[0002] In water treatment equipment with refrigeration capabilities, heat exchangers are typically used to absorb and remove heat from the heat dissipation end of the internal refrigeration unit 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 heat dissipation end of the refrigeration unit. Typically, heat exchangers only have a single inlet, making it impossible to connect multiple pipelines supplying different types of heat exchange coolants simultaneously, resulting in low heat exchange efficiency.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] like Figure 3 The heat exchanger 100 shown includes a main body 11, at least two inlet connectors 12, and at least two outlet connectors 13. The main body 11 is installed inside a water treatment device and has an internal heat exchange channel 101 for the flow of heat exchange coolant. The inlet connectors 12 and 13 are both connected to the main body 11 and are connected through the heat exchange channel 101. It should be noted that the main body 11 is used to absorb heat from the heat dissipation end 301 of the refrigeration device 300 (usually a compressor refrigeration mechanism or a semiconductor refrigeration mechanism) in the water treatment device. The heat exchange coolant is a liquid that easily absorbs heat, such as water or liquid ammonia. The inlet connectors 12 and 13 are a common water connection structure, which can be integrally molded with the main body 11 or installed on the main body 11 by welding, threaded connection, or other methods.

[0037] See also Figure 3As understood, through the above design, multiple inflow connectors 12 can simultaneously connect to multiple heat exchanger coolant source pipelines; specifically, one inflow connector 12 is used to connect to the heat exchanger tank 400, and another inflow connector 12 is used to connect to external water sources such as tap water. The heat exchanger tank 400 can hold liquids such as liquid ammonia with a heat absorption rate greater than that of water, thereby increasing the heat absorption rate of the heat exchanger 100. In practical use, the heat exchanger 100 can use various heat exchanger coolants according to actual needs, thereby improving the heat exchange performance of the heat exchanger 100.

[0038] The technical details of each component will be introduced below.

[0039] In some embodiments, the main body 11 has at least two heat exchange channels 101 inside, and the heat exchange channels 101 are not interconnected. Please refer to [link / reference]. Figure 2 , Figure 3 To understand this, when the heat exchange tank 400 contains a heat exchange coolant with a heat absorption rate greater than that of water (for ease of understanding, liquid ammonia will be used as an example of the heat exchange coolant below, but this does not limit the scope of this application), it is understood that liquid ammonia cannot be mixed with water, otherwise it will affect the heat absorption performance of the liquid ammonia. By setting non-connected heat exchange cavities 101 inside the main body 11, different types of heat exchange coolants can flow separately within the cavities without mixing, thus ensuring the stability of the heat exchange performance of the heat exchanger 100.

[0040] Correspondingly, such as Figure 4 , Figure 5 , Figure 6 As shown, each heat exchange channel 101 is connected to an inlet connector 12 at one end and an outlet connector 13 at the other end. In this way, at least two independent heat exchange coolant flow lines can be formed, avoiding the mixing of different types of heat exchange coolants.

[0041] In some other embodiments, the main body 11 has at least two heat exchange channels 101 inside, and the at least two heat exchange channels 101 are connected. When the heat exchange coolant contained in the heat exchange tank 400 is water, it can be mixed with external tap water without affecting the heat exchange performance of the heat exchanger 100. Since the heat exchange channel 101 connected to the hot water tank is connected to the heat exchange channel 101 connected to the tap water, tap water can also enter the hot water tank through the heat exchange channel 101, thereby replenishing the water in the heat exchange tank 400 in the above manner when the water in the heat exchange tank 400 is insufficient.

[0042] In some implementations, at least two inlet connectors 12 are used to connect the same or different hot water exchange circuits.

[0043] like Figure 3 , Figure 5 , Figure 6 As shown, the heat exchanger 100 provided in this application is provided with two inlet connectors 12. Preferably, the two inlet connectors 12 are connected to different heat exchange water circuits. Specifically, one inlet connector 12 of the heat exchanger 100 is connected to an external tap water source, and the other inlet connector 12 is connected to the heat exchange liquid tank 400, so that heat exchange can be carried out simultaneously using two heat exchange water circuits.

[0044] Of course, the two inlet connectors 12 can also be connected to the same heat exchanger circuit. Specifically, both inlet connectors 12 are connected to the heat exchanger tank 400.

[0045] In some implementations, please refer to Figure 5 , Figure 6 To understand this, the main body 11 has two heat exchange channels 101 inside, namely the first channel 1011 and the second channel 1012, which are independently spaced from each other. Figure 5 The dashed line in the diagram represents the flow path of the first cavity 1011. Figure 6 The dashed line in the diagram represents the flow path of the second cavity 1012. Correspondingly, the main body 11 has a first part 111 and a second part 112 for accommodating water flow connectors (i.e., inlet connector 12 and outlet connector 13). The two ends of the first cavity 1011 and the second cavity 1012 are respectively located in the first part 111 and the second part 112. The inlet connector 12 and the outlet connector 13, communicating with the first cavity 1011, are respectively located in the first part 111 and the second part 112, while the inlet connector 12 and the outlet connector 13, communicating with the second cavity 1012, are respectively located in the second part 112 and the first part 111. Through this design, the flow directions of the heat exchange coolant in the first cavity 1011 and the second cavity 1012 are opposite (see [reference]). Figure 5 and Figure 6 (The dashed lines in the diagram represent the flow paths of the first cavity 1011 and the second cavity 1012.) It is understood that when the heat exchange coolant first enters the heat exchange cavity 101, its temperature is at its lowest. It rapidly absorbs heat from the surrounding main body 11, causing a rapid drop in the local temperature of the main body 11. Through the above design, the main body 11 can be cooled simultaneously from both the first part 111 and the second part 112, resulting in a more uniform overall temperature change and improving the heat exchange performance of the heat exchanger 100.

