Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a heat exchanger and a water supply device. Background Technology

[0002] A heat exchanger (also known as a heat exchanger) is a key component in a water dispenser. Its basic function is to transfer heat between a heat exchange medium (such as a gas or liquid) and water to heat or cool the water. In existing technology, the heat exchange medium tends to flow into the medium channel near the joint, reducing its distribution in the medium channel at the joint's distal end. Similarly, water tends to flow into the water channel near the joint, further reducing its distribution in the water channel at the joint's distal end. This results in poor heat exchange performance at the joint's distal end. Utility Model Content

[0023] Example 1: like Figures 1 to 4 As shown, the heat exchanger 100 provided in this embodiment of the present invention includes a heat exchange body 10 and a water inlet connector 20, a water outlet connector 30, a heat exchange medium inlet connector 40, and a heat exchange medium outlet connector 50 connected to the heat exchange body 10. The heat exchange body 10 has a plurality of flow channels arranged in layers along a first direction XX. A portion of these flow channels is configured as a water flow channel 12a, and another portion is configured as a heat exchange medium flow channel 13a. The water flow channel 12a and the heat exchange medium flow channel 13a are isolated from each other. The water inlet connector 20 and the water outlet connector 30 are both connected to the water flow channel 12a, and the heat exchange medium inlet connector 40 and the heat exchange medium outlet connector 50 are both connected to the heat exchange medium flow channel 13a. The first direction XX is the thickness direction of the heat exchange body 10.

[0024] In use, water enters water flow channel 12a through water inlet connector 20 and then flows out of water flow channel 12a through water outlet connector 30. The heat exchange medium enters heat exchange medium flow channel 13a through heat exchange medium inlet connector 40 and then flows out of heat exchange medium flow channel 13a through heat exchange medium outlet connector 50. The water exchanges heat with the heat exchange medium in heat exchange medium flow channel 13a within water flow channel 12a to achieve heating or cooling. The water flowing out of water outlet connector 30 is the heated or cooled water.

[0025] In one embodiment, the heat exchange body 10 includes a first side 11a and a second side 11b disposed opposite to each other along a first direction XX, and the heat exchanger 100 satisfies at least one of the following conditions: 1) At least two heat exchange medium inlet joints 40 are provided, with at least one heat exchange medium inlet joint 40 provided on the first side 11a and the second side 11b respectively; 2) At least two heat exchange medium output joints 50 are provided, with at least one heat exchange medium output joint 50 provided on the first side 11a and the second side 11b respectively; 3) At least two water inlet connectors 20 are provided, with at least one water inlet connector 20 provided on the first side 11a and the second side 11b respectively; 4) At least two water output connectors 30 are provided, with at least one water output connector 30 provided on the first side 11a and the second side 11b respectively.

[0026] In this embodiment, at least two heat exchange medium inlet connectors 40 are provided, with at least one heat exchange medium inlet connector 40 provided on the first side 11a and the second side 11b respectively.

[0027] By adopting the above technical solution, at least one heat exchange medium inlet joint 40 is provided on the first side 11a and the second side 11b of the heat exchange body 10, respectively. The heat exchange medium can flow into the heat exchange body 10 from the first side 11a and the second side 11b respectively. By setting the heat exchange medium flow channel 13a to be arranged along the first direction XX, the heat exchange medium can flow into the heat exchange medium flow channel 13a from both sides of the arrangement direction of the heat exchange medium flow channel 13a. Compared with the technical solution where the heat exchange medium only flows into the heat exchange medium flow channel 13a from one side of the arrangement direction of the heat exchange medium flow channel 13a, the arrangement method of this application can make the heat exchange medium flow into each heat exchange medium flow channel 13a more evenly, thereby avoiding the situation where the amount of heat exchange medium in the far heat exchange medium flow channel 13a is small, thus helping to improve the heat exchange efficiency of the heat exchanger 100.

[0028] In one embodiment, the heat exchanger body 10 further includes a heat exchange medium inlet channel 14, which extends along a first direction XX and connects the heat exchange medium inlet connector 40 and the heat exchange medium flow channel 13a. It is understood that in other embodiments, the heat exchanger body 10 may not include the heat exchange medium inlet channel 14. For example, the heat exchange medium inlet connector 40 can be inserted into the heat exchanger body 10 along the first direction XX, and a connecting hole for the heat exchange medium flow channel 13a can be provided in the heat exchange medium inlet connector 40.

