Description

Technical Field

[0001] The present invention relates to the technical field of touch screens, and in particular to a touch screen with a heat dissipation structure. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel," is an inductive liquid crystal display device that receives input signals from a contact or other source. When a graphical button on the screen is touched, the on-screen tactile feedback system activates various connected devices according to pre-programmed instructions. It can replace mechanical button panels and create vivid audio and video effects through the LCD display. As the latest computer input device, the touch screen is currently the simplest, most convenient, and most natural form of human-computer interaction. With the rapid advancement of high technology, touch screens are increasingly being used in field laboratory instruments. The heat generated by laboratory instruments during operation causes the internal temperature of the equipment to rise rapidly. If this heat is not dissipated promptly, the equipment will continue to heat up, causing components to become inoperable due to overheating, and the instrument's stability will be reduced. Therefore, heat removal from PCB circuit boards is crucial.

[0003] Chinese Patent Publication No. CN222028592U discloses an electronic touch screen heat dissipation structure, comprising a housing, a mounting slot extending leftward and rightward from the middle of the left end of the housing, a heat dissipation assembly fixedly mounted within the mounting slot, support blocks fixedly mounted on the left and right lower ends of the housing, connecting brackets fixedly mounted on the front and rear inner sides of the housing, and a main plate disposed between the two connecting brackets. The electronic touch screen heat dissipation structure described in this utility model can enhance heat dissipation of the main plate by providing a heat dissipation assembly. Under wind force, air can circulate around the main plate, and heat dissipated from the main plate can be discharged through the air vents and heat dissipation holes under the action of air flow, thereby enhancing the heat dissipation effect of the main plate. The housing and the limiting brackets can enhance the protection function of the main plate and strengthen the stability of the main plate. Therefore, the above technical solution has the following problems: it cannot actively cool the touch screen, and the touch screen has low heat dissipation performance and low heat dissipation efficiency. Summary of the Invention

[0004] To this end, the present invention provides a touch screen with a heat dissipation structure to overcome the problems in the prior art of being unable to actively cool the touch screen, and having low heat dissipation performance and low heat dissipation efficiency.

[0005] To achieve the above object, the present invention provides a touch screen with a heat dissipation structure, comprising: A touch screen module comprising a touch layer and a heat dissipation layer, wherein the heat dissipation layer comprises a graphene layer laminated to the touch layer; a heat conduction module connected to the heat dissipation layer and configured to perform heat exchange with the heat dissipation layer to remove heat from the touch screen; a detection module connected to the touch screen module and the heat conduction module, for obtaining the surface temperature of the touch layer, the temperature of the heat dissipation layer, and the temperature of the heat conduction module; a control module, connected to the touch screen module, the heat conduction module, and the detection module, respectively, for determining whether the heat conduction layer is turned on based on the surface temperature of the touch layer and the temperature of the heat dissipation layer, and determining the heat conduction efficiency of the heat conduction module based on the temperature difference between the temperature of the heat conduction module and the temperature of the heat dissipation layer; The control module is further configured to establish a heat dissipation learning model based on the temperature of the touch layer and the usage time of the touch screen, so as to control the heat dissipation efficiency of the heat conduction module based on the heat dissipation learning model.

[0006] Furthermore, the heat dissipation layer includes a graphene layer, a heat conducting layer and a phase change energy storage layer connected in sequence, wherein: The graphene layer is in contact with a side of the touch layer away from the touch surface layer to conduct heat to the heat conducting layer; The heat-conducting layer is provided with a plurality of metal heat-conducting circuits for heat exchange with the graphene layer and the phase-change energy storage layer; The phase-change energy storage layer is arranged on a side close to the outside of the touch screen to perform heat exchange with the environment.

[0007] Furthermore, a heat conducting pipe is in contact with the graphene layer to perform heat exchange with the heat dissipation layer; a plurality of one-way valves, which are arranged in the guide pipeline and are used to control the opening / closing of the heat transfer pipeline and the progress of heat exchange; A heat-conducting liquid is provided in the heat-conducting pipeline and is used as a heat exchange medium; The liquid pump is arranged in the heat conduction pipeline to control the flow rate of the heat conduction liquid to adjust the heat conduction efficiency of the heat conduction module.

[0008] Furthermore, a metal conductive shell is provided outside the phase-change energy storage layer, and the metal conductive shell is in contact with the outside of the touch screen to exchange heat with the external environment.

[0009] Furthermore, the control module determines whether the heat conducting layer is turned on based on a comparison result of the surface temperature of the touch layer and the temperature of the heat dissipation layer, wherein: If the surface temperature of the touch layer is greater than or equal to the temperature of the heat dissipation layer, the control module determines that the heat conduction layer is turned on; If the surface temperature of the touch layer is lower than the temperature of the heat dissipation layer, the control module determines that the heat conduction layer is not started to work.

[0010] Furthermore, the control module controls whether the one-way valve is opened or not according to the result of judging whether the heat conducting layer is opened or not. If it is determined that the heat transfer layer is in operation, the control module controls each one-way valve to open; If it is determined that the heat conducting layer is not working, the control module controls each one-way valve to close.

[0012] Furthermore, the control module determines the heat conduction efficiency of the heat conduction module according to the temperature difference between the heat conduction liquid temperature of the heat conduction module and the temperature of the graphene layer of the heat dissipation layer. If the temperature difference is greater than a preset temperature difference, the control module increases the heat conduction efficiency to the heat conduction module; The thermal conductivity is proportional to the absolute value of the temperature difference.

[0013] Furthermore, the control module is further configured to determine whether to pre-control the heat conduction module to start working according to a comparison result between the heating time predicted by the heat dissipation learning model and the preset time; If the temperature rise time predicted by the heat dissipation learning model is less than or equal to the preset time, it is determined to control the heat conduction module to start working in advance; If the temperature rise time predicted by the heat dissipation learning model is greater than the preset time, it is determined that the heat conduction module is controlled not to start working in advance.

[0015] It can be understood that the preset energy storage temperature is used to characterize the heat absorption and heat release characteristics of the phase change energy storage material, and is generally set to the phase change temperature value of the corresponding phase change energy storage material.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the touch screen with a heat dissipation structure of the present invention is provided with a graphene layer for strong heat conduction, which can effectively transfer the temperature of the touch screen to the heat dissipation layer, thereby achieving efficient heat dissipation. In addition, by providing a thermal conduction module, heat exchange can be carried out in a timely manner to cool the graphene layer, effectively ensuring the heat dissipation efficiency.

[0017] Furthermore, the touch screen with a heat dissipation structure of the present invention is provided with a phase change energy storage layer, and heat is exchanged with the graphene layer through the metal heat conductive circuit in the heat conductive layer, so that heat can be actively exchanged with the touch layer, thereby avoiding the problem of untimely heat dissipation caused by the heat dissipation method in the prior art that can only perform heat exchange through passive ventilation.

[0018] Furthermore, the touch screen with a heat dissipation structure of the present invention can timely determine the detected temperature through the control module and control the operation of the thermal conductivity module, which can effectively identify the failure of the phase change energy storage layer or the abnormal heating state of the touch screen and perform passive heat dissipation in time. Compared with active heat dissipation, it can further improve the heat dissipation efficiency and improve the heat dissipation performance of the touch screen.

[0020] Furthermore, the control module of the touch screen with a heat dissipation structure of the present invention determines whether to pre-control the thermal conductivity module to start working based on the comparison result of the heating time predicted by the heat dissipation learning model and the preset time.
