Description

Technical Field

[0001] This invention relates to the field of energy utilization and heat exchange technology, specifically to an integrated heat exchange device and heat exchange method with controllable energy release. Background Technology

[0002] Currently, energy utilization and heat exchange equipment is widely used in heating, industrial waste heat recovery, and other fields. In practical applications, most energy release and heat exchange equipment still mainly rely on traditional fuel combustion methods or single energy conversion modes. Such equipment generally suffers from problems such as low energy utilization rate, limited heat exchange efficiency, and relatively complex overall structure.

[0003] In addition, some energy utilization devices rely on specific external energy sources, resulting in poor system compatibility and scenario adaptability. They are difficult to deploy flexibly in application environments with large heat load fluctuations and limited installation space. Moreover, existing energy utilization and heat exchange equipment cannot achieve efficient coordination between the energy release process and the heat exchange process, and cannot meet the application requirements of high adaptability and high heat exchange efficiency.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a controllable energy release integrated heat exchange device with simple structure, high heat exchange efficiency and strong adaptability. By optimizing the collaborative design of the energy release unit and the integrated heat exchange unit, the controllability of energy release and the heat exchange efficiency are improved, thus solving the technical pain points of existing equipment.

[0006] In order to achieve the above-mentioned objectives of the present invention, the following technical solution is adopted: According to one aspect of the present invention, the present invention provides an integrated heat exchange device with controllable energy release, comprising an energy release unit, an integrated heat exchange unit, a control unit, and connecting pipelines; The energy release unit is used to achieve controllable energy release; The integrated heat exchange unit and the energy release unit are connected by a connecting pipeline; The control unit is electrically connected to the energy release unit and the integrated heat exchange unit, respectively. The energy release unit includes an outer pressure-bearing heat exchange shell, and an insulation structure is provided on the outside of the outer pressure-bearing heat exchange shell; The energy release unit and the integrated heat exchange unit form a closed thermal loop through connecting pipelines; The control unit includes a temperature sensor and a pressure sensor arranged at the output end of the energy release unit, and a controller. The controller is configured to send an energy release control command to the energy release unit and a heat exchange medium flow rate adjustment command to the integrated heat exchange unit based on the signals collected by the temperature sensor and the pressure sensor.

[0007] The integrated heat exchange device with controllable energy release of the present invention consists of four major modules: energy release unit, integrated heat exchange unit, control unit and connecting pipeline. This integrated heat exchange device with controllable energy release can be flexibly adapted to various application scenarios with large heat load fluctuations and limited space, such as residential heating, commercial building HVAC, and industrial low-grade waste heat recovery.

[0008] The integrated heat exchange unit is directly connected to the energy release unit via connecting pipes, allowing heat energy to be bidirectionally transferred in a closed loop in the form of a medium, avoiding heat loss common in traditional heat exchangers. The control unit is electrically connected to the energy release unit to monitor operating parameters such as temperature, pressure, and flow rate, ensuring that these parameters remain within set threshold ranges under different heat load conditions, effectively improving long-term operational stability and inherent safety. An insulation structure is installed on the outer side of the pressure-bearing heat exchange shell, forming a thermal resistance barrier that significantly suppresses steady-state heat conduction and natural convection heat dissipation from the energy release unit's outer shell facing the environment.

[0009] Description of the core structure of the integrated heat exchanger with controllable energy release according to the present invention: In a preferred embodiment of the present invention, the energy release unit is a closed structure; The energy release unit includes an outer pressure-bearing heat exchange shell, an internal energy release regulation structure, and a central energy storage unit; the internal energy release regulation structure is located inside the outer pressure-bearing heat exchange shell and is used to adjust the heat energy output path in response to changes in the state of the central energy storage unit.

[0010] In a preferred embodiment, the energy release unit adopts a closed bearing structure with a built-in energy storage cavity. The inner wall of the cavity is provided with a heat insulation protective layer to prevent disorderly heat loss. The energy release unit is connected to the integrated heat exchange unit through connecting pipes.

[0011] In a preferred embodiment of the present invention, the integrated heat exchange unit includes a heat exchange shell, an internal heat exchange flow channel, and a heat exchange medium inlet and outlet; the heat exchange shell is made of a material with high thermal conductivity, and the heat exchange flow channel has a spiral or labyrinth structure to increase the heat exchange area.

[0012] In a preferred embodiment of the present invention, the input end of the heat exchange channel of the heat exchange unit is connected to the connecting pipeline, and the output end is connected to the heat exchange medium outlet; the heat exchange medium inlet is provided on the heat exchange shell.

