flow of hot water. A first outflow connector 102 is connected to the main body 101 and communicates with the heat exchange chamber 03. Each first inflow connector 103 is connected to the main body 101 and communicates with the heat exchange chamber 03. Furthermore, each first inflow connector 103 communicates with a different part of the heat exchange chamber 03. In practical applications, heat from the cooling device's heat dissipation end can be transferred to the main body 101 of the heat exchange device 100 through direct contact. Hot water flows into the heat exchange chamber 03 through the first inflow connectors 103, and the heat on the main body 101 is transferred to the hot water in the heat exchange chamber 03, and finally carried away with the outflow of the hot water. The heat exchange device 100 provided in this application has at least two first inflow connectors 103 on its main body 101. The heat exchange water can flow into the heat exchange cavity 03 inside the main body 101 through the at least two first inflow connectors 103. Each first inflow connector 103 is located at a different part of the main body 101, which can make the temperature change of the main body 101 of the heat exchange device 100 more uniform and improve the heat exchange efficiency between the heat exchange device 100 and the heat dissipation end of the refrigeration device.
[0039] In addition to the aforementioned technical effects, it is understood that the overall temperature change during the heat exchange process of the heat exchange device 100 will cause thermal expansion and contraction of its structure. The heat exchange device 100 provided in this application has a more uniform overall temperature change, resulting in smaller local temperature differences compared to a heat exchange device 100 with only one hot water inlet 01. This helps protect the structure of the heat exchanger itself and extends the service life of the heat exchange device 100.
[0040] The technical details of each component will be introduced below.
[0041] In some implementations, such as Figure 3 , Figure 4 As shown, the inner wall of the heat exchange cavity 03 is provided with an outlet 02 and at least two inlets 01. The outlet 02 is the connection port between the first outlet connector 102 and the heat exchange cavity 03, and the inlets 01 are the connection ports between the first inlet connector 103 and the heat exchange cavity 03. The outlet 02 is connected to the first outlet connector 102, and the at least two inlets 01 are connected to at least two first inlet connectors 103 in a one-to-one correspondence.
[0042] Please see Figure 4 , Figure 5 To understand this, the inner wall of the heat exchange cavity 03 includes a first side wall 04 and a second side wall 05, which are arranged opposite to each other. At least two inlet inlets 01 are located at opposite ends of the first side wall 04 or the second side wall 05. This design allows for an appropriate spacing between the two inlet inlets 01, which is beneficial for ensuring a more uniform temperature change of the heat exchange device 100 as a whole during the heat exchange process.
[0043] In some other implementations, such as Figure 5 As shown, at least two inlet inlets 01 are respectively disposed on the first sidewall 04 and the second sidewall 05. It can be understood that disposing the two inlet inlets 01 on different sidewalls can also achieve the aforementioned technical effect of making the overall temperature change of the heat exchange device 100 more uniform.
[0044] In some implementation methods, see [reference] Figure 2 To understand this, at least two first inlet connectors 103 are used to connect the same or different hot water exchange circuits. In practical applications, the source of the hot water for exchange can be various. For example, the hot water can come from tap water or from a hot water exchange tank (a structure installed in water treatment equipment to store hot water for exchange); when the water treatment equipment is a water purifier, the hot water for exchange can also be wastewater generated after the water is purified by the water purifier. In summary, the heat exchange device 100 provided in this application, because it has at least two first inlet connectors 103, can accept hot water from different sources, thus achieving diversification of hot water sources for exchange and also achieving efficient water utilization. For ease of understanding, the following further explains how to achieve efficient water utilization:
[0045] When the water treatment equipment is a water purifier with a cooling function, it is well known that the water purifier will generate wastewater during the water purification process. Under normal circumstances, the wastewater will be directly discharged into the sewer. Using the heat exchange device 100 provided in this application, the wastewater can be introduced into the heat exchange chamber 03, so that the wastewater can carry away the heat from the heat dissipation end of the cooling device during the discharge process. Correspondingly, due to the participation of wastewater, the volume of hot water provided by other water circuits will be reduced, thereby achieving efficient water utilization.
[0046] In some other embodiments, at least two first inflow connectors 103 are used to connect to the same hot water tank.
[0047] In some implementations, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the heat exchange device 100 provided in this application includes an inner tube 12 and an outer tube 11, with the outer tube 11 sleeved outside the inner tube 12 to form a double-layer tube structure. A gap 06 is formed between the inner tube 12 and the outer tube 11, and the gap 06 communicates with the lumen of the inner tube 12 to form a heat exchange channel 03. In practical applications, the double-layer tube structure is more compact and has higher overall integrity.
