Phase change material is widely used in heating devices, which can be directly set in the heat storage device for storing heat, such as the Chinese patent with publication number CN207797837U. Phase change material can also be used as a phase change capsule, such as the Chinese patent with publication number CN105802586A. Although the carriers are different, the role of phase change material is to absorb or release heat.

[0003] For the heating device, the heating amount needs to be adjusted according to the heating demand, and the temperature test and control circuit system are needed to control the heating amount, resulting in a relatively complex overall device, and stable power and control system are needed.

[0005] To achieve the above purpose, the present application provides the following technical solutions:

[0010] A phase change capsule group is arranged between the heating component and the heating component, the phase change capsule group comprises a plurality of phase change capsules, and the phase change material is arranged in the phase change capsule;

[0011] Wherein, when the phase change material is in solid state, the phase change capsule group is in a contracted state, at this time the heating component and the heat conducting component are in contact, and the heat of the heat source is transmitted to the heating component through the heating component and the heat conducting component;

[0012] When the phase change material changes from solid state to liquid state, the phase change capsule group changes from the contracted state to the expanded state, and the expanded phase change capsule group exerts stress on the heat supply component, so that the heat supply component is separated from the heat conducting component, and the heat of the heat source cannot be transmitted to the heat supply component through the heat receiving component and the heat conducting component; at this time, the heat of the heat source is transmitted to the phase change capsule group through the heat receiving component, and the heat is stored by the phase change capsule group;

[0013] The phase change capsule group provides heat for the heat supply component when releasing heat, and the phase change capsule group changes from the expanded state to the contracted state as the phase change material solidifies, so that the heat supply component is in contact with the heat conducting component.

[0014] Further, the heat supply component is provided with a limiting structure matched with the heat conducting component.

[0015] Further, the limiting structure comprises two limiting plates, and the end of the heat conducting component is located between the two limiting plates.

[0016] Further, the heat supply component is provided with an auxiliary heat transfer component opposite to the heat conducting component.

[0017] Further, the phase change capsule group is in contact with the heat receiving component and the heat supply component respectively when being in the contracted state.

[0018] Further, the phase change capsule group comprises a plurality of phase change capsule groups, and each phase change capsule group comprises at least two phase change capsules arranged in close contact with each other.

[0019] Further, the heat receiving component is provided with a heat supply component on both sides.

[0020] In summary, the present application has the following advantages:

[0021] The phase change capsule group in the present application is used for storing and releasing heat on one hand, and plays a role of switch on the other hand; that is, the volume change of the phase change material during the transition from solid state to liquid state is used to make the phase change capsule provide stress, so as to control the contact or separation between the heat supply component and the heat conducting component, realize the role of switch, and automatically adjust the heat of the heat supply component; in the process of automatic adjustment, no additional temperature measuring device and circuit control device are needed, the structure is simple, the production cost is low, the stability is good, the response is timely, the failure rate is low, and the service life is long.

[0027] Embodiment:

[0028] A self-adjusting heat supply device, referring to Figure 1 and Figure 2 , comprising a heat receiving component 2 and a heat supply component 1, and a heat conducting component 3 is arranged between the heat receiving component 2 and the heat supply component 1; one end of the heat conducting component 3 is connected with the heat receiving component 2, and the other end is a free end and is opposite to the heat supply component 1; a phase change capsule group is arranged between the heat receiving component 2 and the heat supply component 1, the phase change capsule group comprises a plurality of phase change capsules 4, and a phase change material is arranged in the phase change capsule 4; wherein when the phase change material is in a solid state, the phase change capsule group is in a contracted state, at this time, the heat supply component 1 is in contact with the heat conducting component 3, and the heat of the heat source is transmitted to the heat supply component 1 through the heat receiving component 2 and the heat conducting component 3, and the heat supply component 1 transmits the heat to a heat supply object; when the heat of the heat source is excessive, after the phase change material changes from a solid state to a liquid state, the phase change capsule group changes from a contracted state to an expanded state, and the expanded phase change capsule group exerts stress on the heat supply component 1, so that the heat supply component 1 is separated from the heat conducting component 3, then the heat of the heat source cannot be transmitted to the heat supply component 1 through the heat receiving component 2 and the heat conducting component 3, so as to automatically adjust the heat of the heat supply, and avoid that the heat supply object receives excessive heat; at this time, the heat of the heat source is transmitted to the phase change capsule group through the heat receiving component 2, and the heat is stored by the phase change capsule group; when the heat of the heat source is insufficient, the phase change capsule group releases heat to provide heat for the heat supply component 1, so as to avoid that the heat supply object receives insufficient heat, and with solidification of the phase change material, the phase change capsule group changes from an expanded state to a contracted state, so that the heat supply component 1 is in contact with the heat conducting component 3, and then the heat of the heat source continues to be transmitted to the heat supply component 1 through the heat receiving component 2 and the heat conducting component 3.

