[0029] Referring to Figure 1 The utility model embodiment provides a water supply device, including heat exchange structure and hot tank, heat exchange structure includes water flow channel 11 and heat exchange medium channel 12 that isolate each other, water flow channel 11 and heat exchange medium channel 12 heat conduction connection, hot tank and heat exchange medium channel 12 communicate.

[0030] In practical application, hot tank inside is equipped with heat exchange medium, water flow channel 11 is connected with inlet pipe and outlet pipe respectively, and water flows into water flow channel 11 from inlet pipe, and flows out from outlet pipe after water flow channel 11, to supply user to use, hot tank and heat exchange medium channel 12 are connected, and hot water (heat exchange medium) in hot tank flows to heat exchange medium channel 12, and when hot water (heat exchange medium) flows in heat exchange medium channel 12, because heat exchange medium channel 12 and water flow channel 11 are heat conduction connection, hot water (heat exchange medium) and water in water flow channel 11 can exchange heat, to heat the water of water flow channel 11.

[0031] It needs to be explained that the water supply device further includes a pump body and a heating element, the pump body is connected with the hot tank, and the pump body is used to drive the hot water (heat exchange medium) to circulate and flow in the hot tank and the heat exchange medium channel 12; the heating element is connected with the hot tank, and the heating element is used to heat the hot water (heat exchange medium) in the hot tank, so that the hot water (heat exchange medium) is kept at a specific temperature, thereby facilitating heating of the water flow in the water flow channel 11.

[0032] Referring to Figure 1 And Figure 2 The heat exchange structure includes a plurality of heat-conducting plates 1 and a pressing structure 4, the plurality of heat-conducting plates 1 are arranged in sequence along the height direction of the heat exchange structure, and water flow channels 11 or heat exchange medium channels 12 are formed between adjacent heat-conducting plates 1; the outer edges 14 of the plurality of heat-conducting plates 1 are overlapped together, and the pressing structure 4 is used to press the outer edges 14 of the plurality of heat-conducting plates 1.

[0033] In order to clearly describe the examples, Figure 2 In the examples, the X direction represents the height direction of the heat exchanger body. In practical application, the plurality of heat-conducting plates 1 are arranged in sequence along the height direction, and water flow channels 11 or heat exchange medium channels 12 are formed between adjacent two heat-conducting plates 1; the water flow channels 11 and the heat exchange medium channels 12 formed in this way have relatively large cross-sectional areas in the horizontal plane, and the cross-sectional areas of the water flow channels 11 and the heat exchange medium channels 12 usually serve as heat-conducting surfaces, so that the heat-conducting area of the water flow channels 11 and the heat exchange medium channels 12 in contact with each other is increased, and the heat-conducting efficiency is improved.

[0034] The water flow channel 11 and the heat exchange medium channel 12 are isolated from each other and in thermal conduction connection, the water flow channel 11 is for water flow to pass through, the heat exchange medium channel 12 is for heat exchange medium to pass through, the heat exchange medium channel 12 and the water flow channel 11 are in thermal conduction connection, so as to facilitate heat exchange between the heat exchange medium and the water flow, and the effect of heating the water flow is achieved.

[0035] Meanwhile, the application also comprises a pressing structure 4, the pressing structure 4 presses the edge portions of the plurality of heat conduction plates 1 together, so as to realize the effect of sealed connection of the edge portions of the plurality of heat conduction plates 1, and avoid the water flow in the water flow channel 11 or the heat exchange medium in the heat exchange medium channel 12 from penetrating to the outside, polluting the environment of the water supply device and causing water waste.

