[0040] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the present invention.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0041] With the country's vigorous promotion of a green, low-carbon, and circular economy, coal-fired heating is gradually shifting to electric heating. Currently, electricity prices peak during the day and trough at night. To save electricity and reduce heating costs, more and more heaters are adopting heat storage heaters, which store heat energy during the night when electricity prices are low and release it during the day when electricity prices are high. Current phase change heat exchangers can only exchange heat and cannot store energy, resulting in significant limitations for phase change heat exchange equipment.
[0042] It should be specifically noted that the first direction referred to in this utility model is as follows: Figure 6 or Figure 7 The direction shown is from top to bottom.
[0043] Therefore, this embodiment provides a phase change heat exchange device 100. The phase change heat exchange device 100 can perform energy storage or heat exchange.
[0044] Please see Figure 1 A phase change heat exchange device 100 includes: a phase change energy storage component 10, a shell 20, a heat collector 30, a heat conductor 40, a heat release component 50, and an energy replenishment component 60.
[0045] The heat collector 30 is disposed inside the housing 20, and the heat collector 30 has a heat collection section 31, which is provided with a phase change energy storage device 10; one end of the heat conductor 40 is connected to the heat collector 30, and the other end of the heat conductor 40 is connected to the heat release component 50; the heat release component 50 is disposed outside the housing 20; the energy replenishment component 60 is in communication with the housing 20;
[0046] The energy storage component is used to provide energy to the phase change energy storage component 10, and the heat collection component 30 is used to absorb the heat released by the phase change energy storage component 10 and transfer it to the heat release component 50 through the heat conduction component 40.
[0047] The aforementioned phase change heat exchanger 100 has a heat collector 30 installed in the housing 20, and a heat collection section 31 installed on the heat collector 30. By installing a phase change energy storage device 10 on the heat collection section 31, after the phase change energy storage device 10 releases heat, the heat collector 30 absorbs the heat from the phase change energy storage device 10 and then conducts the heat to the heat release component 50 through the heat conduction component 40. The heat release component 50 releases heat to realize the use of the energy of the phase change energy storage device 10. The energy replenishment component 60 is connected to the housing 20, so the energy replenishment component 60 can provide energy to the phase change energy storage device 10.
[0048] Understandably, a heat collector 30 is provided inside the aforementioned housing 20, and a heat collection section 31 is provided on the heat collector 30. By placing the phase change energy storage device 10 on the heat collection section 31, the heat of the phase change energy storage device 10 can be collected through the heat collection section 31. The heat collected by the heat collection section 31 can then be conducted to the heat release component 50 through the heat conduction component 40. In this way, the heat release component 50 can release the heat absorbed by the heat collector 30 and heat the airflow near the heat release component 50, thus realizing the application of the energy in the aforementioned phase change energy storage device 10.
[0049] Understandably, an energy replenishment component 60 is also provided outside the housing 20. The energy replenishment component 60 is connected to the housing 20 and is used to replenish the energy of the phase change energy storage device 10 inside the housing 20. Specifically, when the phase change energy storage device 10 stops working, the energy replenishment component 60 can absorb energy from outside the housing 20, and the energy is input into the housing 20 through the energy replenishment component 60, so that the phase change energy storage device 10 can absorb the heat from the energy replenishment component 60.
[0050] Please see Figure 2 In some embodiments, the energy replenishment component 60 includes: a heat source 61 and a heat transfer element 62;
[0051] The heat source 61 is disposed outside the housing 20, the heat source 61 is connected to the heat transfer element 62, and the heat transfer element 62 is connected to the phase change energy storage element 10.
[0052] Understandably, the aforementioned energy replenishment component 60 includes a heat source 61 and a heat transfer element 62. The heat source 61 is located outside the housing 20. The heat source 61 heats the heat transfer element 62 to transfer heat to the housing 20, thereby heating the airflow inside the housing 20 and raising the temperature inside the housing 20. After the temperature inside the housing 20 rises, the phase change energy storage component 10 can absorb the temperature of the housing 20 to store energy. This enables the phase change energy storage component 10 inside the housing 20 to store energy. After storing energy, the phase change energy storage component 10 can release heat to the heat collector 30. This allows the phase change heat exchange device 100 to store energy and release heat, so that the phase change heat exchange device 100 can simultaneously achieve energy storage and heat exchange.
[0053] Please see Figure 3 and Figure 4 In some embodiments, the heat dissipation component 50 includes: a driving component 51 and a heat dissipation component 52;
[0054] The heat sink 52 is connected to the heat conductor 40. The heat sink 52 is provided with a recess 521, and the driving member 51 is disposed in the recess 521.
