Description

Technical Field

[0001] The present invention relates to the technical field of phase change energy storage, and in particular to a mobile phase change heat and cold storage device and system. Background Art

[0002] Phase change material is a material that can change its state and absorb or release a large amount of latent heat within a specific temperature range. Phase change material can absorb or release a large amount of latent heat during the phase change process, which makes its heat storage density much greater than that of traditional materials. At the same time, during the phase change process, the temperature of the phase change material remains almost unchanged. Therefore, the corresponding phase change heat and cold storage device made by using a series of characteristics of phase change material can stably output heat or cold at the expected temperature, which can effectively solve the discontinuity problem in the utilization of waste heat or waste cold resources.

[0003] In actual operation, the existing phase change heat and cold storage devices are uncontrollable because the introduced heat and cold are mostly uncontrollable. At the same time, the device cannot control the stored heat and cold. As a result, the device cannot monitor and control the energy storage of the internal phase change material when storing heat and cold. After the phase change material completes the overall phase change to store energy, the excess energy cannot be stored and the phase change material is placed in a working area with a temperature beyond the set range, thereby affecting the long-term stable use of the phase change material.

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0028] See also Figures 1 to 8 The present invention provides a mobile phase-change heat and cold storage device and system: comprising a phase-change storage mechanism 101 and an installation component, wherein the installation component comprises a mobile frame 102, a temperature sensor 103, an import component and an export component, wherein the import component comprises an import main frame 201, an adapter frame 202 and a control component, wherein the export component comprises an export main frame 301, a one-way valve 302 and a withdrawal component, wherein the control component comprises a rotating valve block 203 and a control motor 204, and wherein the withdrawal component comprises an intake box 303, a plug plate 304 and a driving cylinder 305. The above-mentioned scheme solves the problem that the heat and cold amount introduced in the existing phase-change heat and cold storage device are mostly uncontrollable during actual operation, and the device is also unable to control the stored cold amount and heat, resulting in the device being unable to monitor and control the energy storage of the internal phase-change material during heat and cold storage. When the phase-change material completes the overall phase change to store energy, the excess energy cannot be stored, and the phase-change material is placed in a working area with a temperature beyond the set range, thereby affecting the long-term stable use of the phase-change material.

[0029] Further, it includes a phase change storage mechanism 101 and an installation component; the installation component includes a moving frame 102, a temperature sensor 103, an import component and an export component;

[0030] A plurality of phase change storage mechanisms 101 are arranged in the mobile rack 102, and each of the phase change storage mechanisms 101 is provided with the temperature sensor 103. The introduction component is connected to the mobile rack 102 for controlling the conduction of the introduced energy-releasing medium, and the export component is connected to the mobile rack 102 for exporting the energy-releasing medium that has completed energy absorption.

[0031] Specifically, the phase change storage mechanism 101 includes an insulation box, a spiral conduction tube and a phase change medium box. The shell of the phase change medium box is a heat-conducting material. The spiral conduction tube is wound on the shell of the phase change medium box. The feed end and the discharge end of the spiral conduction tube are the feed end and the discharge end of the entire phase change storage mechanism 101. The energy-releasing medium is introduced through the spiral conduction tube, and then the energy emitted by the introduced energy-releasing medium is stored through the phase change medium arranged inside the phase change medium box, thereby completing the corresponding energy storage. After the energy storage, the insulation box arranged on the outer layer can prevent the stored energy from dissipating, thereby ensuring the stability of the storage.

[0032] The bottom of the mobile frame 102 is provided with a plurality of universal wheels, and the universal wheels can facilitate the user to drive the entire energy storage device. At the same time, each of the phase change storage mechanisms 101 is provided with the temperature sensor 103, and the temperature measuring end of the temperature sensor 103 cooperates with the inside of the phase change storage mechanism 101, so as to be able to provide feedback on the energy storage situation inside the phase change storage mechanism 101. The user can judge the actual phase change situation of the phase change material inside the phase change storage mechanism 101 through the temperature sensed by the temperature sensor 103;

[0033] In actual operation, the external energy-releasing medium is introduced through the introduction component. Under the distribution control box of the introduction component, the multiple phase change storage mechanisms 101 arranged in the mobile rack 102 can collect energy one by one. At the same time, the energy storage status of the designated phase change storage mechanism 101 is monitored through the temperature sensor 103 provided on the corresponding phase change storage mechanism 101. After the temperature detected by the temperature sensor 103 exceeds the preset range, it is ensured that the corresponding phase change storage mechanism 101 can no longer continue to store energy. In this way, the introduction component can introduce the energy-releasing medium into the remaining phase change storage mechanisms 101 for energy storage to avoid energy loss.

[0034] Furthermore, the import main frame 201 is installed on the movable frame 102; each phase change storage mechanism 101 is provided with the adapter frame 202, the adapter frames 202 provided on adjacent phase change storage mechanisms 101 are connected through pipelines, and the adapter frame 202 provided on the phase change storage mechanism 101 close to the import main frame 201 is connected to the import main frame 201 through corresponding pipelines; the control component is installed on the adapter frame 202, and is used to control the conduction relationship inside the adapter frame 202.