[0048] like Figure 4 , Figure 7 , Figure 8 As shown, at least two first inlet connectors 103 connect to gap 06, and a first outlet connector 102 connects to the cavity of the inner tube 12. During the flow of hot water, the hot water first enters gap 06, carrying away the heat from the outer tube 11, and then flows along the extension direction of the outer tube 11 to the other end of the outer tube 11. Figure 4 , Figure 7 As shown, along the flow direction of the hot water in gap 06, a passage is provided between the distal end of the inner tube 12 and the distal end of the outer tube to connect gap 06 with the cavity of the inner tube 12. The heat-absorbing hot water flows into the cavity of the inner tube 12 and is then discharged. It can be understood that through the above design, it is possible to ensure that the hot water can fully absorb heat while achieving same-side inflow and same-side outflow, making the overall structure of the heat exchange device 100 more compact.
[0049] In some implementations, such as Figure 5 As shown, a limiting structure 07 is provided between the inner tube 12 and the outer tube 11 to prevent the outer wall of the inner tube 12 from contacting the inner wall of the outer tube 11. Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 A limiting structure 07 is disposed on the inner wall of the outer tube 11. The limiting structure 07 abuts against the inner tube 12, ensuring that a stable gap is maintained between the outer wall of the inner tube 12 and the inner wall of the outer tube 11, thereby maintaining the stability of the gap 06. Through the above design, the outer wall of the inner tube 12 and the inner wall of the outer tube 11 will not come into contact during the heat exchange process, ensuring the stability of the heat exchange efficiency of the heat exchange device 100.
[0050] Conversely, the aforementioned limiting structure 07 can also be set on the outer wall of the inner tube 12, achieving the same technical effect.
[0051] Understandably, since the outer tube 11 needs to contact the heat dissipation end of the refrigeration unit for heat exchange, it can be made of a material with good thermal conductivity, such as stainless steel or other metals, to absorb heat from the heat dissipation end of the refrigeration unit. Conversely, since the inner tube 12 needs to have hot water that has absorbed heat flowing through its cavity, it can be made of insulation material or a material with poor thermal conductivity, such as plastic.
[0052] like Figure 1As shown, this application provides a water treatment device including a hot water exchange tank, a refrigeration unit, a cold water tank 200, and the aforementioned heat exchange unit 100. The hot water exchange tank is connected to the heat exchange unit 100 via a first inlet connector 103 and a first outlet connector 102, and is used to store hot water for exchange. The refrigeration unit has a heat dissipation end and a cooling end; the cooling end is connected to the cold water tank 200, and the heat dissipation end is connected to the heat exchange unit 100. Typically, the refrigeration unit can be a compressor refrigeration unit or a semiconductor refrigeration unit.
[0053] In some embodiments, the hot water exchange tank includes a tank body, a second inlet connector, and a second outlet connector. Both the second inlet connector and the second outlet connector are connected to the tank body. The second inlet connector communicates with a first outlet connector 102, and the second outlet connector communicates with at least one first inlet connector 103. In this manner, a circulating water path can be formed between the hot water exchange tank and the heat exchange device 100. Correspondingly, a circulation pump is provided between the hot water exchange tank and the heat exchange device 100 to drive the hot water to circulate between them.
[0054] In some embodiments, the tank has an internal chamber, with the direction of water level rise within the chamber being the X direction. The hot water exchange tank includes at least two second outflow connectors, and both the second inflow connectors and the at least two second outflow connectors are connected to the chamber. Along the X direction, the chamber is sequentially divided into a bottom layer, a middle layer, and a top layer. The multiple second outflow connectors are connected to at least two of the bottom, middle, and top layers, respectively, and the second inflow connectors are connected to the top layer. Water from different water layers in the hot water exchange tank can be extracted using this method. The following is a detailed description:
[0055] Through the above design, the heat-absorbing hot water flows from the top layer of the chamber into the heat exchange tank. As is well known, water at different temperatures will stratify; generally (assuming the density of discharged water actually increases at 4 degrees Celsius), the hotter water will be on top, and the colder water will be on the bottom. Therefore, during the heat exchange process, the high-temperature water that has absorbed heat will collect on the top layer of the heat exchange tank, and the temperature of the hot water on the top layer will be higher than that of the middle and bottom layers. Using this method, even colder hot water can be obtained through the second outflow connectors located on the middle and bottom layers and delivered to the heat exchange device 100, thereby improving the heat exchange efficiency of the heat exchange device 100.
[0056] In some implementations, the cold water tank 200 is connected to the hot water exchange tank. When the water in the cold water tank 200 is no longer suitable for drinking or use due to prolonged storage, the cold water in the cold water tank 200 can be drained into the hot water exchange tank to cool the heat dissipation end of the refrigeration device, thereby improving the utilization rate of water.
[0057] In some other embodiments, the cold water tank 200 can be directly connected to the heat exchange device 100. When the water in the cold water tank 200 is no longer suitable for drinking or use due to prolonged storage, the cold water in the cold water tank 200 can flow directly into the heat exchange chamber 03 of the heat exchange device 100 to participate in heat exchange, thereby improving the utilization rate of water.

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.