[0055] Understandably, the heat dissipation component 50 includes a driving component 51 and a heat dissipation component 52. The heat dissipation component 52 is connected to the heat conduction component 40, so that the heat from the heat collection component 30 can be transferred to the heat dissipation component 52 through the heat conduction component 40, giving the heat dissipation component 52 a certain temperature. In order to dissipate heat better, a recess 521 is provided on the heat dissipation component 52. By setting the driving component 51 in the recess 521, the driving component 51 drives the airflow near the heat dissipation component 52 to circulate, so that the airflow near the heat dissipation component 52 can flow, thereby allowing the airflow near the heat dissipation component 52 to be heated by the heat dissipation component 52 more quickly. At the same time, it can also make the temperature of the heat dissipation component 52 drop as quickly as possible, so that the heat from the heat conduction component 40 can be transferred to the heat dissipation component 52 more quickly, thereby achieving the purpose of accelerating the heat exchange efficiency of the phase change heat exchange device 100.
[0056] Please see Figure 3 and Figure 5 In some embodiments, the heat dissipation assembly 50 further includes a housing 70;
[0057] The driving component 51 and the heat dissipation component 52 are both disposed inside the housing 70. The housing 70 has an air inlet 71 and an air outlet 72 on opposite sides. The driving component 51 is used to drive airflow into the housing 70 from the air inlet 71 and blow it out from the air outlet 72.
[0058] Understandably, the heat dissipation component 50 also includes a housing 70, within which a drive component 51 and a heat dissipation component 52 are installed. Placing the heat dissipation component 52 and the drive component 51 within the housing 70 can accelerate the heating efficiency of the airflow. Furthermore, an air inlet 71 and an air outlet 72 are respectively provided on opposite sides of the housing 70. The air inlet 71 allows airflow to enter the housing 70, and the drive component 51 can accelerate the flow rate of the airflow entering the housing 70. At the same time, the drive component 51 can also discharge the airflow from the housing 70, thus accelerating the airflow and increasing the airflow speed, thereby improving the heat dissipation efficiency of the heat dissipation component 52.
[0059] Understandably, the air inlet 71 provided on the aforementioned housing 70 allows for a greater flow rate of air entering than the air outlet 72 allows for air outflow. This ensures that the airflow is fully heated within the housing 70 and has a more efficient path, thereby improving the heat exchange effect of the phase change heat exchange device 100.
[0060] Please see Figure 6 In some embodiments, the heat sink 52 includes a plurality of heat sink fins 522;
[0061] The plurality of heat dissipation fins 522 are spaced apart along a first direction, and a flow channel 523 is formed between two adjacent heat dissipation fins 522. The driving member 51 is used to drive airflow to flow through the flow channel 523.
[0062] Understandably, the heat sink 52 includes multiple heat sink fins 522, and the multiple heat sink fins 522 are spaced apart along the first direction. A flow channel 523 is formed between two adjacent heat sink fins 522 to allow airflow to pass through. In order for the heat sink fins 522 to absorb heat better, the drive member 51 is set in the recess 521. When the airflow is driven by the drive member 51, the airflow can be heated through the flow channel 523 between two adjacent heat sink fins 522. This makes the airflow near the heat sink fins 522 gradually heated, so as to raise the temperature of the entire room and realize the heat exchange of the energy storage device.
[0063] Please see Figure 7 In some implementations, it also includes: a support component 80;
[0064] The support assembly 80 is disposed inside the housing 20, and the support assembly 80 is provided with a plurality of mounting parts 81, which are used to install the phase change energy storage device 10.
[0065] Understandably, a support assembly 80 is provided inside the housing 20, which divides the housing 20 into multiple mounting sections 81. Each mounting section 81 can install a phase change energy storage device 10, thus enabling the first cavity 21 and the second cavity 21 to store more phase change energy storage devices 10, thereby increasing the overall energy storage capacity of the phase change heat exchanger 100. At the same time, the simultaneous energy storage of multiple phase change energy storage devices 10 can also improve the energy storage efficiency of the energy storage device.
[0066] Please see Figure 7 In some embodiments, the support assembly 80 includes: a plurality of first support members 82;
[0067] A plurality of the first support members 82 are spaced apart in the housing 20 along a first direction, and an mounting portion 81 is formed between two adjacent first support members 82.
