[0056] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0057] In combination Figures 1 to 6 As shown, the embodiments of the present disclosure provide an electric card refrigeration device, which comprises an electric card module 10, a first heat exchange assembly 20 and a second heat exchange assembly 30. The electric card module 10 generates an electric card effect by switching on and off with an external power supply. The first heat exchange assembly 20 is arranged on one side of the electric card module 10 and is in thermal conductive connection with the electric card module 10 to exchange heat with the electric card module 10 and transfer the heat of the electric card module 10 to dissipate heat. The second heat exchange assembly 30 is arranged on the other side of the electric card module 10 and is in thermal conductive connection with the electric card module 10 to transfer the cold of the electric card module 10. Wherein, the electric card module 10 triggers the second heat exchange assembly 30 to work by being powered off, so that the cold generated by the electric card effect of the electric card module 10 is transferred to the second heat exchange assembly 30 to refrigerate.
[0058] The electric card refrigeration device provided by the embodiment of the present disclosure is used, the heat generated by the electric card module 10 is transferred to the first heat exchange assembly 20 for heat dissipation and cooling, the cold energy generated by the electric card module 10 is transferred to the second heat exchange assembly 30, and is transferred to the associated equipment through the second heat exchange assembly 30 for refrigeration; wherein, the electric card module 10 generates cold energy when being powered off, the second heat exchange assembly 30 is triggered to work when the electric card module 10 is powered off, so that the second heat exchange assembly 30 transfers the cold energy generated by the electric card module 10 outward, realizing the separate use of the cold energy of the electric card module 10, and further realizing the purpose of industrialized mass production application.
[0059] The electric card module 10 is connected with an external power supply, the external power supply is periodically powered on and powered off with the electric card module 10, and the electric card module 10 thus realizes periodic heat release and heat absorption. The first heat exchange assembly 20 is fixedly and heat-conductively connected with the electric card module 10, and continuously works regardless of whether the electric card module 10 is powered on or powered off. In the case that the electric card module 10 is powered on and releases heat, the first heat exchange assembly 20 receives the heat generated by the electric card module 10 and performs heat dissipation and cooling. In the case that the electric card module 10 is powered off and absorbs heat, the second heat exchange assembly 30 works, and the cold energy generated by the electric card module 10 when absorbing heat is transferred to the second heat exchange assembly 30, and the cold energy is transferred to the corresponding device or equipment outside through the second heat exchange assembly 30, not only realizing the purpose of refrigeration, but also realizing effective separation of the heat and cold energy generated by the electric card module 10 in the electric card effect. In the case that the second heat exchange assembly 30 works, because the electric card module 10 generates cold energy when absorbing heat, the first heat exchange assembly 20 not only does not need to perform heat dissipation and cooling on the electric card module 10, but also can lower the temperature of the first heat exchange assembly 20 through the electric card module 10. In the case that the electric card module 10 is powered on and releases heat, because the temperature of the first heat exchange assembly 20 is low, the time for the temperature of the first heat exchange assembly 20 to rise is prolonged, thereby improving the heat dissipation effect on the electric card module 10.
[0060] Optionally, the first heat exchange assembly 20 comprises a base 201, an inflation plate 202 and a fin group 207, the base 201 is heat-conductively connected with the electric card module 10 to receive the heat generated by the electric card module 10; the inflation plate 202 is heat-conductively connected with the base 201, and a flow path for the flow of heat transfer medium is constructed in the inflation plate 202; the fin group 207 comprises a plurality of fins and is heat-conductively connected with the inflation plate 202; wherein, the base 201 and the fin group 207 are respectively arranged on two sides of the inflation plate 202, so that the heat of the base 201 is transferred to the inflation plate 202, and the heat transfer medium in the inflation plate 202 is phase-changed by heat to transfer the heat to the fin group 207 for heat dissipation and cooling.
[0061] The base 201 is in heat-conducting connection with the electric card module 10, and the heat generated by the electric card module 10 is transferred to the base 201, and then to the inflation plate 202, and then to the fin group 207 through the phase change of the heat transfer medium in the inflation plate 202, so as to quickly transfer the heat generated by the electric card module 10 outward, and improve the heat dissipation efficiency of the electric card module 10.
