Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[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. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. 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] An air conditioner is a small air conditioning unit that can regulate the air in a space to maintain a certain temperature, humidity, airflow speed, cleanliness, and freshness. Currently, refrigerators in related technologies use a compressor to perform work on the refrigeration system. This system utilizes a low-boiling-point refrigerant, which absorbs cold energy during evaporation and vaporization. However, in this type of air conditioner, the compressor operates for extended periods, generating significant cooling energy and consuming considerable electrical energy.

[0042] It should be specifically noted that the first direction referred to in this utility model is as follows: Figure 5 or Figure 6 The direction shown is from top to bottom.

[0043] Therefore, this embodiment provides a heat exchange device 100 with a phase change energy storage element. The heat exchange device 100 with a phase change energy storage element can avoid generating waste heat when the heat exchange device 100 with a phase change energy storage element is heating.

[0044] Please see Figure 1 A heat exchange device 100 with a phase change energy storage component includes: a phase change energy storage component 10, a heat collector 20, and a heat dissipation component 30;

[0045] The heat collector 20 and the heat dissipation component 30 are both disposed in the heat exchange device 100 with the phase change energy storage component. The heat collector 20 is connected to the heat dissipation component 30. A heat collection section 21 is disposed on the side of the heat collector 20 away from the heat dissipation component 30. The phase change energy storage component 10 is disposed in the heat collection section 21.

[0046] The heat collector 20 is used to absorb the cold energy of the phase change energy storage device 10, and the heat dissipation device 30 is used to dissipate the cold energy of the heat collector 20.

[0047] The aforementioned heat exchanger 100 with phase change energy storage device is equipped with a heat collector 20, a heat collector section 21 on the heat collector 20, and a phase change energy storage device 10 installed on the heat collector section 21. After the phase change energy storage device 10 releases energy, the heat collector 20 collects it, and the heat dissipation device 30 dissipates the energy on the collected device into the heat exchanger 100. The airflow circulation in the heat exchanger 100 can transfer the cold energy in the heat exchanger 100 to the indoor air through the airflow circulation, thereby cooling the room and achieving the cooling effect. The heat exchanger 100 with phase change energy storage device in this utility model does not have an outdoor unit. Cooling can be achieved simply by installing the above-mentioned components indoors. Therefore, there is no need for a compressor and related refrigerant. Thus, the heat exchanger 100 with phase change energy storage device will not generate additional cooling capacity. At the same time, the heat exchanger 100 with phase change energy storage device can be used normally even without being plugged in when the phase change energy storage device 10 has energy, which can also reduce the consumption of electricity.

[0048] Understandably, a heat collector 20 is provided in the heat exchanger 100 with a phase change energy storage device. A heat collection section 21 is provided on the heat collector 20, and a phase change energy storage device 10 is installed on the heat collection section 21. After the phase change energy storage device 10 releases cold energy, the heat collector 20, which is close to the phase change energy storage device 10, can absorb the cold energy released by the phase change energy storage device 10. After absorbing the cold energy, the heat collector 20 conducts the cold energy to the heat dissipation device 30, so that the heat dissipation device 30 can release the cold energy. After the cold energy is released, it can cool the airflow in the heat exchanger 100 with the phase change energy storage device. When the airflow in the heat exchanger 100 with the phase change energy storage device 100 circulates, it can lower the indoor temperature, thus achieving the purpose of regulating the air temperature.

[0049] Please see Figure 1 and Figure 2 In some embodiments, it further includes: a housing 40;

[0050] The housing 40 has a receiving cavity 41, and the heat collection element 20, the heat dissipation element 30, and the phase change energy storage element 10 are all disposed in the receiving cavity 41;

[0051] The heat collection element 20 divides the accommodating cavity 41 into a first cavity 42 and a second cavity 43. The first cavity 42 and the second cavity 43 are connected. An air inlet 44 is provided in the first cavity 42 and an air outlet 45 is provided in the second cavity 43.

[0052] The phase change energy storage device 10 is located in the first chamber, and the heat dissipation device 30 is located in the second chamber.

[0053] Understandably, the aforementioned housing 40 is the outer shell of the heat exchange device 100 with a phase change energy storage component. The housing 40 has an internal accommodating cavity 41, in which the heat dissipation component 30, the heat collector 20, and the phase change energy storage component 10 are all disposed. The heat collector 20 is vertically disposed inside the housing 40, so that the heat collector 20 can divide the accommodating cavity 41 into a first cavity 42 and a second cavity 43. The first cavity 42 and the second cavity 43 are connected, so that the airflow in the first cavity can exchange heat with the airflow in the second cavity.

[0054] Understandably, the first cavity 42 is used to install the phase change energy storage device 10, and the heat sink 30 is located in the second cavity 43. An air inlet 44 is provided in the first cavity 42, and an air outlet 45 is provided in the second cavity 43. In this way, airflow can enter the first cavity through the air inlet 44. When the airflow enters the first cavity, it can exchange heat with the phase change energy storage device 10 as it flows through the first cavity, so as to initially cool the airflow. Then, the airflow flows to the heat sink 30 in the second cavity to cool the airflow. After that, the cooled airflow is discharged into the room through the air outlet 45 to cool the room, thereby achieving the purpose of air temperature regulation.