[0029] In one embodiment, the heat exchanger body 10 further includes a heat exchange medium output channel 15, which extends along a first direction XX and connects the heat exchange medium output connector 50 and the heat exchange medium flow channel 13a. It is understood that in other embodiments, the heat exchanger body 10 may not include the heat exchange medium output channel 15. For example, the heat exchange medium output connector 50 can be inserted into the heat exchanger body 10 along the first direction XX, and a connecting hole for the heat exchange medium flow channel 13a can be provided on the heat exchange medium output connector 50.

[0030] In one embodiment, the radial dimension of the heat exchange medium inlet channel 14 is greater than or equal to the radial dimension of the heat exchange medium inlet connector 40, and the radial dimension of the heat exchange medium outlet channel 15 is greater than or equal to the radial dimension of the heat exchange medium outlet connector 50. This reduces the flow resistance of the heat exchange medium, thereby promoting a more uniform distribution of the heat exchange medium into the heat exchange medium flow channels 13a and its convergence from each heat exchange medium flow channel 13a into the heat exchange medium outlet channel 15, further improving heat exchange efficiency.

[0031] For ease of description, the heat exchange medium inlet connector 40 connected to the first side 11a is defined as the first heat exchange medium inlet connector 41, and the heat exchange medium inlet connector 40 connected to the second side 11b is defined as the second heat exchange medium inlet connector 42.

[0032] In one embodiment, please refer to Figure 4 and Figure 5 The heat exchange medium input channel 14 is provided with a first heat exchange medium input connector 41 and a second heat exchange medium input connector 42, both of which are connected to the heat exchange medium input channel 14. The structure is simple and easy to manufacture. In another embodiment, at least two heat exchange medium input channels 14 are provided, with the first heat exchange medium input connector 41 and the second heat exchange medium input connector 42 respectively connected to different heat exchange medium input channels 14. For example, there are two heat exchange medium input channels 14, with the first heat exchange medium input connector 41 connected to one of the heat exchange medium input channels 14 and the second heat exchange medium input connector 42 connected to the other heat exchange medium input channel 14.

[0033] Alternatively, in another embodiment, at least two heat exchange medium input channels 14 are provided, with at least one heat exchange medium input channel 14 connected to the first heat exchange medium input connector 41 and the second heat exchange medium input connector 42. For example, two heat exchange medium input channels 14 are provided, with one heat exchange medium input channel 14 connected to the first heat exchange medium input connector 41 and the second heat exchange medium input connector 42, and the other heat exchange medium input channel 14 connected to the first heat exchange medium input connector 41.

[0034] In one embodiment, the heat exchange medium input channel 14 connects to all heat exchange medium flow channels 13a or connects to a portion of the heat exchange medium flow channels 13a. Specifically, when there is one heat exchange medium input channel 14, it connects to all heat exchange medium flow channels 13a; when there are at least two heat exchange medium input channels 14, they can connect to all or a portion of the heat exchange medium flow channels 13a. It should be noted that when the heat exchange medium input channel 14 connects to a portion of the heat exchange medium flow channels 13a, each heat exchange medium input channel 14 connects to different heat exchange medium flow channels 13a, so that the heat exchange medium input connector 40 connected to all heat exchange medium input channels 14 can connect to all heat exchange medium flow channels 13a. In this embodiment, each heat exchange medium input channel 14 connects to all heat exchange medium flow channels 13a.

[0035] In one embodiment, a single heat exchange medium output connector 50 is provided, located on either the first side 11a or the second side 11b. In this embodiment, the heat exchange medium output connector 50 is located on the first side 11a. Since only one heat exchange medium output connector 50 is provided, in order to ensure that the heat exchange medium output connector 50 connects to all heat exchange medium flow channels 13a, the heat exchange medium output channel 15 is configured to connect to all heat exchange medium flow channels 13a.

[0036] In one embodiment, a single water inlet connector 20 is provided, located on either the first side 11a or the second side 11b. In this embodiment, the water inlet connector 20 is located on the first side 11a.

[0037] In one embodiment, a single water output connector 30 is provided, located on either the first side 11a or the second side 11b. In this embodiment, the water output connector 30 is located on the first side 11a.

