[0029] Embodiment 1
[0030] See also Figure 1 The utility model discloses a heat exchange component, which includes a heat exchange box 1, and the heat exchange box 1 is provided with a first cavity 11 and a second cavity 12 which are isolated from each other; specifically, a heating module 4 is provided in the first cavity 11 and / or the second cavity 12, wherein a heat exchange medium and a first heat exchange pipe 2 are provided in the first cavity 11, and both ends of the first heat exchange pipe 2 pass through the first cavity 11, and the first heat exchange pipe 2 and the heat exchange medium can exchange heat; the second cavity 12 is provided with a second heat exchange pipe 13 and a phase change material, and the phase change material is arranged on the periphery of the second heat exchange pipe 13. It should be noted that the second heat exchange pipe 13 has an open end, and the open end of the second heat exchange pipe 13 extends into the first cavity 11, and the heat exchange medium in the first cavity 11 enters the second heat exchange pipe 13 through the open end and exchanges heat with the phase change material.
[0031] On the basis of this structure, when using the heat exchange assembly of the utility model, during assembly, the second heat exchange pipe 13 can be first installed in the second cavity 12, and the phase change material can be filled to the outer periphery of the second heat exchange pipe 13, so that the outer wall of the second heat exchange pipe 13 is in contact with the phase change material. Then, the open end of the second heat exchange pipe 13 is set in the first cavity 11, and the first heat exchange pipe 2 is inserted into the first cavity 11, and the part of the first heat exchange pipe 2 inserted into the first cavity 11 is not connected with the first cavity 11 or the second cavity 12; then, a heat exchange medium is set in the first cavity 11, so that the outer periphery of the first heat exchange pipe 2 is in contact with the heat exchange medium.
[0032] The heat exchange medium may be water, pure water or oil, etc. This application takes water as the heat exchange medium for illustration.
[0033] When energy storage is needed, for example, when electricity consumption is low, heat storage can be performed first, that is, the heat exchange medium in the first cavity 11 is heated by the heating module 4, and then the heat exchange medium enters the second heat exchange pipe 13 from the open end of the second heat exchange pipe 13, and when flowing through the second cavity 12, the heat is exchanged with the phase change material through the outer wall of the second heat exchange pipe 13, so that the heat is stored in the phase change material. When the cold water of the first heat exchange pipe 2 needs to be heated, and when electricity consumption is at a peak, the heating module 4 can be turned off, and the phase change material transfers heat to the heat exchange medium in the second heat exchange pipe 13, and the heated heat exchange medium enters the first cavity 11 from the open end, and then cold water is passed into one end of the first heat exchange pipe 2, and the cold water exchanges heat with the heat exchange medium through the outer wall of the first heat exchange pipe 2, thereby heating the cold water. In this way, the phase change material can extend the water use time of the first heat exchange pipe 2 by storing heat, and can also achieve peak shifting and valley filling of electricity consumption, thereby reducing electricity costs.
[0034] Among them, the present application separates the first cavity 11 from the second cavity 12, and can separate the heat exchange medium from the phase change material. First, it can prevent the heat exchange medium from bubbling the phase change material and extend the use time of the phase change material. Secondly, it can play a decompression role; specifically, the volume of the heat exchange medium will increase when heated, thereby increasing the pressure in the cavity, and the phase change material is set in the second cavity 12 and separated from the heat exchange medium, which can reduce the pressure in a single cavity and ensure the sealing performance of the first cavity 11 and the second cavity 12. Then, by setting the open end of the second heat exchange pipe 13 in the first cavity 11, and the heat exchange medium of the first cavity 11 can enter the second cavity 12 through the second heat exchange pipe 13, heat exchange between the first cavity 11 and the second cavity 12 is achieved.
[0035] The heat exchange medium only flows and transfers heat in the heat exchange box, and very little impurities such as scale are generated, ensuring that the second heat exchange pipe 13 and the first heat exchange pipe 2 can achieve good heat exchange performance with the heat exchange medium.