[0062] The inflation plate 202 is filled with heat transfer medium that can be phase-changed by heat, and the inflation plate 202 is configured with flow paths for the heat transfer medium to flow. The heat transfer medium flows along the flow paths so that the heat transfer medium is uniformly distributed in the inflation plate 202 to improve the uniformity of the inflation plate 202. In actual application, the inflation plate 202 is vertically arranged or obliquely arranged, the base 201 is located at the relatively low end of the inflation plate 202, and the fin group 207 is located at the relatively high end of the inflation plate 202. In this way, it can be ensured that the heat of the base 201 is transferred to the liquid heat transfer medium in the inflation plate 202, so that the liquid heat transfer medium is phase-changed by heat, and the heat transferred by the gaseous heat transfer medium in the inflation plate 202 is dissipated and cooled by the fin group 207, thereby improving the heat dissipation efficiency of the first heat exchange assembly 20.
[0063] It should be noted that the "inflation plate" in this paper can be understood as a plate structure with flow channels inside for the heat transfer medium to flow, and the heat transfer medium flows in the inflation plate to transfer heat. The "inflation plate" in this paper is not limited to the inflation structure, and other structures that can achieve the above purpose are also available.
[0064] The base 201 and the fin group 207 are respectively arranged on both sides of the inflation plate 202, the liquid heat transfer medium in the inflation plate 202 is phase-changed by heat to become gaseous heat transfer medium, and flows upward and to the opposite side along the flow paths, and flows to the end where the fin group 207 is located, and transfers heat to the fin group 207, and is dissipated and cooled by the fin group 207. After the gaseous heat transfer medium is dissipated and cooled, it condenses into liquid heat transfer medium and flows downward along the flow paths to the end where the base 201 is located, and performs the next heat dissipation cycle.
[0065] The fin group 207 includes a plurality of fins, and the fins are perpendicular to the inflation plate 202, so that each fin is in heat-conducting connection with the inflation plate 202 to improve the heat dissipation efficiency of the fin group 207 on the inflation plate 202. The fin group 207 can be an aluminum extrusion heat sink.
[0066] It should be noted that the heat transfer medium is a phase-changeable heat transfer working medium. For example, refrigerant, but not limited to refrigerant.
[0067] Optionally, the inflation plate 202 includes a main body 203 and a bending portion 204, the main body 203 is configured with flow paths; and the bending portion 204 is bent and extended from the edge of the main body 203 to a first direction to strengthen the strength of the inflation plate 202.
[0068] The inflation portion of the inflation plate 202 is located in the main body 203, and the heat transfer medium flows in the flow path in the main body 203. The bending portion 204 extends in a first direction from the edge of the main body 203, and the bending portion 204 is arranged along the circumference of the main body 203. The relative circumferential increase of the rib plate design improves the strength of the inflation plate 202, and can prevent the first heat exchange assembly 20 from being deformed and damaged during installation and transportation.
[0069] Optionally, the bending portion 204 bends from the main body 203 to the fin group 207. In this way, the bending portion 204 can be regarded as a fin, and the bending portion 204 and the fin group 207 together dissipate heat from the inflation plate 202.
[0070] Optionally, the inflation plate 202 includes an evaporation portion 205 and a condensation portion 206. The evaporation portion 205 is in thermal contact with the electric card module 10. The condensation portion 206 is arranged opposite to the evaporation portion 205 and is in thermal contact with the fin group 207. The flow path in the inflation plate 202 is connected to the evaporation portion 205 and the condensation portion 206, so that the heat transfer medium in the evaporation portion 205 changes phase after being heated, moves to the condensation portion 206, and returns to the evaporation portion 205 after being condensed by the condensation portion 206.
[0071] The evaporation portion 205 of the inflation plate 202 receives heat generated by the electric card module 10, and transfers the heat to the condensation portion 206 through the heat transfer medium in the evaporation portion 205. The gaseous heat transfer medium in the condensation portion 206 transfers heat to the fin group 207, and dissipates heat through the fin group 207. The condensed liquid heat transfer medium returns to the evaporation portion 205 under the action of gravity, and performs the next heat cycle. In this way, the heat of the inflation plate 202 is transferred from the evaporation portion 205 to the condensation portion 206 in a single direction and efficiently.