[0055] Please see Figure 2 In some embodiments, the air intake volume of the air inlet 44 is greater than the air outlet volume of the air outlet 45.

[0056] Understandably, the air intake volume of the air inlet 44 is greater than the air outlet volume of the air outlet 45. This creates a positive pressure environment inside the accommodating cavity 41, which accelerates the airflow within the accommodating cavity 41, thereby increasing the airflow velocity in the room and causing the room temperature to drop more quickly. This ultimately improves the cooling effect of the heat exchanger 100 with phase change energy storage components.

[0057] Please see Figure 3 and Figure 4 In some embodiments, it further includes: a drive element 90;

[0058] The driving component 90 is disposed in the second cavity 43. The heat sink 30 has a recess 33 on the side away from the heat collector 20. The driving component 90 is disposed in the recess 33. The driving component 90 is used to drive the airflow from the air inlet 44 into the accommodating cavity 41 and out from the air outlet 45.

[0059] Understandably, the heat exchanger 100 with phase change energy storage also includes a drive component 90. The drive component 90 is used to accelerate the airflow within the housing 40. To improve the heat dissipation effect of the drive component 90, a recess 33 is provided on the heat sink 30, and the drive component 90 is placed within the recess 33. The drive component 90 drives the airflow circulation near the heat sink 30, thereby allowing the airflow near the heat sink 30 to be cooled by the heat sink 30 more quickly. Simultaneously, it also allows the temperature of the heat sink 30 to drop rapidly, enabling the cooling energy of the heat conduction element 72 to be transferred to the heat sink 30 more quickly, thus accelerating the heat exchange efficiency of the heat exchanger. Placing the drive component 90 within the recess 33 allows more airflow to pass through the heat sink 30 when the drive component 90 drives the airflow, thereby improving the heat dissipation effect of the heat sink 30.

[0060] Understandably, the drive unit 90 can also accelerate the airflow from the air inlet 44 into the accommodating cavity 41 and out from the air outlet 45. Specifically, when the drive unit 90 is working, the airflow can drive the airflow in the second chamber to be discharged from the second chamber, thus making the second chamber a low-pressure space. When the second chamber becomes a low-pressure space, the airflow in the first chamber can flow into the second chamber, so the first chamber will become a low-pressure environment again. This allows the indoor air to enter the first chamber, thus enabling the indoor airflow to circulate, thereby achieving the purpose of improving the cooling effect of the heat exchanger 100 with phase change energy storage device.

[0061] Please see Figure 5 and Figure 6 In some embodiments, the heat sink 30 includes a plurality of heat sink fins 31;

[0062] The plurality of heat dissipation fins 31 are spaced apart along a first direction, and a flow channel 32 is formed between two adjacent heat dissipation fins 31. The driving member 90 is used to drive airflow to flow through the flow channel 32.

[0063] Understandably, the heat sink 30 includes multiple heat dissipation fins 31, which are spaced apart along a first direction. A flow channel 32 is formed between adjacent heat dissipation fins 31, allowing airflow to pass through, thus improving the cooling effect of the heat dissipation fins 31. When the driving component 90 drives the airflow, the airflow can pass through the flow channel 32 between adjacent heat dissipation fins 31, allowing the airflow to be cooled by the heat dissipation fins 31. Since the airflow flows over the surfaces of the two heat dissipation fins 31, it has a larger cooling area, enabling rapid cooling and further improving the cooling effect of the heat dissipation fins 31, thereby enhancing the cooling efficiency of the heat sink 30.

[0064] Please see Figure 7In some embodiments, it also includes: a plurality of support members 50;

[0065] Multiple support members 50 are spaced apart in the first chamber, and each support member 50 is provided with a mounting part 51, which is used to mount the phase change energy storage device 10.

[0066] Understandably, multiple support members 50 are spaced apart inside the shell 40. The support members 50 inside the shell 40 can divide the shell 40 into multiple mounting parts 51. Each mounting part 51 can install a phase change energy storage device 10. This allows more phase change energy storage devices 10 to be installed and stored inside the shell, thereby increasing the overall cooling capacity of the heat exchange device 100 with phase change energy storage devices. This enables the heat exchange device 100 with phase change energy storage devices to be used for a longer period of time. In the initial cooling process, the phase change energy storage devices 10 can also release a large amount of cold energy, so that the heat exchange device 100 with phase change energy storage devices can achieve rapid cooling, thereby improving the cooling effect and cooling time of the refrigerator.

[0067] Please see Figure 8 In some embodiments, it also includes: a semiconductor cooler 60 and a heat-conducting component 70;

[0068] The semiconductor cooler 60 and the heat-conducting component 70 are disposed within the heat exchange device 100 with phase change energy storage device. The semiconductor cooler 60 has a cooling surface 61 and a heating surface 62. The heating surface 62 is disposed close to the side wall of the heat exchange device 100 with phase change energy storage device. The cooling surface 61 is connected to the heat-conducting component 70, and the heat-conducting component 70 is connected to the heat collector 20.