[0038] In one embodiment, the heat exchange body 10 further includes a water inlet channel 16 extending along a first direction XX. The water inlet channel 16 connects the water inlet connector 20 and the water flow channel 12a. It is understood that in other embodiments, the heat exchange body 10 may not include the water inlet channel 16. For example, the water inlet connector 20 can be inserted into the heat exchange body 10 along the first direction XX, and a connecting hole for the water flow channel 12a can be provided in the water inlet connector 20. In this embodiment, only one water inlet connector 20 is provided. To ensure that the water inlet connector 20 connects to all water flow channels 12a, the water inlet channel 16 is configured to connect to all water flow channels 12a.

[0039] In one embodiment, the heat exchange body 10 further includes a water outlet channel 17, which extends along a first direction XX and connects the water outlet connector 30 and the water flow channel 12a. It is understood that in other embodiments, the heat exchange body 10 may not include the water outlet channel 17. For example, the water outlet connector 30 can be inserted into the heat exchange body 10 along the first direction XX, and a connecting hole for the water flow channel 12a can be provided in the water outlet connector 30. In this embodiment, only one water outlet connector 30 is provided. To ensure that the water outlet connector 30 connects to all water flow channels 12a, the water outlet channel 17 is configured to connect to all water flow channels 12a.

[0040] In one embodiment, the radial dimension of the water inlet channel 16 is greater than or equal to the radial dimension of the water inlet connector 20, and the radial dimension of the water outlet channel 17 is greater than or equal to the radial dimension of the water outlet connector 30. This reduces the flow resistance of the water, thereby promoting a more uniform distribution of water into the water channels 12a and its convergence from each water channel 12a into the water outlet channel 17, further improving heat exchange efficiency.

[0041] In one embodiment, along the first direction XX, water flow channel 12a and heat exchange medium flow channel 13a are alternately arranged. This arrangement ensures that heat exchange medium flow channels 13a are provided on both sides of the water flow channel 12a along the first direction XX. The heat exchange medium flow channels 13a on both sides simultaneously heat the water flow within the water flow channel 12a, greatly improving the efficiency of water heating or cooling, allowing the water to reach the designated temperature more quickly, and saving heating or cooling time.

[0042] Please see Figure 4 The heat exchanger body 10 includes multiple heat exchange baffles 18, which are arranged sequentially along a first direction XX. Flow channels are formed between adjacent heat exchange baffles 18, and the outer edges of the multiple heat exchange baffles 18 are stacked and welded. Multiple heat exchange baffles 18 form multiple layers of flow channels along the first direction XX. These multiple layers of flow channels are sequentially divided into odd-numbered flow channels 13b and even-numbered flow channels 12b. The odd-numbered flow channels 13b and even-numbered flow channels 12b are interconnected, while the odd-numbered flow channels 13b and even-numbered flow channels 12b are isolated from each other. The odd-numbered flow channel 13b is one of a water flow channel 12a or a heat exchange medium flow channel 13a, and the even-numbered flow channel 12b is the other of a water flow channel 12a or a heat exchange medium flow channel 13a.

[0043] In practical applications, multiple heat exchange baffles 18 form multiple layers of flow channels along the first direction XX. These multiple layers of flow channels are further divided into odd-numbered flow channels 13b and even-numbered flow channels 12b along the first direction XX. Odd-numbered flow channels 13b include, for example, the first and third layers, while even-numbered flow channels 12b include, for example, the second and fourth layers. Odd-numbered flow channels 13b can be heat exchange medium flow channels 13a, and even-numbered flow channels 12b can be water flow channels 12a. In this way, each water flow channel 12a has heat exchange medium flow channels 13a on both sides, effectively saving the heating or cooling time of the water flow in the water flow channels 12a and increasing the speed at which the water supply device can output hot or cold water.

[0044] Please see Figure 4 The heat exchange body 10 has at least four channels penetrating each flow channel along the first direction XX. The heat exchange body 10 also includes a plurality of seals 19. A portion of the seals 19 are used to seal all even-numbered flow channels 12b within the channels to form a heat exchange medium input channel 14 and a heat exchange medium output channel 15. Another portion of the seals 19 are used to seal all odd-numbered flow channels 13b within the channels to form a water input channel 16 and a water output channel 17.