[0046] In some embodiments, the first part 111 and the second part 112 are located on adjacent or opposite sides of the main body 11 to increase the distance between the first part 111 and the second part 112, thereby increasing the distance between the two inflow connectors 12, so that the temperature change of the main body 11 is more uniform.

[0047] like Figure 3As shown, in some other embodiments, the first part 111 and the second part 112 are located at opposite ends on the same side of the main body 11. Being located on the same side of the main body 11 facilitates the connection of pipelines during the production process, and the fact that the first part 111 and the second part 112 are located at opposite ends on the same side of the main body 11 can increase the spacing between the two inflow connectors 12 and improve the uniformity of temperature changes in the main body 11.

[0048] It is understandable that the uniform temperature change of the main body 11 can evenly absorb the heat from the heat dissipation end 301 of the cooling device 300 in the water treatment equipment, and will not cause the temperature of the heat dissipation end 301 to be locally high or locally low, thus improving the heat exchange performance of the heat exchanger 100.

[0049] In some embodiments, a plurality of lumens 01 are evenly spaced along the length or width of the main body 11. The plurality of lumens 01 are counted along the arrangement direction of the plurality of lumens 01, and an even number of lumens 01 are connected end to end to form a first cavity 1011, and an odd number of lumens 01 are connected end to end to form a second cavity 1012.

[0050] like Figure 3 , Figure 4 As shown, multiple cavities 01 are evenly spaced along the width direction of the main body 11. It can be understood that through the above design, the flow path of the first cavity 1011 or the second cavity 1012 can be evenly distributed on the overall structure of the main body 11. In this way, even if the type and temperature of the heat exchange coolant flowing through the first cavity 1011 and the second cavity 1012 are different, the overall temperature change of the main body 11 will be very uniform, and it can evenly absorb the heat from the heat dissipation end 301 of the refrigeration device 300 in the water treatment equipment.

[0051] like Figure 1 , Figure 2 As shown, the water treatment equipment provided in this application includes the aforementioned heat exchanger 100, a cold water tank 200, a refrigeration device 300 for cooling the water inside the cold water tank 200, and a heat exchange fluid tank 400 for holding the heat exchange coolant. The cold water tank 200 is connected to the refrigeration device 300, which has a cooling end and a heat dissipation end 301, with the cooling end at least partially disposed inside the cold water tank 200. Typically, the refrigeration device 300 can be a compressor refrigeration mechanism or a semiconductor refrigeration mechanism.

[0052] like Figure 2As shown, the heat dissipation end 301 is connected to the heat exchanger 100. To improve the heat absorption efficiency of the heat exchanger 100 to the heat dissipation end 301, thermally conductive adhesive can be filled between the heat exchanger 100 and the heat dissipation end 301 to enhance the adhesion and thermal conductivity between the side of the heat exchanger 100 and the heat dissipation end 301. The heat exchanger 100 can also be connected to the heat dissipation end 301 by screws and pressed together to further improve the thermal conductivity between the two.

[0053] The aforementioned heat exchanger tank 400 is connected to at least one inlet connector 12.

[0054] The processing equipment provided in this application, by employing the aforementioned heat exchanger 100, can effectively improve the heat dissipation efficiency of the heat dissipation end 301 of the refrigeration device 300.

[0055] like Figure 2 As shown, the above-mentioned water treatment equipment also includes an inlet 02 for connecting to an external tap water source. The inlet 02 is connected to the heat exchanger 100 through the inlet connector 12. The external water source enters the water treatment equipment through the inlet 02 and then flows through the heat exchanger 100 to absorb the heat from the heat dissipation end 301.

[0056] In some embodiments, the cold water tank 200 is connected to at least one inlet connector 12. In actual use, when the cold water in the cold water tank 200 has not been used for a long time, the quality of the cold water will deteriorate and it will no longer be drinkable. With the above design, the cold water with deteriorated quality can be discharged into the heat exchanger 100 through the pump body to participate in heat exchange, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0057] In some other implementations, such as Figure 2 As shown, the cold water tank 200 is connected to the heat exchange fluid tank 400 (not shown in the figure). In actual use, when the cold water in the cold water tank 200 has not been used for a long time, the quality of the cold water will deteriorate and it will no longer be drinkable. With the above design, the deteriorated cold water can be pumped into the heat exchange fluid tank 400 for storage. The temperature of the cold water is very low, and entering the heat exchange fluid tank 400 will lower the temperature of the heat exchange coolant in the heat exchange fluid tank 400, thereby better absorbing the heat from the heat dissipation end 301, improving the water utilization rate and enhancing the heat exchange performance of the heat exchanger 100.

[0058] In some implementations, such as Figure 2As shown, the water treatment equipment provided in this application also includes a filter assembly 500 for water purification. The filter assembly 500 contains a filter element and has a wastewater outlet 501 for discharging filtered wastewater (wastewater is generated during the filtration process). Normally, the wastewater is directly discharged from the water treatment equipment. In this embodiment, the wastewater outlet 501 is connected to at least one inlet connector 12; in this way, the wastewater can enter the heat exchanger 100 to participate in heat exchange, thereby removing the heat absorbed by the heat dissipation end 301 of the heat exchanger 100 and improving water utilization.

[0059] Except as described above, such as Figure 2 As shown, the wastewater outlet 501 can also be connected to the heat exchange liquid tank 400. Wastewater can enter the heat exchange liquid tank for storage to participate in heat exchange, thereby improving water utilization.

[0060] 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.

[0061] 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. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