[0069] Understandably, the heat exchange device 100 with a phase change energy storage device also includes a semiconductor cooler 60 and a heat-conducting component 70. The semiconductor cooler 60 has a cooling surface 61 and a heating surface 62, where the cooling surface 61 is used to generate cooling capacity and the heating surface 62 is used to generate heat capacity. In this embodiment, the cooling capacity generated by the semiconductor cooler is used to store energy in the phase change energy storage device 10. In order to dissipate the heat generated by the semiconductor cooler 60, the cooling surface 61 is used to generate cooling capacity and the heating surface 62 is used to generate heat capacity. The hot surface 62 is located close to the side wall of the heat exchange device 100 with the phase change energy storage device, and the cooling surface 61 is connected to the heat conduction component 70. The other end of the heat conduction component 70 is connected to the heat collector 20. In this way, the cold energy generated by the semiconductor cooler 60 can be conducted to the phase change energy storage device 10 through the heat conduction component 70. When the phase change energy storage device 10 stops releasing cold, it can absorb the cold energy on the heat collector 20 to store energy, thus enabling the phase change energy storage device 10 to complete energy replenishment.

[0070] Please see Figure 8In some embodiments, the heat-conducting component 70 includes: a heat-conducting plate 71 and a heat-conducting element 72;

[0071] The heat-conducting plate 71 is attached to the cooling surface 61, one end of the heat-conducting element 72 is connected to the heat-conducting plate 71, and the other end of the heat-conducting element 72 is connected to the heat-collecting element 20;

[0072] The heat-conducting plate 71 is used to collect the cold energy of the cooling surface 61 and transfer it to the heat collector 20 through the heat-conducting component 72.

[0073] Understandably, the heat-conducting component 70 includes a heat-conducting plate 71 and a heat-conducting element 72. The heat-conducting plate 71 is attached to the cooling surface 61, which allows the heat-conducting plate 71 to absorb the heat from the phase change energy storage device 10. The heat-conducting element 72 is connected to the heat-conducting plate 71, and the heat generated on the heat-conducting plate 71 is transferred to the heat collector 20 through the heat-conducting element 72. The heat-conducting element 72 is also connected to the heat collector 20, which can transfer the heat from the heat-conducting plate 71 to the heat collector 20. This reduces the loss of cold energy during the transfer process and allows more cold energy to be transferred to the heat collector 20, so that the phase change energy storage device 10 can better absorb cold energy for energy storage, thereby improving the energy storage efficiency of the phase change energy storage device 10.

[0074] In some embodiments, both the heat-conducting plate 71 and the heat-conducting element 72 are made of a material with high thermal conductivity.

[0075] Understandably, using materials with high thermal conductivity for both the heat-conducting plate 71 and the heat-conducting component 72 enables the cooling capacity of the phase change energy storage component 10 to be quickly transferred to the heat dissipation component 30. This accelerates energy transfer and reduces energy loss during the transfer process, thereby improving the heat dissipation and cooling efficiency of the heat exchange device 100 with the phase change energy storage component.

[0076] Please see Figure 8 In some embodiments, the sidewall of the housing 40 is provided with a heat insulation layer 80.

[0077] Understandably, a heat insulation layer 80 is provided on the side wall of the shell 40. The heat insulation layer 80 can be provided on the inner side wall of the heat exchange device 100 with phase change energy storage device, or it can be provided on the outer side wall of the heat exchange device 100 with phase change energy storage device. The heat insulation layer 80 can isolate the shell 40 from the temperature inside the refrigerator. When the temperature inside the shell 40 is low and the temperature outside the shell 40 is high, the heat insulation layer 80 can prevent the cold air inside the shell 40 from leaking out, reduce the loss of cold air in the shell 40, reduce energy waste, and also enable the condenser to have better cooling capacity when the refrigerator is cooling.

[0078] In some embodiments, the phase change energy storage device 10 can be sodium acetate trihydrate or paraffin wax, which is prepared by microencapsulation technology, that is, encapsulating the phase change material in tiny capsules.

[0079] When the phase change energy storage device 10 absorbs heat, the ambient temperature rises to the phase change temperature of the phase change material, at which point the phase change material inside the capsule begins to absorb heat. The heat absorbed by the phase change material causes it to change from a solid to a liquid state; this process is called melting. During this process, the temperature of the phase change material inside the capsule remains relatively constant because the absorbed heat is used to overcome intermolecular forces rather than to raise the temperature.

[0080] When the phase change energy storage device 10 releases heat, the liquid phase change material inside the capsule begins to release heat when the ambient temperature drops below the phase change temperature of the phase change material. The phase change material releases heat and changes from a liquid to a solid state; this process is called solidification. Similarly, the temperature remains relatively constant during this process.

The appearance of these phrases in various places in the specification does not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments.