[0036] It should be noted that, since the first heat exchange pipe 2 is arranged in the first cavity 11, specifically, the first heat exchange pipe 2 can be inserted into the first cavity 11 from the bottom end of the heat exchange box and pass out from the bottom end of the heat exchange box, in addition, the first heat exchange pipe 2 can also be inserted into the first cavity 11 from the bottom end of the heat exchange box and pass out from the top end of the heat exchange box; and the part of the first heat exchange pipe 2 arranged in the first cavity 11 is not connected with the first cavity 11 or the second heat exchange pipe, so when cold water is passed into the first heat exchange pipe 2, the cold water only exchanges heat with the heat exchange medium through the outer wall of the first heat exchange pipe 2 and absorbs heat, thereby heating the cold water and achieving live water washing. In this process, live water enters and exits through the first heat exchange pipe 2, and the live water does not contact the heat exchange medium of the heat exchange box 1, so it can avoid that the heated water is contaminated by scale in the heat exchange medium.
[0037] In addition, the heating module 4 can also be used to heat the phase change material or the second heat exchange pipe 13. Specifically, when the heating module 4 heats the phase change material, the phase change material stores the heat, and when it is necessary to heat the cold water, the phase change material first exchanges heat with the heat exchange medium in the second heat exchange pipe 13 to heat the heat exchange medium, and the heated heat exchange medium enters the first cavity 11 from the open end, and then the first heat exchange pipe 2 is passed with cold water, and the cold water exchanges heat with the heat exchange medium through the outer wall of the first heat exchange pipe 2, thereby heating the cold water.
[0038] When the heating module 4 heats the second heat exchange pipe 13, firstly, the second heat exchange pipe 13 exchanges heat with the phase change material and stores the heat in the phase change material, and secondly, the heat exchange medium of the second heat exchange pipe 13 flows into the first cavity 11, thereby heating the heat exchange medium in the first cavity 11, and then heating the cold water passed into the first heat exchange pipe 2; when it is necessary to heat the cold water, the phase change material first exchanges heat with the second heat exchange pipe 13 to heat the heat exchange medium in the second heat exchange pipe 13, and the heated heat exchange medium enters the first cavity 11, and then the cold water passes into the first heat exchange pipe 2, and the cold water exchanges heat with the heat exchange medium through the outer wall of the first heat exchange pipe 2, thereby heating the cold water.
[0039] It should be noted that the energy storage stage and the heating stage in the present application can also be carried out simultaneously. For example, when the heating module 4 heats the heat exchange medium in the first cavity 11, the heat exchange medium enters the second heat exchange tube 13 on the one hand to exchange heat with the phase change material to store heat in the phase change material, and on the other hand, the first heat exchange medium can also heat the first heat exchange pipe 2, so that the first heat exchange pipe 2 can realize cold water in and hot water out.
[0040] The following description is made by taking the example that the heating module 4 is disposed in the first cavity 11 and heats the first heat exchange medium:
[0041] Furthermore, both ends of the second heat exchange pipe 13 are open ends, and both open ends are arranged in the first cavity 11; specifically, the two open ends are respectively a liquid inlet end 131 and a liquid outlet end 132, wherein the heat exchange medium flows into the second heat exchange pipe 13 through the liquid inlet end 131, and flows out through the liquid outlet end 132 after heat exchange with the phase change material.
[0042] In some embodiments, in order to improve the heat exchange efficiency, a liquid pump 3 may be provided in the second heat exchange pipe 13 , and the liquid pump 3 is used to drive the heat exchange medium to flow from the liquid inlet end 131 to the liquid outlet end 132 .
[0043] When the heating module 4 is arranged in the first cavity 11, when heat storage is required, the heat exchange medium in the first cavity 11 can be heated by the heating module 4 first, and then the liquid pump 3 in the second heat exchange pipe 13 is started, so that the liquid pump 3 drives the heat exchange medium to enter the second heat exchange pipe 13 through the liquid inlet end 131 and flow to the liquid outlet end 132, and when the heat exchange medium flows through the second cavity 12, the heat is spontaneously transferred from the heat exchange medium with a higher temperature to the phase change material with a lower temperature, so that the phase change material is heated and heat is stored.
[0044] When heating cold water, when the heating module 4 is not started, the stored heat energy is used to heat the cold water, the liquid pump 3 in the second heat exchange pipe 13 is started and the heat exchange medium in the first cavity 11 enters the second heat exchange pipe 13 through the liquid inlet end 131 and flows to the liquid outlet end 132, and when the heat exchange medium flows through the second cavity 12, the heat is spontaneously transferred from the phase change material with a higher temperature to the heat exchange medium with a lower temperature, thereby heating the heat exchange medium, and the heated heat exchange medium enters the first cavity 11 from the liquid outlet end 132. Then, cold water is passed into the first heat exchange pipe 2, and the cold water exchanges heat with the heat exchange medium through the outer wall of the first heat exchange pipe 2, thereby heating the cold water.