[0036] Compared with the prior art, the heat exchange structure of the application adopts the form that the plurality of heat conduction plates 1 are arranged in sequence along the height direction, so that the cross-sectional area of the water flow channel 11 and the heat exchange medium channel 12 formed is larger, the heat conduction area of the water flow channel 11 and the heat exchange medium channel 12 is increased, and the heat conduction efficiency is improved, meanwhile, the plurality of heat conduction plates 1 are arranged in sequence along the height direction, so that the length of the water flow channel 11 and the heat exchange medium channel 12 along the height direction is smaller, the flow per unit area of the water flow in the water flow channel 11 is smaller, and the water flow can quickly absorb the heat of the heat exchange medium, the efficiency of heat exchange is improved, the water heating time is saved, the effect of hot water immediately is realized. And the plurality of heat conduction plates 1 are sealed and fixed by the pressing structure 4, the pressing structure 4 enhances the mechanical strength of the edge portions of the heat conduction plates 1, improves the anti-external force and anti-deformation ability, and ensures the stability in the use process; meanwhile, the connection mode is simpler, the production and assembly speed can be accelerated, and the production cost is reduced.

[0037] In an embodiment, the water flow channel 11 and the heat exchange medium channel 12 are arranged in sequence and alternately.

[0038] Specifically, the plurality of heat conduction plates 1 are arranged in sequence along the height direction, the water flow channel 11 and the heat exchange medium channel 12 are alternately formed between the adjacent two heat conduction plates 1, or the water flow channel 11 is formed between the adjacent two heat conduction plates 1, and the heat exchange medium channel 12 is formed in the heat conduction plate 1 itself, so that the effect of the water flow channel 11 and the heat exchange medium channel 12 arranged in sequence and alternately can also be achieved. The water flow channel 11 and the heat exchange medium channel 12 are arranged in sequence and alternately, so that one water flow channel 11 is clamped between two heat exchange medium channels 12, and the water flow channel 11 is simultaneously subjected to heat conduction by the heat exchange medium channels 12 on both sides, which greatly shortens the water heating time and improves the efficiency of hot water.

[0039] Again refer to Figure 2 and Figure 3, the heat-conducting plate 1 comprises a main body part 13 and an outer edge 14 connected to the outer periphery of the main body part 13, and the main body parts 13 of the plurality of heat-conducting plates 1 are arranged at intervals to form the water flow channel 11 or the heat exchange medium channel 12; the outer edge 14 extends in the horizontal direction, and the pressing structure 4 is used to press the plurality of outer edges 14 tightly.

[0040] In actual application, the plurality of main body parts 13 are arranged at intervals to form the water flow channel 11 or the heat exchange medium channel 12, the main body part 13 mainly serves as the heat-conducting surface of the water flow channel 11 and the heat exchange medium channel 12, and the outer edge 14 mainly serves as the connecting part of the two heat-conducting plates 1. The outer edge 14 is arranged at the outer periphery of the main body part 13 to facilitate the assembly work of the operator, and the pressing structure 4 is used to press the plurality of outer edges 14 tightly to make the contact between the adjacent two heat-conducting plates 1 more closely, thereby reducing the contact thermal resistance and improving the heat transfer efficiency. At the same time, the heat-conducting plate 1 and the pressing structure 4 form a more solid whole, which can withstand greater mechanical stress without being easily deformed or broken.

[0041] Referring to Figure 4 , the outer edge 14 comprises a horizontal part 141 and a vertical part 142 connected to each other, the horizontal part 141 is connected to the main body part 13, and the vertical part 142 is connected to the side of the horizontal part 141 away from the main body part 13. The pressing structure 4 is used to press the plurality of vertical parts 142 tightly, or the pressing structure 4 is used to press the plurality of vertical parts 142 and the plurality of horizontal parts 141 tightly.

[0042] In actual application, the outer edge 14 comprises the horizontal part 141 and the vertical part 142, the horizontal part 141 is connected to the main body part 13, the horizontal part 141 extends in the horizontal direction, and the vertical part 142 extends in the vertical direction. When the plurality of heat-conducting plates 1 are stacked together, the plurality of horizontal parts 141 are stacked together, and the plurality of vertical parts 142 are stacked together. The pressing structure 4 can press the plurality of vertical parts 142 tightly to make the connection of the plurality of vertical parts 142 more closely and form a sealed connection. In this way, the structure and shape of the vertical part 142 itself play a limiting role to prevent the water flow or the heat exchange medium from seeping out to the outside. The pressing structure 4 is pressed tightly to the plurality of vertical parts 142 to further strengthen the stable connection between the plurality of vertical parts 142, reduce the contact thermal resistance, and improve the heat transfer efficiency.