[0029] Referring to Figure 1 and Figure 2In the embodiment, the phase change capsules are used for storing and releasing heat and also play the role of switch. That is, the phase change capsules can provide stress to control the contact or separation between the heat supply component 1 and the heat conducting component 3 to realize the switching function and automatically adjust the heat of the heat supply component 1. In the automatic adjustment process, no additional temperature measuring device and circuit control device are needed, the structure is simple, the production cost is low, the stability is good, the response is timely, the failure rate is low, and the service life is long. Preferably, when the phase change capsule group is in the contracted state, the phase change capsules 4 are in contact with the heat receiving component 2 and the heat supply component 1 respectively. That is, the phase change capsules 4 in the embodiment are always in contact with the heat receiving component 2 and the heat supply component 1, thereby ensuring timely response. Preferably, the phase change capsule group includes a plurality of phase change capsule groups, and the phase change capsule group includes at least two phase change capsules 4 arranged in close contact with each other. By using the phase change capsule group, the phase change capsules 4 arranged in close contact with each other can prevent each other from transverse deformation, which is conducive to concentrating the volume change of the phase change capsules 4 in longitudinal deformation to enable the phase change capsules 4 to provide stress to the heat supply component 1. Of course, in other alternative embodiments, a separate transverse limiting component can be provided to prevent the transverse deformation of the phase change capsules 4, or the shape of the capsule skin of the phase change capsule can be designed to reduce the transverse deformation, or a structure can be provided in the capsule skin of the phase change capsule to reduce the transverse deformation, which is not limited herein.

[0030] With reference to Figure 1 and Figure 2 In the embodiment, the phase change material can be paraffin wax, which has the advantages of large latent heat of phase change, small volume change in solid-liquid phase change process, good thermal stability, no supercooling phenomenon, and low price. The small volume change in the solid-liquid phase change process is conducive to controlling the distance between the heat supply component 1 and the heat conducting component 3 after separation, thereby ensuring the overall stability of the heat supply device. The phase change temperature of the paraffin wax can be selected according to the use scenario to meet different heat supply requirements. Of course, in other alternative embodiments, metal fillers, graphite, carbon fibers and other materials can be added to the paraffin wax to adjust the required performance of the phase change capsule. At the same time, the phase change material can also use other materials, which is not limited herein. The phase change material and the capsule packaging of the phase change material in the embodiment belong to the prior art, which is not described herein.

[0031] With reference to Figure 1 and Figure 2Preferably, the heat supply component 1 is provided with a limiting structure matched with the heat conduction component 3, so as to improve the stability of the heat supply component 1. Specifically, the limiting structure includes two limiting plates 5, and the end of the heat conduction component 3 is located between the two limiting plates 5. Specifically, the heat conduction component 3 is not in contact with the limiting plate 5 in the embodiment, so as to avoid heat transfer between the heat conduction component 3 and the limiting plate 5. Of course, in other optional embodiments, the limiting plate 5 can be made of a material with poor heat conductivity, and then the heat conduction component 3 is in contact with the limiting plate 5, which is not limited here. Preferably, the heat supply component 1 is provided with an auxiliary heat transfer component 6 opposite to the heat conduction component 3. Specifically, the heat conduction component 3 is in contact with the auxiliary heat transfer component 6 to realize heat transfer. In the embodiment, the auxiliary heat transfer component 6 is used to cooperate with the heat conduction component 3, different sizes of the auxiliary heat transfer component 6 can be replaced to adjust the separation distance, at the same time, the heat conduction component 3 is avoided to be directly in contact with the heat supply component 1, and the influence of contact stress on the heat supply component 1 is also avoided, so as to prolong the service life of the heat supply component 1. Of course, in other optional embodiments, the auxiliary heat transfer component 6 can be cancelled, and the heat conduction component 3 is directly in contact with the heat supply component 1, which is not limited here. The specific structure and shape of the heat receiving component 2, the heat conduction component 3 and the heat supply component 1 can be set and adjusted according to needs, which is not limited here. Of course, in other optional embodiments, the heat supply device can also adopt a multi-layer structure, for example, the heat receiving component 2 is provided with heat supply components 1 on both sides, which is not limited here.