[0045] In practical applications, since the heat exchange medium is mainly used to heat or cool water, and the water needs to flow out of the water supply device for direct use by users, in order to avoid the heat exchange medium and water mixing and affecting the user's water safety, the heat exchange medium flow channel 13a and the water flow channel 12a need to be separated from each other. By setting a portion of the sealing element 19 to seal all even-numbered flow channels 12b in the channel and another portion of the sealing element 19 to seal all odd-numbered flow channels 13b in the channel, the odd-numbered flow channels 13b and the even-numbered flow channels 12b can be isolated from each other, and the water and heat exchange medium do not affect each other, ensuring the user's drinking water (water use) safety. At the same time, the structure of the heat exchanger 100 is simpler, reducing the production difficulty of the heat exchanger 100 and improving production efficiency.

[0046] In one embodiment, the seal 19 can be welded to the heat exchange baffle 18. Welding provides very high connection strength, enabling the seal 19 to maintain structural sealing even in high-temperature environments of the heat exchange medium. It is understood that in other embodiments, the seal 19 can also be bonded to the heat exchange baffle 18. Bonding is a simpler connection method and facilitates subsequent disassembly and replacement of the seal 19.

[0047] Furthermore, this embodiment also provides a water supply device, including the heat exchanger 100 described above. By employing the heat exchanger 100, the heat exchange efficiency of the water supply device can be improved, enabling rapid output of hot or cold water.

[0048] In practical applications, the water can be heated or cooled depending on the heat exchange medium. When the heat exchange medium is a refrigerant, it can absorb heat from the water to cool it down so that the water supply device can supply cold water. When the heat exchange medium is a heat transfer medium (such as hot water), it can transfer heat to the water to heat it up so that the water supply device can supply hot water.

[0049] In this embodiment, the water supply device also includes a hot water tank, which is connected to the heat exchange medium flow channel 13a to provide a heat exchange medium (hot water) to the heat exchanger 100. Specifically, the hot water tank has an outlet and an inlet, a heat exchange medium inlet connector 40 is connected to the outlet, and a heat exchange medium outlet connector 50 is connected to the inlet, so that the heat exchange medium circulates within the hot water tank and the heat exchange medium flow channel 13a. This embodiment enables the water supply device to provide hot water by providing a hot water tank.

[0050] In one embodiment, the water supply device further includes a water circuit board connected between the heat tank and the heat exchanger 100. The water circuit board has an inlet and an outlet; the inlet connects to the outlet of the heat tank, and the outlet connects to the heat exchange medium inlet connector 40. In specific applications, the number of outlets is the same as the number of heat exchange medium inlet connectors 40, and each outlet corresponds one-to-one with the heat exchange medium inlet connector 40. In this embodiment, heat exchange medium inlet connectors 40 are respectively provided on the first side 11a and the second side 11b of the heat exchange body 10. The water circuit board spans the heat exchange body 10, and outlets are provided on both the first side 11a and the second side 11b of the heat exchange body 10.

[0051] Example 2: The main difference between the heat exchanger 100 and water supply device provided in this embodiment and those in Embodiment 1 lies in the different settings of the heat exchange medium output connector 50. Specifically, in Embodiment 1, one heat exchange medium output connector 50 is provided; while in this embodiment, at least two heat exchange medium output connectors 50 are provided.

[0052] Please see Figure 4 , Figure 6 and Figure 7Each of the first side 11a and the second side 11b is provided with at least one heat exchange medium outlet joint 50. By providing at least one heat exchange medium outlet joint 50 on each of the first side 11a and the second side 11b of the heat exchange body 10, the heat exchange medium can flow out of the heat exchange body 10 from the first side 11a and the second side 11b respectively. By setting the heat exchange medium flow channel 13a to be arranged along the first direction XX, the heat exchange medium can flow out of the heat exchange medium flow channel 13a from both sides of the arrangement direction of the heat exchange medium flow channel 13a. Compared with the technical solution where the heat exchange medium only flows out of the heat exchange medium flow channel 13a from one side of the arrangement direction of the heat exchange medium flow channel 13a, the arrangement method of this application shortens the flow path of the heat exchange medium in the far-end heat exchange medium flow channel, reduces the flow resistance, and makes the pressure distribution more balanced, thereby ensuring that the heat exchange medium in the far-end heat exchange medium flow channel can be smoothly discharged, thus ensuring that there is a sufficient amount of heat exchange medium in the far-end heat exchange medium flow channel, which is beneficial to improving the heat exchange efficiency of the heat exchanger 100.