[0043] The pressing structure 4 can also press the plurality of vertical parts 142 and the plurality of horizontal parts 141 tightly at the same time. In this way, the connection of the plurality of heat-conducting plates 1 is more stable and more closely, thereby making the thermal resistance between the water flow channel 11 and the heat exchange medium channel 12 smaller and improving the heat exchange efficiency of the water flow channel 11 and the heat exchange medium channel 12.

[0044] Referring again to Figure 5The pressing structure 4 comprises an upper clamping plate 41, a lower clamping plate 42 and fasteners, the outer edges 14 of the plurality of heat-conducting plates 1 are overlapped together and located between the upper clamping plate 41 and the lower clamping plate 42, and the fasteners are used to lock the upper clamping plate 41 and the lower clamping plate 42 together along the height direction.

[0045] In actual application, taking the example of pressing the plurality of horizontal parts 141 together by the pressing structure 4, along the height direction, the upper clamping plate 41 is overlapped on the topmost horizontal part 141, and the lower clamping plate 42 is placed below the bottommost horizontal part 141, the upper clamping plate 41 and the lower clamping plate 42 are locked together along the height direction, the upper clamping plate 41 and the lower clamping plate 42 have a clamping force therebetween, the clamping force tightly presses the plurality of horizontal parts 141 together, meanwhile, the upper clamping plate 41, the lower clamping plate 42 and the heat-conducting plates 1 form an integral structure, the integral structure has greater structural stability and can withstand greater vibration and mechanical force, thereby improving the rigidity of the heat exchange structure itself.

[0046] Referring again to Figure 5 The upper clamping plate 41 has a first connecting part 411, a first clamping part 412 and a second connecting part 413 in sequence along the length direction thereof, the lower clamping plate 42 has a third connecting part 421, a second clamping part 422 and a fourth connecting part 423 in sequence along the length direction thereof, the plurality of outer edges 14 are located between the first clamping part 412 and the second clamping part 422, the first connecting part 411 and the third connecting part 421 are oppositely arranged and locked by fasteners, and the second connecting part 413 and the fourth connecting part 423 are oppositely arranged and locked by fasteners.

[0047] In actual application, the first clamping part 412 and the second clamping part 422 can be provided with limiting grooves, and the outer edges 14 are located in the limiting grooves, so that the positioning of the outer edges 14 can be quickly realized during pressing, the pressing efficiency is improved, the outer edges 14 are limited, and the movement of the outer edges 14 is prevented, so as to affect the pressing effect; the first connecting part 411 and the third connecting part 421 are oppositely arranged along the height direction and are pulled tight by fasteners, and the second connecting part 413 and the fourth connecting part 423 are oppositely arranged along the height direction and are pulled tight by fasteners, so that the opposite sides of the upper clamping plate 41 and the lower clamping plate 42 are locked by fasteners, the uniform distribution of the pressing force on the entire contact surface can be ensured, the uneven pressing force caused by unilateral locking is avoided, the local stress concentration is reduced, and material deformation or damage is prevented; uniform and firm locking can reduce the gap between the adjacent two heat-conducting plates 1, reduce the contact thermal resistance and improve the heat exchange efficiency.

[0048] Referring again to Figure 5 and Figure 6The locking member 43 is an elastic member or a bolt. If the bolt is used to lock the upper clamping plate 41 and the lower clamping plate 42, the bolt locking allows the operator to accurately adjust the locking force according to the needs, to ensure the best contact pressure. Once tightened correctly, the bolt connection is usually very stable and not easy to loosen, especially suitable for static or low-vibration environments. The bolt connection is convenient to disassemble and reinstall, which is convenient for maintenance, inspection or replacement of components; this helps to reduce maintenance costs and time.