[0035] Furthermore, the rotating valve block 203 is rotatably mounted on the adapter frame 202; the output shaft of the control motor 204 is connected to the rotating valve block 203, and the control motor 204 is fixedly mounted on the rotating frame.

[0036] When this embodiment is in use, the export main frame 301 is arranged on the mobile frame 102. Two rows of phase change storage mechanisms 101 are arranged on the mobile frame 102 in this solution. The phase change storage mechanism 101 near the export main frame 301 is directly connected to the export main frame 301 through the corresponding pipeline and the adapter frame 202, and the phase change storage mechanism 101 arranged thereafter is connected to the adjacent mechanism through the correspondingly arranged adapter frame 202 and the pipeline. The adapter frame 202 is provided with a total of three joints. The three joints of the adapter frame 202 arranged near the export main frame 301 are respectively connected to the export main frame 301 and the corresponding phase change storage mechanism 101. The feed end and the adapter frame 202 at the rear are connected, and the three joints of the adapter frame 202 in the middle are respectively connected to the adapter frame 202 at the front side, the rotating frame at the rear side and the corresponding feed end of the phase change storage mechanism 101. As for the three joints of the adapter frame 202 arranged at the very end, only two joints are respectively connected to the adapter frame 202 at the front side and the corresponding feed end of the phase change storage mechanism 101, and the vacant joint of the adapter frame 202 arranged at the very end can be used to continue to connect a new adapter frame 202 and the corresponding phase change storage mechanism 101, so that the user can control the installation quantity of the phase change storage mechanism 101 according to the actual operation situation;

[0037] The rotating valve block 203 is rotatably installed in the adapter frame 202. The rotating valve block 203 is driven by the control motor 204. The rotating valve block 203 can block one of the three joints inside the adapter frame 202. The corresponding connectivity of the three joints of the adapter frame 202 can be controlled by rotating the rotating valve block 203, thereby controlling the introduced energy-releasing medium.

[0038] During actual operation, the adapter frame 202 at the very end needs to ensure the sealing of unconnected joints, and the remaining adapter frames 202 need to be adjusted in real time according to the corresponding control system. When energy storage starts, the connecting frame close to the export main frame 301 needs to seal the connection port with the subsequent connecting frame, so that the introduced energy release medium can be introduced into the corresponding phase change storage mechanism 101 for energy release storage. After the corresponding phase change storage mechanism 101 reaches the energy storage limit, the corresponding connecting frame can seal the port connected to the phase change storage mechanism 101, so that the energy release medium can be introduced into the subsequent connecting frame and the phase change storage mechanism 101. By guiding step by step, the process can be completed in sequence. The energy storage of the multiple phase change storage mechanisms 101 can be completed by the temperature conditions fed back by the temperature sensors 103 on the multiple phase change storage mechanisms 101. The energy storage conditions can be counted, which is convenient for controlling the energy storage conditions. When performing subsequent energy release, the actual energy release conditions can also be controlled by the above control method, so that both energy storage and energy release can be controlled according to the actual operating conditions. Moreover, during the energy storage and energy release process, the temperature of the phase change medium inside the phase change storage mechanism 101 can be monitored and controlled to ensure that the internal phase change material can perform a complete phase change state conversion during energy release and energy storage, thereby avoiding the phase change medium inside the phase change storage mechanism 101 being in an incomplete phase change state for a long time, thereby affecting the continuous and stable operation of the corresponding material.

[0039] Furthermore, the export main frame 301 is connected to the export ends of all the phase change storage mechanisms 101 through a pipeline; the export end of each phase change storage mechanism 101 is provided with the one-way valve 302; the extraction component is connected to the export main frame 301, and is used to quickly export the energy release medium that has completed energy release inside the phase change storage mechanism 101.

[0040] Furthermore, the suction box 303 is connected to the export main frame 301; the plug plate 304 is slidably installed in the suction box 303; the output end of the driving cylinder 305 is connected to the plug plate 304, and the driving cylinder 305 is fixedly installed on the suction box 303.

[0041] When the present embodiment is in use, the main export frame 301 is arranged on the mobile frame 102, and the main export frame 301 is composed of a plurality of four-way joints and a main export pipe. A control valve is also arranged at the output end of the main export pipe for controlling the export of the medium. The export ports of all the phase change storage mechanisms 101 are connected with the main export pipe through the plurality of four-way joints, so as to discharge the export medium of all the phase change storage mechanisms 101. By using a four-way joint in conjunction with a corresponding pipeline to connect the plurality of phase change storage mechanisms 101, a new four-way joint can be directly added when the user needs to increase the number of the phase change storage mechanisms 101, and the added phase change storage mechanism 101 can be added to the expanded export frame, so as to facilitate the unified discharge of the medium of the entire system;