[0045] It should be noted that the liquid inlet end 131 and the liquid outlet end 132 can be spaced apart at the two ends of the first cavity 11. In this way, during the cold water heating stage, the heated heat exchange medium is far away from the liquid inlet end 131 after coming out of the liquid outlet end 132, which can ensure that the heat exchange medium entering the second heat exchange pipe 13 through the liquid inlet end 131 is the part that has not been heated and has a lower temperature, so as to better absorb the heat of the phase change material.
[0046] Among them, since the heat exchange medium only flows in the first cavity 11 and the second heat exchange pipe 13, and does not contact or mix with external substances, it can effectively reduce the presence of impurities such as scale in the second heat exchange pipe 13 and the first cavity 11, and ensure the heat exchange efficiency. In addition, the tap water in the first heat exchange pipe 2 is not mixed with the hot water in the first cavity 11 to form warm water, but is directly heated to warm water in the first heat exchange pipe 2, which can prevent the water in the first heat exchange pipe 2 from being contaminated by the heat exchange medium of the heat exchange box 1, and achieve clean and hygienic live water washing.
[0047] Furthermore, the second heat exchange pipe 13 extends in an S-shape, and / or the second heat exchange pipe 13 includes a plurality of heat exchange pipe segments, and the plurality of heat exchange pipe segments are arranged in parallel with each other, and the two ends of the heat exchange pipe segment are respectively connected to the two open ends to increase the heat exchange area between the second heat exchange pipe 13 and the phase change material.
[0048] Specifically, the second heat exchange pipe 13 extends in an S-shaped circuitous manner to form a coil, which can extend the length of the second heat exchange pipe 13 and make full use of the internal space of the second cavity 12. The outer periphery of the second heat exchange pipe 13 is filled with a phase change material, and the heat exchange medium can exchange heat with the phase change material through the outer wall of the second heat exchange pipe 13; therefore, when the second heat exchange pipe 13 extends in an S-shaped circuitous manner, the heat exchange area of the second heat exchange pipe 13 can be increased, thereby enhancing the heat exchange effect between the heat exchange medium and the phase change material. At the same time, the time for the heat exchange medium to flow through the second cavity 12 is extended, and it can fully exchange heat with the phase change material, thereby improving the heat exchange efficiency.
[0049] In addition, the second heat exchange pipe 13 can also be a segmented pipe segment, specifically, it includes multiple heat exchange pipe segments, and each heat exchange pipe segment can be a straight pipe segment and / or a curved pipe segment, and the two ends of the heat exchange pipe segment are respectively a first end and a second end; when assembled, the first end of each heat exchange pipe segment is connected by a connecting pipe segment, and the second end of each heat exchange pipe segment is connected by another connecting pipe segment, and the two connecting pipe segments are respectively connected to the two open ends. When in use, the heat exchange medium in the first cavity 11 enters the connecting pipe segment from an open end of the second heat exchange pipe 13, and the heat exchange medium entering the connecting pipe segment is divided into multiple streams and flows into different heat exchange pipe segments, and after being collected in another connecting pipe segment, it enters the first cavity 11 through another open end of the second heat exchange pipe 13. In this way, since the heat exchange medium is diverted to different heat exchange pipe segments for heat exchange, multiple heat exchange pipe segments accumulate to form a larger heat exchange outer surface, which can accelerate the heat exchange efficiency.
[0050] Furthermore, a heating module 4 is provided in the first cavity 11 , and the heating module 4 is used to heat the heat exchange medium.
[0051] Among them, the heating module 4 is used to heat the heat exchange medium and realize heat transfer through heat exchange between the heat exchange medium and the phase change material; compared with setting the heating module 4 in the second cavity 12, when the heating module 4 is set in the first cavity 11, when the phase change material in the second cavity 12 undergoes phase change due to temperature change, it will not affect the heating module 4 in the first cavity 11, thereby reducing the possibility of damage to the heating module 4 and improving the reliability of use.
[0052] Furthermore, two ends of the first heat exchange pipe 2 are a water inlet 21 and a water outlet 22 , wherein the water inlet 21 is used for cold water to flow in, and the water outlet 22 is used for hot water to flow out after heat exchange.