[0013] According to one aspect of the present invention, the present invention provides a heat exchange method based on the above-described integrated heat exchange device with controllable energy release, the heat exchange method comprising: S1: The energy release unit can controllably release energy and output heat energy under the command of the control unit; S2: The heat energy enters the integrated heat exchange unit through the connecting pipeline and exchanges heat with the heat exchange medium that flows in from the heat exchange medium inlet and flows out from the heat exchange medium outlet. S3: The control unit collects temperature and pressure data at the output of the energy release unit in real time, and dynamically generates and executes commands to regulate the energy release intensity of the energy release unit and the flow rate of the heat exchange medium of the integrated heat exchange unit based on the collected data.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By connecting the energy release unit and the integrated heat exchange unit through the connecting pipeline to form a closed thermodynamic loop, the pressure loss along the friction and the thermal inertia of the system are significantly reduced, and the heat transfer efficiency and dynamic response speed are improved. (2) By setting up an insulation structure on the outside of the outer pressure heat exchange shell, the steady-state heat conduction and natural convection heat dissipation of the shell facing the environment are effectively suppressed, and high energy efficiency can still be maintained under low load conditions. (3) By directly arranging temperature and pressure sensors at the output end of the energy release unit, the control unit can obtain the source thermodynamic state signal, support feedforward collaborative regulation, and avoid regulation lag and malfunction caused by end feedback. (4) By synchronously generating and executing bidirectional control commands for the energy release unit and the integrated heat exchange unit through the controller, the energy release rate and the heat exchange medium flow rate are matched in real time, ensuring that the system operates stably, safely and efficiently within a wide range of operating conditions.

[0021] See Figures 1-4 A heat exchange utilization device with controllable energy release, the device includes an energy release unit 1, an integrated heat exchange unit 2, a control unit 3 and a connecting pipeline 4.

[0022] The energy release unit 1 is a closed structure, including an outer pressure-bearing heat exchange shell 11, a release unit heat exchange channel 12, a heat energy output interface 13, an internal energy release regulation structure 14, and a central energy storage unit 15. The outer pressure-bearing heat exchange shell 11 is provided with a heat insulation structure. In this embodiment, the heat insulation structure is a nano-aerogel composite heat insulation felt. The outer pressure heat exchange shell 11 is equipped with a central energy storage unit 15; The internal energy release control structure 14 is a set of nickel-titanium alloy shape memory spring valves embedded in the inner wall of the shell. When the central energy storage unit 15 undergoes a solid-liquid phase change, causing the pressure inside the cavity to rise, the spring valves are heated and deformed to open, connecting the heat energy output interface 13 and the connecting pipe 4, thereby realizing the controllable release of heat energy.

[0023] In this embodiment, the integrated heat exchange unit 2 includes a heat exchange shell, a heat exchange unit heat exchange channel 21, a heat exchange medium inlet 211, and a heat exchange medium outlet 212; the input end of the heat exchange channel is directly connected to the output end of the connecting pipe 4, and the output end is connected to the heat exchange medium outlet 212; the heat exchange medium inlet 211 is located on the top side wall of the heat exchange shell and is connected to the input end of the heat exchange channel through an internal guide cavity to form a heat exchange channel.

[0024] In this embodiment, the control unit 3 includes a temperature sensor 31, a pressure sensor 32, and a controller 33. The temperature sensor 31 and the pressure sensor 32 are both installed at the heat output interface 13 of the energy release unit 1, which is the starting end of the connecting pipe 4. The controller 33 is a PLC module, whose input end is connected to the sensor signal, and its output end is connected to the drive circuit of the internal energy release regulation structure 14 and the electric regulating valve at the heat exchange medium inlet 211 of the integrated heat exchange unit 2. In this embodiment, the connecting pipe 4 is fixedly connected to the heat output interface 13 of the energy release unit 1 and the input end of the heat exchange channel of the integrated heat exchange unit 2, together forming a closed thermal loop.

[0025] The heat exchange method of the heat exchange utilization device with controllable energy release in this embodiment includes: S1: Under the command of the controller 33, the energy release unit 1 can controllably release thermal energy through the internal energy release regulation structure 14 and output it through the thermal energy output interface 13; S2: Heat energy passes through the heat transfer medium and enters the integrated heat exchange unit 2 via the connecting pipe 4, where it exchanges heat with the heat exchange medium that flows in from the heat exchange medium inlet 211 and flows out from the heat exchange medium outlet 212. S3: The control unit 3 continuously collects signals from the temperature sensor 31 and the pressure sensor 32. The controller 33 generates and executes in real time the opening adjustment command of the internal energy release control structure 14 and the flow adjustment command of the electric regulating valve at the heat exchange medium inlet 211 according to the preset algorithm, so as to ensure that the system maintains stable output under the condition of heat load fluctuation.

[0026] In step S1, the coordinated control controller 33 generates an energy release intensity command and a heat exchange medium flow command based on the rate of change of the signal from the pressure sensor 32 and the amplitude of the signal from the temperature sensor 31 through a preset coupling algorithm. The two commands are time-synchronized and parameter-correlated.

[0027] This embodiment is only one implementation form. Any simple substitutions or modifications made based on this structure fall within the protection scope of this invention.

[0028] It should also be noted that the heat exchange and energy absorption medium of the integrated heat exchange device with controllable energy release of this invention can be selected from solid metal plates or blocks, which are fitted to the inner wall of the cavity to achieve heat transfer through solid-state heat conduction, depending on the actual application scenario. Alternatively, molten metal can be used, circulating in a closed loop to improve heat transfer efficiency. Both forms can be combined with external induction coils to achieve synchronous output of thermal and electrical energy, further expanding the applicable scenarios and energy utilization efficiency of the device.

[0029] In summary, the integrated heat exchange device with controllable energy release of this invention has a simple overall structure, high integration, strong component versatility, low processing and assembly difficulty, and is easy to mass-produce and promote. It can simultaneously meet the needs of heat energy supply and power output, has a wide range of applicable scenarios, and has high engineering application and market promotion value.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