[0072] Optionally, the first heat exchange assembly 20 further includes a fan 208 arranged on the side of the fin group 207, so that the airflow blown by the fan 208 flows through the gap between adjacent fins of the fin group 207 to dissipate heat from the fins.
[0073] The fan 208 is arranged on the side of the fin group 207. When the electric card module 10 is powered on and generates heat, the fan 208 operates, and the airflow blown by the fan 208 flows through the fins of the fin group 207 and the inflation plate 202 to dissipate heat from the inflation plate 202 and the fins.
[0074] The airflow blown by the fan 208 flows in parallel with the fins of the fin group 207, so that the airflow flows through the gap between adjacent fins, blows heat away from the fins through the airflow, and thus reduces the temperature of the fins.
[0075] Optionally, the second heat exchange assembly 30 comprises a heat transfer element 301, a heat exchanger 302 and a water pump 303 assembly, the heat transfer element 301 is in heat conduction connection with the electrocaloric module 10; the heat exchanger 302 is used for refrigeration; the water pump 303 assembly comprises the water pump 303 and a pipeline 304 connecting the heat transfer element 301 and the heat exchanger 302, the water pump 303 is arranged in the pipeline 304 and controls the opening and closing of the pipeline 304; wherein the electrocaloric module 10 is powered off to trigger the water pump 303 to work, so that the liquid in the pipeline 304 is in a flowing state, the electrocaloric module 10 is powered off to absorb heat, the liquid cools the liquid flowing through the heat transfer element 301, and the cold energy is transferred to the heat exchanger 302 through the liquid.
[0076] The pipeline 304 of the second heat exchange assembly 30 is connected in series with the heat transfer element 301, the water pump 303 and the heat exchanger 302. The pipeline 304 flows with a heat transferable liquid. The pipeline 304 controls the flow of the liquid through the water pump 303. The heat transferable liquid can be water, refrigerant or other heat transfer medium that can be phase changed by heat.
[0077] In the case that the electrocaloric module 10 is powered off to absorb heat, the second heat exchange assembly 30 works, the heat transfer element 301 is in heat conduction connection with the electrocaloric module 10, and the water pump 303 in the water pump 303 assembly works to make the liquid in the pipeline 304 circulate and flow. The liquid in the pipeline 304 exchanges heat with the electrocaloric module 10 when flowing through the heat transfer element 301, the cold energy generated by the electrocaloric module 10 is transferred to the heat transfer element 301, and then continues to flow to transfer the cold energy to the heat exchanger 302, so as to transfer the cold energy and achieve the purpose of refrigeration.
[0078] The embodiment of the present disclosure adopts the intermittent fluid heat transfer mode to efficiently transfer the cold energy generated by the electrocaloric module 10 in the electrocaloric effect, and realizes the effective separation of the cold energy from the electrocaloric module 10.
[0079] Optionally, the heat transfer element can be a water cooling head. However, the heat transfer element is not limited to the water cooling head, for example, other elements with heat transfer function and internal liquid circulation function can also be used.
[0080] Optionally, the electrocaloric module 10 comprises: an electrocaloric assembly 101 comprising an electrocaloric element and a thin film electrode covering and adhering to opposite sides of the electrocaloric element; a heat conduction assembly comprising a first heat conduction element 102 and a second heat conduction element 103 arranged opposite to each other, the first heat conduction element 102 and the second heat conduction element 103 are respectively in heat conduction connection with the opposite sides of the electrocaloric assembly 101 to transfer heat with the electrocaloric assembly 101; wherein the thin film electrode is connected with an external power supply, the electrocaloric module 10 is powered on to release heat, the heat is transferred to the first heat exchange assembly 20 through the first heat conduction element 102, the electrocaloric module 10 is powered off to absorb heat, and the cold energy is transferred to the second heat exchange assembly 30 through the second heat conduction element 103.