[0053] Based on this structure, when in use, tap water flows into the first heat exchange pipe 2 through the water inlet end 21, and exchanges heat with the hot water in the first cavity 11 through the part of the first heat exchange pipe 2 located in the first cavity 11, so that the cold water is heated into hot water in the first heat exchange pipe 2 and then flows out from the water outlet end 22.
[0054] Since the portion of the first heat exchange pipe 2 passing through the first cavity 11 is not connected to the first cavity 11 or the second heat exchange pipe, when cold water is passed into the first heat exchange pipe 2, the cold water only exchanges heat with the heat exchange medium through the outer wall of the first heat exchange pipe 2 and absorbs heat, thereby heating the cold water and realizing the instant heating function. In this process, live water enters and exits through the first heat exchange pipe 2, and the live water does not contact the inner tank of the heat exchange box 1 or the second heat exchange pipe 13, realizing clean and hygienic live water washing.
[0055] Furthermore, the outer surface of the first heat exchange pipe 2 is a non-flat surface, and / or the first heat exchange pipe 2 includes multiple heating pipe segments, and both ends of the multiple heating pipe segments are respectively connected to the water inlet end 21 and the water outlet end 22; wherein the non-flat surface and / or multiple heating pipe segments are used to increase the heat exchange area between the first heat exchange pipe 2 and the heat exchange medium.
[0056] Specifically, a plurality of heat exchange fins 23 may be provided on the outer surface of the first heat exchange pipe 2 to increase the heat exchange area between the first heat exchange pipe 2 and the heat exchange medium; since the first heat exchange pipe 2 exchanges heat with the heat exchange medium through the outer surface, the larger the outer surface area of the first heat exchange pipe 2, the larger the contact area between the first heat exchange pipe 2 and the heat exchange medium, and the better the heat exchange effect. In this embodiment, a plurality of heat exchange fins 23 are added to the outer periphery of the first heat exchange pipe 2 to increase the heat exchange area between the first heat exchange pipe 2 and the heat exchange medium, so that the tap water in the first heat exchange pipe 2 absorbs as much heat from the heat exchange medium as possible during the distance from the water inlet end 21 to the water outlet end 22, thereby being heated to the required temperature.
[0057] In addition, the first heat exchange pipe 2 can also be configured to be connected to multiple heating pipe segments. Specifically, the first heat exchange pipe 2 includes multiple heating pipe segments, and each heating pipe segment can be a straight pipe segment and / or a curved pipe segment, and the two ends of the heating pipe segment are respectively the third end and the fourth end; during assembly, the third end of each heating pipe segment is connected through a connecting pipe segment, and the fourth end of each heating pipe segment is connected through another connecting pipe segment, and the two connecting pipe segments are respectively connected to the water inlet end 21 and the water outlet end 22.
[0058] When in use, cold water in the external water circuit enters the connecting pipe section through the water inlet end 21 of the first heat exchange pipe 2. The cold water entering the connecting pipe section is divided into multiple streams and flows into different heating pipe sections. Heat exchange is performed with the heat exchange medium in the first cavity 11 through the heating pipe section. The heated warm water is collected in another connecting pipe section and then flows out through the water outlet end 22 of the first heat exchange pipe 2.
[0059] In this way, since the cold water is diverted to different heating pipe sections for heating, the multiple heating pipe sections accumulate to form a larger heat exchange outer surface area, which can increase the heating efficiency.
[0060] In other embodiments, the portion of the first heat exchange pipe 2 disposed inside the heat exchange box 1 may be extended in a spiral shape to increase the heat exchange area between the first heat exchange pipe 2 and the heat exchange medium.
[0061] The first heat exchange pipe 2 is extended in a spiral shape to increase the outer surface of the first heat exchange pipe 2, thereby increasing the heat exchange area between the first heat exchange pipe 2 and the heat exchange medium, thereby improving the heat exchange efficiency. In addition, after the first heat exchange pipe 2 is extended in a spiral shape, the length of the first heat exchange pipe 2 is extended, and the cold water stays in the first cavity 11 for a longer time after entering the spiral section, and can be in contact with the heat exchange medium for a longer time, thereby obtaining more heat and improving the heating effect.
[0062] Furthermore, the first cavity 11 is a transparent cavity.