[0042] The rear end of the export main frame 301 is connected to the suction box 303, and the plug plate 304 is installed inside the suction box 303. The plug plate 304 is driven by the driving cylinder 305, so that the unexported medium inside the phase change storage mechanism 101 can be extracted and discharged by moving the plug plate 304 upward in the suction box 303 in cooperation with the control valve arranged at the export end of the export main frame 301. When extracting, the control valve at the export end of the export main frame 301 needs to be closed first, and then the plug plate 304 inside the suction box 303 is moved upward to extract the unexported medium inside the phase change storage mechanism 101, and then the control valve is opened again, and then the plug plate 304 is moved downward to squeeze out the medium. During extrusion, since the export end of each phase change storage mechanism 101 is provided with the one-way valve 302, the medium inside the phase change storage mechanism 101 can only be exported from the export port and cannot be diverted, so there is no need to worry about the problem of medium backflow during the extrusion process.

[0043] Preferably, the installation assembly provided by the present invention also includes an extension slide 401, a screw adjustment mechanism 402, a shielding component and an adsorption assembly component, the shielding component includes a winding roller 501, a shielding curtain 502, a buckle column 503 and a limit pin 504, and the adsorption assembly component includes an attachment base 601, an air pump 602 and a controller 603.

[0044] Furthermore, the extension slide 401 is slidably installed on one side of the mobile frame 102; the screw adjustment mechanism 402 is installed on the mobile frame 102, and is used to drive the extension slide 401 to slide on the mobile frame 102; the shielding component is connected to the mobile frame 102, and is used to shield and protect the mobile frame 102 and the opening on the top of the extension slide 401; the adsorption assembly component is connected to the phase change storage mechanism 101, and is used to quickly complete the installation and placement of the phase change storage mechanism 101.

[0045] When the present embodiment is in use, the extension slide 401 is slidably arranged on the side of the movable frame 102, and a corresponding universal wheel is arranged at the bottom of the extension slide 401. The installation space of the movable frame 102 can be expanded by the extension slide 401, so that the user can adjust the installation space size of the entire device according to the actual number of the phase change storage mechanism 101 installed. The extension slide 401 is driven and adjusted by the screw adjustment mechanism 402, and the screw adjustment mechanism 402 is mainly composed of a corresponding screw and a motor for driving the screw to rotate. The screw of the screw adjustment mechanism 402 is matched and connected with the connecting bracket at the bottom of the extension slide 401, so that when the motor inside the screw adjustment mechanism 402 drives the corresponding screw to rotate, the extension slide 401 can be driven by the corresponding screw to move, thereby completing the adjustment of the installation space size of the entire device, so that the user can better control the energy storage situation and energy storage range of the entire device according to actual usage.

[0046] Furthermore, the winding roller 501 is rotatably mounted on one side of the movable frame 102; the shielding curtain 502 is arranged on the winding roller 501; the buckle column 503 is fixedly mounted on the extension slide 401, and is used to cooperate with the locking hole at the end of the shielding curtain 502; the limit pin 504 is connected to the winding roller 501, and is used to limit the winding roller 501.

[0047] When the present embodiment is in use, the shielding curtain 502 is rolled up on the winding roller 501, and the end of the shielding curtain 502 is provided with corresponding locking holes and handle grooves, and a plurality of through holes are provided on the cylindrical end of the winding roller 501, and the pin rod of the limiting pin 504 is convenient for matching the through hole size of the cylindrical end of the winding roller 501, so that the user can limit the winding roller 501 by setting the pin rod, and the buckle column 503 is provided on the extension slide 401, and the buckle column 503 is connected to the extension slide 401. The locking holes provided on the shielding curtain 502 are adapted so that the user can put the end of the shielding curtain 502 on the buckle column 503. The shielding curtain 502 has a certain elasticity. By laying the shielding curtain 502, the open area on the top of the movable frame 102 and the extended slide 401 can be shielded and protected to prevent foreign objects from falling into the movable frame 102 and the extended slide 401, thereby affecting the normal operation of the phase change storage mechanism 101.

[0048] Furthermore, the attachment base 601 is installed at the bottom of the phase change storage mechanism 101; the suction pump 602 is connected to the attachment base 601 and installed on the phase change storage mechanism 101; the controller 603 is electrically connected to the suction pump 602, and the controller 603 is installed on the phase change storage mechanism 101.

[0049] When the present embodiment is in use, the attachment base 601 is composed of four suction cups and a conducting bracket connecting the four suction cups, and the suction end of the suction pump 602 is connected to the conducting bracket provided on the attachment base 601 through a conduit, so that the four suction cups at the bottom of the attachment base 601 cooperate with the surface of the movable frame 102 or the extension slide 401, and then the negative pressure generated by the suction pump 602 can adsorb and fix the entire phase change storage mechanism 101 on the movable frame 102 and the extension slide 401. When the phase change storage mechanism 101 needs to be taken, the phase change storage mechanism 101 can be quickly disassembled by only reversing the airflow through the suction pump 602, so that the user can adjust the installation quantity of the phase change storage mechanism 101 more conveniently, thereby facilitating the user to control the energy storage situation of the entire device.