[0053] For ease of description, the heat exchange medium output connector 50 connected to the first side 11a is defined as the first heat exchange medium output connector 51, and the heat exchange medium output connector 50 connected to the second side 11b is defined as the second heat exchange medium output connector 52.

[0054] In one embodiment, please refer to Figure 7 The heat exchange medium output channel 15 is provided with a first heat exchange medium output connector 51 and a second heat exchange medium output connector 52, both of which are connected to the heat exchange medium output channel 15. The structure is simple and easy to manufacture. In another embodiment, at least two heat exchange medium output channels 15 are provided, with the first heat exchange medium output connector 51 and the second heat exchange medium output connector 52 respectively connected to different heat exchange medium output channels 15. For example, there are two heat exchange medium output channels 15, with the first heat exchange medium output connector 51 connected to one of the heat exchange medium output channels 15 and the second heat exchange medium output connector 52 connected to the other heat exchange medium output channel 15.

[0055] Alternatively, in another embodiment, at least two heat exchange medium output channels 15 are provided, and at least one heat exchange medium output channel 15 is connected to the first heat exchange medium output connector 51 and the second heat exchange medium output connector 52. For example, two heat exchange medium output channels 15 are provided, one of which is connected to the first heat exchange medium output connector 51 and the second heat exchange medium output connector 52, and the other is connected to the first heat exchange medium output connector 51.

[0056] In one embodiment, the heat exchange medium output channel 15 connects to all heat exchange medium flow channels 13a or connects to a portion of the heat exchange medium flow channels 13a. Specifically, when there is one heat exchange medium output channel 15, it connects to all heat exchange medium flow channels 13a; when there are at least two heat exchange medium output channels 15, they can connect to all or a portion of the heat exchange medium flow channels 13a. It should be noted that when the heat exchange medium output channel 15 connects to a portion of the heat exchange medium flow channels 13a, each heat exchange medium output channel 15 is connected to a different heat exchange medium flow channel 13a, so that the heat exchange medium output connector 50 connected to all heat exchange medium output channels 15 can connect to all heat exchange medium flow channels 13a. In this embodiment, each heat exchange medium output channel 15 connects to all heat exchange medium flow channels 13a.

[0057] In one embodiment, a single heat exchange medium inlet connector 40 is provided, located on either the first side 11a or the second side 11b. In this embodiment, the heat exchange medium inlet connector 40 is located on the first side 11a. It is understood that in other embodiments, the heat exchange medium inlet connector 40 may also be configured in accordance with Embodiment 1.

[0058] Apart from the differences mentioned above, the heat exchanger 100, water supply device and its auxiliary components provided in this embodiment can be configured with reference to Embodiment 1, and will not be described here again.

[0059] Example 3: The main difference between the heat exchanger 100 and water supply device provided in this embodiment and those in embodiments one and two lies in the different settings of the water inlet connector 20. Specifically, in embodiments one and two, only one water inlet connector 20 is provided; while in this embodiment, at least two water inlet connectors 20 are provided.

[0060] Please see Figure 4 , Figure 8 and Figure 9 Each of the first side 11a and the second side 11b is provided with at least one water inlet connector 20. By providing at least one water inlet connector 20 on each of the first side 11a and the second side 11b of the heat exchange body 10, water can flow into the heat exchange body 10 from the first side 11a and the second side 11b respectively. By setting the water flow channels 12a to be arranged along the first direction XX, water can flow into the water flow channels 12a from both sides of the arrangement direction of the water flow channels 12a. Compared with the technical solution where water only flows into the water flow channels 12a from one side of the arrangement direction of the water flow channels 12a, the arrangement method of this application can make the water flow into each water flow channel 12a more evenly, thereby avoiding the situation where the amount of water in the far water flow channel 12a is small, thus helping to improve the heat exchange efficiency of the heat exchanger 100.

[0061] For ease of description, the water input connector 20 connected to the first side 11a is defined as the first water input connector 21, and the water input connector 20 connected to the second side 11b is defined as the second water input connector 22.

[0062] In one embodiment, please refer to Figure 9 The water input channel 16 is equipped with a first water input connector 21 and a second water input connector 22, both of which are connected to the water input channel 16. The structure is simple and easy to manufacture. In another embodiment, at least two water input channels 16 are provided, with the first water input connector 21 and the second water input connector 22 respectively connected to different water input channels 16. For example, there are two water input channels 16, with the first water input connector 21 connected to one of the water input channels 16 and the second water input connector 22 connected to the other water input channel 16.