[0068] Understandably, the support assembly 80 includes a plurality of first support members 82, which are spaced apart in the housing 20 along a first direction. This creates a plurality of spaces (i.e., mounting portions 81) within the housing 20 that can accommodate phase change energy storage units 10, allowing the housing 20 to accommodate more phase change energy storage units 10. After being installed in the housing 20, the phase change energy storage unit 10 can release energy. After releasing energy, it can be removed from the first cavity 21 or placed in the housing 20 for recharging via the energy replenishment assembly 60. Once the phase change energy storage unit 10 has finished storing energy, it can release heat again.
[0069] Understandably, the first support member 82 can also be configured as a heat-conducting member 40, and the first support member 82 is connected to the heat collector 30 so that the heat of the phase change energy storage device 10 can be conducted to the heat-conducting member 40 through the first support member 82.
[0070] Please see Figure 8 In some embodiments, the side wall of the housing 20 has a cavity 21, and the housing 20 is provided with a water inlet 22 and a water outlet 23, both of which are connected to the cavity 21 of the housing 20.
[0071] Understandably, the side wall of the shell 20 is provided with a cavity 21 (the shell 20 has a certain thickness, which can be understood as a cuboid, and the cavity 21 is provided in the cuboid). The side wall of the shell 20 is provided with an inlet 22 and an outlet 23. Fluid or gas can be introduced into the cavity 21 through the inlet 22 and the outlet 23, so that the gas or fluid can heat the shell 20. This can heat the shell 20, keep it warm, or cool it, so that the phase change energy storage device 10 inside the shell 20 can store energy, or keep the shell 20 warm.
[0072] Please see Figure 8 In some embodiments, it also includes: a plurality of deflector plates 24;
[0073] The side wall of the housing 20 has a cavity 21, and the housing 20 is provided with a water inlet 22 and a water outlet 23, both of which are connected to the cavity 21 of the housing 20.
[0074] Multiple guide plates 24 are alternately arranged in the cavity 21, and the multiple guide plates 24 form a guide channel in the cavity 21.
[0075] Understandably, multiple guide plates 24 are provided on the inner wall of the cavity 21. These multiple guide plates 24 are arranged alternately on the inner wall of the cavity 21, so that the multiple guide plates 24 arranged alternately can form a guide channel in the cavity 21. Air or fluid can pass through the guide channel, so that hot water can flow along the path of the guide channel to ensure that the fluid or gas can heat the shell 20 evenly. At the same time, the guide channel can also extend the path length of the guide channel, thereby increasing the heat absorption efficiency of the heat exchange medium.
[0076] Understandably, when gas or fluid passes through the flow channel, it can also cool or heat the outer shell. The temperature increase or decrease depends on the current temperature of the phase change energy storage device 10. When the phase change energy storage device 10 is storing cold, the gas or fluid can cool the outer shell, thus making the temperature inside the shell 20 relatively low. When the phase change energy storage device 10 is storing heat, the gas or fluid can heat the outer shell, thus making the temperature inside the shell 20 relatively high, thereby achieving the purpose of heating the inside of the shell 20.
[0077] Please see Figure 8 In some embodiments, it also includes: heat exchanger 91, first heat exchange tube 92, and second heat exchange tube 93;
[0078] The heat exchanger 91 is disposed on one side of the housing 20. The water inlet 22 is connected to the heat exchanger 91 through the first heat exchange tube 92, and the water outlet 23 is connected to the heat exchanger 91 through the second heat exchange tube 93.
[0079] Understandably, there are a first heat exchange tube 92, a second heat exchange tube 93, and a heat exchanger 91. In order to allow the water in the heat exchanger 91 to enter the accommodating cavity of the shell 20, an inlet 22 and an outlet 23 are provided on the side wall of the shell 20, and the heat exchanger 91 is provided with a water supply port and a water return port. One end of the first heat exchange tube 92 is connected to the inlet 22, and the other end of the first heat exchange tube 92 is connected to the water supply port. One end of the second heat exchange tube 93 is connected to the outlet 23, and the other end of the first heat exchange tube 92 is connected to the water return port. In this way, the water in the heat exchanger 91 can be supplied to the cavity 21 of the shell 20.
[0080] Understandably, after the hot water enters the cavity 21, it flows, thus heating the shell 20 and providing it with heat, while also providing some insulation. When the heat source 61 first starts operating, the shell 20 is at a low temperature. The heat from the heat exchanger 91, the first heat exchange tube 92, and the second heat exchange tube 93 can transfer heat from the heat exchanger 91 to the shell 20, thereby improving the heating efficiency of the energy storage device.