[0049] If the elastic member is used to tension the upper clamping plate 41 and the lower clamping plate 42, the elastic member locking can automatically compensate for size changes caused by temperature changes, material creep or wear to some extent, maintaining constant contact pressure. In a vibration or impact environment, the elastic member can absorb part of the energy, reducing the impact on the connection point and prolonging the service life. The elastic member locking usually does not require complex tools or steps and can be quickly installed to improve production efficiency. The elastic member can be a spring structure, for example.

[0050] It should be noted that in other embodiments, the pressure structure 4 can also use other ways, which are not limited in this application.

[0051] Again refer to Figure 2 The adjacent two heat exchange partitions form a flow channel 15. Along the height direction, a plurality of heat exchange partitions form a plurality of layers of flow channels 15. The plurality of layers of flow channels 15 are sequentially divided into odd layers of flow channels 151 and even layers of flow channels 152 along the height direction. The plurality of odd layers of flow channels 151 are in communication with each other, and the plurality of even layers of flow channels 152 are in communication with each other. The odd layers of flow channels 151 and the even layers of flow channels 152 are isolated from each other. The odd layers of flow channels 151 are one of the water flow channels 11 and the heat exchange medium channels 12, and the even layers of flow channels 152 are the other one of the water flow channels 11 and the heat exchange medium channels 12. The heat exchanger is provided with a first flow guide channel 161 and a second flow guide channel 171 penetrating each flow channel 15. The heat exchanger includes a sealing member 2. The sealing member 2 is used to seal all odd layers of flow channels 151 in the first flow guide channel 161. The sealing member 2 is used to seal all even layers of flow channels 152 in the second flow guide channel 171.

[0052] In actual application, a plurality of heat conduction plates 1 form a plurality of layers of flow channels 15 along the height direction. The plurality of layers of flow channels 15 are further divided into odd layers of flow channels 151 and even layers of flow channels 152 along the height direction. The odd layers of flow channels 151 are, for example, the first layer, the third layer, etc. The even layers of flow channels 152 are, for example, the second layer, the fourth layer, etc. The odd layers of flow channels 151 can be the heat exchange medium channels 12, and the even layers of flow channels 152 can be the water flow channels 11. In this way, the opposite sides of each layer of water flow channels 11 are heated by the heat exchange medium channels 12 on both sides, effectively saving the heating time of the water flow in the water flow channels 11 and improving the hot water output speed of the water supply device.

[0053] And, since the heat exchange medium is mainly used for heating the water flow, and the water flow is required to flow out of the water supply device for direct use by the user, in order to avoid the heat exchange medium and the water flow from mixing together and affecting the user's water safety, the heat exchange medium channel 12 and the water flow channel 11 need to be spaced apart from each other. In an embodiment, the heat exchange structure is provided with a first flow guide channel 161 and a second flow guide channel 171 penetrating each heat conduction plate 1. If the first flow guide channel 161 is connected with an external water source (or water inlet pipeline), the first flow guide channel 161 is a channel for the water flow to enter, so the odd-numbered layer flow passages 151 in the first flow guide channel 161 need to be sealed, allowing only the water flow to enter the even-numbered layer flow passages 152 from the first flow guide channel 161; if the second flow guide channel 171 is connected with the heat tank, the second flow guide channel 171 is a channel for the heat exchange medium to enter, so the even-numbered layer flow passages 152 in the second flow guide channel 171 need to be sealed, allowing only the heat exchange medium to enter the odd-numbered layer flow passages 151 from the second flow guide channel 171.

[0054] In this way, the odd-numbered layer flow passages 151 and the even-numbered layer flow passages 152 can be isolated from each other, the water flow and the heat exchange medium do not affect each other, ensuring the safety of the user's drinking water (water use), and at the same time, the structure of the heat exchange structure is simpler, reducing the production difficulty of the heat exchange structure and improving the production efficiency.