[0063] Specifically, the portion of the shell of the heat exchange box 1 corresponding to the first cavity 11 can be set as a transparent shell, so that the first cavity 11 is a transparent cavity. At the same time, the portion of the first heat exchange pipe 2 located in the first cavity 11 can also be set as a transparent pipe section; in this way, visualization of live water washing can be achieved, that is, the user can intuitively see that the tap water in the first heat exchange pipe 2 does not need to be mixed with the hot water in the first cavity 11 to be used as warm water, but the tap water is directly heated to warm water by heat exchange, so that live flowing pure tap warm water can be used.
[0064] It should be noted that in this embodiment, the first cavity 11 is separated from the second cavity 12 to separate the heat exchange medium from the phase change material, thereby facilitating the first cavity 11 to be set as a transparent cavity so that the water flow in the first cavity 11 can be intuitively seen.
[0065] Further, the position of the first cavity 11 directly facing the first heat exchange pipe 2 is a transparent cavity, and / or the portion of the first heat exchange pipe 2 disposed in the first cavity 11 is a transparent pipe section.
[0066] Specifically, the shell part that needs to be set to be transparent can be made of transparent materials such as transparent glass or plastic to visualize the first cavity 11. In this embodiment, only the part of the first cavity 11 corresponding to the first heat exchange pipe 2 is set as a transparent area, and the user can visually see the water flow in the first heat exchange pipe 2 from the outside. At the same time, the use of transparent materials is reduced to ensure the heat preservation effect of the heat exchange box 1.
[0067] In addition, when the portion of the first heat exchange pipe 2 disposed in the first cavity 11 is a transparent pipe section, the water flow and heat exchange conditions in the first heat exchange pipe 2 can be more intuitively seen.
[0068] Furthermore, the heat exchange box 1 comprises an outer shell and an inner shell, and the inner shell is provided with the first cavity 11 and the second cavity 12. A heat preservation structure is provided between the outer shell and the inner shell.
[0069] The heat exchange box 1 is further divided into a first cavity 11 and a second cavity 12 by a partition wall 14 , and a heat preservation structure is also provided in the partition wall 14 .
[0070] Specifically, the thermal insulation structure may be a polyurethane foam layer, a polystyrene board or a glass fiber board, etc., which has good thermal insulation and heat insulating properties, can ensure the thermal insulation performance of the heat exchange box 1 and reduce heat loss.
[0071] In addition, the heating module 4 in this embodiment can be a heating rod, a heating tube, etc.
[0072] Embodiment 2
[0073] Different from the first embodiment, this embodiment discloses an energy storage water heater, which includes the heat exchange component of the first embodiment. The specific structure and use principle of the heat exchange component are explained in the first embodiment and will not be described in detail here.
[0074] It should be noted that the energy storage water heater in this embodiment can achieve the instant heating function by adopting the above-mentioned heat exchange component, and the phase change material is used for heat storage, which can extend the water use time of the first heat exchange pipe 2, and can also realize the peak shifting and valley filling of electricity consumption, thereby reducing the electricity cost. Among them, the tap water of the water pipe only flows in and out of the first heat exchange pipe 2, and is not mixed with the hot water in the second heat exchange pipe 13 for heat exchange, which can prevent the cold water in the first heat exchange pipe 2 from being contaminated by scale after being heated; the heat exchange medium and the phase change material are separated by two cavities, which can reduce the pressure of the water heater when storing heat or heating cold water, and avoid damage to the heat exchange box 1; at the same time, the heat exchange medium in the heat exchange component only flows in the second heat exchange pipe 13 and the first cavity 11, which can reduce the generation of scale in the inner tank of the heat exchange box 1.
[0075] In addition, the present application separates the first cavity 11 from the second cavity 12, which can separate the heat exchange medium from the phase change material, prevent the heat exchange medium from bubbling the phase change material, and extend the use time of the phase change material. Secondly, it can play a decompression role; specifically, when the heat exchange medium is heated, the volume will increase, thereby increasing the pressure in the cavity, and the phase change material is set in the second cavity 12 to separate from the heat exchange medium, which can reduce the pressure in a single cavity and ensure the sealing performance of the first cavity 11 and the second cavity 12. At the same time, it is also convenient to set the part of the heat exchange box 1 corresponding to the first cavity 11 as a visual cavity, and the part of the first heat exchange pipe 2 set in the heat exchange box 1 is set as a visual pipe section. The user can directly see that the tap water in the water pipe does not need to be mixed with the hot water in the insulation tank to be used as warm water, but directly heat exchange to obtain hot water, thereby realizing clean and hygienic visual live water washing.
[0076] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features.