[0081] The thin film electrode covers and adheres to the side of the electrocaloric element to form the electrocaloric assembly 101, which not only makes the electrocaloric element on-off, generates the electrocaloric effect, but also helps to make the surface of the electrocaloric assembly 101 flat, so that when the electrocaloric assembly 101 is in thermal contact with the heat conduction assembly, the effective contact area between the two can be guaranteed, and the heat transfer efficiency between the electrocaloric assembly 101 and the heat conduction assembly is improved. In addition, the electrocaloric module 10 is packaged by arranging the electrocaloric assembly 101 between the first heat conduction element 102 and the second heat conduction element 103, so that the electrocaloric assembly 101 can be packaged for use, thereby realizing the industrialized preparation and application of the electrocaloric module 10.
[0082] The electrocaloric element can be one or more. The number of electrocaloric elements can be selected according to actual needs, so that the electrocaloric module 10 achieves the purpose of controllable cold. In the case where the electrocaloric assembly 101 includes multiple electrocaloric elements, the multiple electrocaloric elements are arranged side by side and located in the same plane.
[0083] The thin film electrode covers and adheres to the side of the electrocaloric element to form the electrocaloric assembly 101, which not only makes the electrocaloric element on-off, generates the electrocaloric effect, but also helps to make the surface of the electrocaloric assembly 101 flat, so that when the electrocaloric assembly 101 is in thermal contact with the heat conduction assembly, the effective contact area between the two can be guaranteed, and the heat transfer efficiency between the electrocaloric assembly 101 and the heat conduction assembly is improved. In addition, the electrocaloric module 10 is packaged by arranging the electrocaloric assembly 101 between the first heat conduction element 102 and the second heat conduction element 103, so that the electrocaloric assembly 101 can be packaged for use, thereby realizing the industrialized preparation and application of the electrocaloric module 10.
[0084] The electrocaloric assembly 101 is in thermal contact with the heat conduction assembly, especially by arranging the electrocaloric assembly 101 between the first heat conduction element 102 and the second heat conduction element 103. In this way, in the case of heat release of the electrocaloric assembly 101, the heat released by the electrocaloric assembly 101 is transmitted to the first heat conduction element 102, and the heat is transmitted to the first heat exchange assembly 20 through the first heat conduction element 102 for heat dissipation. In the case of heat absorption of the electrocaloric assembly 101, the electrocaloric assembly 101 absorbs heat to produce cooling, and the generated cooling is transmitted to the second heat exchange assembly 30 through the second heat conduction element 103, and the cooling is transmitted outward through the second heat exchange assembly 30 to achieve the purpose of refrigeration.
[0085] Optionally, the first heat conduction element 102 can be a heat conduction sheet. Optionally, the second heat conduction element 103 can be a heat conduction sheet.
[0086] Optionally, the electrocaloric element can be a circular structure or a square structure. The specific size of the electrocaloric element is determined as needed. The electrocaloric element can be made of ferroelectric material powder by proportioning, ball milling, drying, grinding, tabletting and sintering. However, the material of the electrocaloric element is not limited to being made of ferroelectric material.
[0087] For the convenience of description and distinction, the thin film electrodes on both sides of the electric card element are defined as the first thin film electrode and the second thin film electrode. The first thin film electrode is in thermal conductive connection with the first thermal conductive element 102, and the second thin film electrode is in thermal conductive connection with the second thermal conductive element 103. The first thin film electrode and the second thin film electrode are respectively provided with pins for external connection of a power supply.
[0088] In actual application, in order to improve the thermal conductive efficiency and ensure safety, the first thermal conductive element 102 and the second thermal conductive element 103 are selected from high-thermal-conductive insulating materials, such as aluminum nitride, silicon carbide, gallium nitride, boron nitride, and aluminum oxide. In addition, the first thermal conductive element 102 and the second thermal conductive element 103 can have a certain thickness to store cold or heat.
[0089] Optionally, the opposite sides of the electric card element are coated with conductive paint to enable the electric card element to be attached to and in conductive connection with the thin film electrodes.
[0090] The opposite sides of the electric card element are coated with conductive paint, which not only enables the electric card element to be attached to and in conductive connection with the thin film electrodes, but also fills the uneven areas on the surface of the electric card element to keep the outer side of the electric card assembly 101 formed by the electric card element and the thin film electrodes flat. In the case where the electric card assembly 101 is in thermal conductive connection with the thermal conductive sheet assembly, the effective contact area between the side of the electric card assembly 101 and the side of the thermal conductive sheet is ensured, and the heat transfer efficiency is improved.