[0063] Alternatively, in another embodiment, at least two water input channels 16 are provided, with at least one water input channel 16 connected to a first water input connector 21 and a second water input connector 22. For example, two water input channels 16 are provided, with one water input channel 16 connected to the first water input connector 21 and the second water input connector 22, and the other water input channel 16 connected to the first water input connector 21.

[0064] In one embodiment, the water input channel 16 connects to all water flow channels 12a or connects to a portion of the water flow channels 12a. Specifically, when there is one water input channel 16, it connects to all water flow channels 12a; when there are at least two water input channels 16, they can connect to all or a portion of the water flow channels 12a. It should be noted that when a water input channel 16 connects to a portion of the water flow channels 12a, each water input channel 16 connects to different water flow channels 12a, so that the water input connector 20 connected to all water input channels 16 can connect to all water flow channels 12a. In this embodiment, each water input channel 16 connects to all water flow channels 12a.

[0065] Apart from the differences mentioned above, the heat exchanger 100, water supply device and its auxiliary components provided in this embodiment can be configured with reference to Embodiments 1 and 2, and will not be described here.

[0066] Example 4: The main difference between the heat exchanger 100 and water supply device provided in this embodiment and those in embodiments one to three lies in the different settings of the water output connector 30. Specifically, in embodiments one to three, one water output connector 30 is provided; while in this embodiment, at least two water output connectors 30 are provided.

[0067] Please see Figure 4 , Figure 10 and Figure 11 Each of the first side 11a and the second side 11b is provided with at least one water outlet connector 30. By providing at least one water outlet connector 30 on each of the first side 11a and the second side 11b of the heat exchange body 10, water can flow out of the heat exchange body 10 from the first side 11a and the second side 11b respectively. By setting the water flow channel 12a to be arranged along the first direction XX, water can flow out of the water flow channel 12a from both sides of the arrangement direction of the water flow channel 12a. Compared with the technical solution where water only flows out of the water flow channel 12a from one side of the arrangement direction of the water flow channel 12a, the arrangement method of this application shortens the flow path of water in the far end water flow channel, reduces flow resistance, and makes the pressure distribution more balanced, thereby ensuring that the water in the far end water flow channel can be discharged smoothly, thus ensuring that there is a sufficient amount of water in the far end water flow channel, which is beneficial to improving the heat exchange efficiency of the heat exchanger 100.

[0068] For ease of description, the water output connector 30 connected to the first side 11a is defined as the first water output connector 31, and the water output connector 30 connected to the second side 11b is defined as the second water output connector 32.

[0069] In one embodiment, please refer to Figure 11 The water output channel 17 is provided with a first water output connector 31 and a second water output connector 32, both of which are connected to the water output channel 17. The structure is simple and easy to manufacture. In another embodiment, at least two water output channels 17 are provided, with the first water output connector 31 and the second water output connector 32 respectively connected to different water output channels 17. For example, there are two water output channels 17, with the first water output connector 31 connected to one of the water output channels 17 and the second water output connector 32 connected to the other water output channel 17.

[0070] Alternatively, in another embodiment, at least two water output channels 17 are provided, with at least one water output channel 17 connected to a first water output connector 31 and a second water output connector 32. For example, two water output channels 17 are provided, with one water output channel 17 connected to the first water output connector 31 and the second water output connector 32, and the other water output channel 17 connected to the first water output connector 31.

[0071] In one embodiment, the water output channel 17 connects to all water flow channels 12a or connects to a portion of the water flow channels 12a. Specifically, when there is one water output channel 17, it connects to all water flow channels 12a; when there are at least two water output channels 17, they can connect to all or a portion of the water flow channels 12a. It should be noted that when the water output channel 17 connects to a portion of the water flow channels 12a, each water output channel 17 is connected to a different water flow channel 12a, so that the water output connector 30 connected to all water output channels 17 can connect to all water flow channels 12a. In this embodiment, each water output channel 17 connects to all water flow channels 12a.

[0072] In one embodiment, a single water inlet connector 20 is provided, located on either the first side 11a or the second side 11b. In this embodiment, the water inlet connector 20 is located on the first side 11a. It is understood that in other embodiments, the water inlet connector 20 may also be configured as described in Embodiment 3.