[0055] Referring again to Figure 2 , the heat exchange structure includes a first group of interfaces 16 and a second group of interfaces 17, the first group of interfaces 16 is connected with the water flow channel 11, and the second group of interfaces 17 is connected with the heat exchange medium channel 12. Specifically, the first group of interfaces 16 includes a first water inlet and a first water outlet, the first water inlet is respectively connected with the water inlet pipeline and the water flow channel 11, and the first water outlet is respectively connected with the water flow channel 11 and the water outlet pipeline. The water flow enters the water flow channel 11 from the first water inlet, is heated by the heat exchange medium, and then flows to the water outlet pipeline from the first water outlet, and flows out of the water outlet pipeline for the user to use. The second group of interfaces 17 includes a second water inlet and a second water outlet, the second water inlet is respectively connected with the heat tank and the heat exchange medium channel 12, and the second water outlet is respectively connected with the heat tank and the heat exchange medium channel 12. The heat exchange medium in the heat tank enters the heat exchange medium channel 12 from the second water inlet, exchanges heat with the water flow in the heat exchange medium channel 12, and then flows back to the heat tank from the second water outlet for heating, so as to facilitate the next heat exchange.

[0056] Referring to Figure 7 , the heat conduction plate 1 is provided with a plurality of barrier ribs 3 along the length direction thereof. In actual application, the heat conduction plate 1 is provided with a plurality of barrier ribs 3, the plurality of barrier ribs 3 increases the surface area of the heat conduction plate 1, thereby providing more heat transfer surfaces, and a larger heat exchange area means a higher heat transfer efficiency; the barrier ribs 3 increase the resistance of the fluid flowing in the flow passage 15, prolong the heat exchange time of the water flow and the heat exchange medium, and thereby improve the heat exchange efficiency.

[0057] In an embodiment, the barrier ribs 3 include first ribs 31 and second ribs 32, which are arranged in a V shape. The V-shaped flow channel 15 changes the flow direction of the fluid, so that more turbulent flow is generated when the fluid flows through the V-shaped groove. The turbulent flow can increase the heat exchange efficiency between the fluid and the wall, thereby improving the overall heat exchange performance.

[0058] In an embodiment, the barrier ribs 3 are wavy, and the shape of the wavy flow channel 15 increases the actual contact area between the fluid and the wall, provides more heat exchange opportunities, and improves the heat exchange capacity per unit volume.

[0059] In addition, the opening directions of the V-shaped barrier ribs 3 on the adjacent two heat-conducting plates 1 are opposite.

[0060] In actual application, the flow directions in the adjacent water flow channels 11 and heat exchange medium channels 12 can be opposite, so that the water flow and the heat exchange medium form counter-flow directions, thereby prolonging the heating time; in the corresponding water flow channels 11 and heat exchange medium channels 12, the V-shaped barrier ribs 3 are generally the same as the flow directions of the water flow or the heat exchange medium, so as to guide the water flow and the heat exchange medium to flow more smoothly. Therefore, since the flow directions in the water flow channels 11 and the heat exchange medium channels 12 are opposite, the opening directions of the V-shaped barrier ribs 3 on the adjacent two heat-conducting plates 1 are opposite, thereby prolonging the heat exchange time of the water flow and the heat exchange medium to a certain extent while guiding the water flow and the heat exchange medium.

[0061] Compared with the prior art, the heat exchange structure of the present application adopts the form that the plurality of heat-conducting plates 1 are arranged in sequence along the height direction, so that the cross-sectional areas of the water flow channels 11 and the heat exchange medium channels 12 formed are large, the heat conduction areas of the water flow channels 11 and the heat exchange medium channels 12 are increased, and the heat conduction efficiency is improved. At the same time, the plurality of heat-conducting plates 1 are arranged in sequence along the height direction, so that the lengths of the water flow channels 11 and the heat exchange medium channels 12 along the height direction are small, the flow rate per unit area of the water flow in the water flow channels 11 is small, the water flow can quickly absorb the heat of the heat exchange medium, the heat exchange efficiency is improved, the water flow heating time is saved, and the effect of hot water immediately is achieved. In addition, the plurality of heat-conducting plates 1 are sealed and fixed by the pressing structure 4, the pressing structure 4 enhances the mechanical strength of the edge portions of the heat-conducting plates 1, improves the anti-external force and anti-deformation abilities thereof, and ensures the stability in use. At the same time, the connection mode is simpler, the production and assembly speed can be accelerated, and the production cost is reduced.
