Description

Technical Field

[0001] This utility model relates to the field of heat inlet technology, specifically a heat energy regulating device for a heat inlet. Background Technology

[0002] In centralized heating systems, the heat inlet is the core hub connecting the primary and secondary networks, and the performance of its heat regulation device directly affects heating stability, energy utilization, and user experience. With rising energy costs and the advancement of "dual carbon" goals, traditional heat inlet regulation technologies have gradually revealed problems such as low efficiency, slow response, and poor adaptability, making it difficult to meet the needs of modern heating systems.

[0003] Currently, most thermal inlets employ a separate regulation scheme using valves and heat exchangers. However, traditional heat exchangers often use a straight-tube structure, resulting in laminar flow of the internal fluid, low heat exchange efficiency, and difficulty in adapting to drastic changes in primary and secondary network parameters. Therefore, a thermal energy regulation device for thermal inlets is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a thermal energy regulating device for a thermal inlet, which solves the technical problems mentioned in the background art by using a spiral groove of a continuous spiral turbulence structure that can increase the heat exchange area, and a valve core that can be rotated to adjust and control the flow rate of high-temperature medium.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thermal energy regulating device for a thermal inlet includes a first pipe connected to an external high-temperature water inlet pipe, a second pipe connected to an external secondary network pipe sleeved on the outside of the first pipe, and a spiral groove provided on the inner wall of the first pipe to increase the heat exchange area, wherein the spiral groove is a continuous spiral turbulence structure.

[0007] A regulating component for adjusting the flow rate of hot water is installed at the front end of the spiral groove in the middle of the first pipe. The regulating component includes a rotatable valve core installed inside the first pipe. The valve core adjusts the flow rate of the high-temperature medium by changing the flow gap between itself and the inner wall of the first pipe through rotation.

[0008] Preferably, a heat exchange chamber is provided between the second pipe and the first pipe, and the two ends of the second pipe are respectively connected to the secondary network return water pipe and the secondary network supply water pipe.

[0009] Preferably, the depth of the spiral groove is gradually varied along the direction of medium flow, and the spiral groove gradually deepens and then gradually becomes shallower from the inlet end to the outlet end of the first pipe.

[0010] Preferably, an extension pipe is installed through the bottom of the first pipe, and the extension pipe passes through the bottom of the second pipe and is connected to the external primary network return pipe.

[0011] Preferably, the inner wall of the extension tube is provided with a temperature sensor, and the temperature sensor is electrically connected to the control module of the adjustment component.

[0012] Preferably, the regulating component further includes a connecting block disposed outside the first pipe, and a motor for driving the valve stem to rotate is mounted on the upper part of the connecting block.

[0013] Preferably, the valve stem extends through the middle of the connecting block into the interior of the first pipe, and the valve core is installed through the middle of the valve stem.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By using a nested structure for the first and second pipes, the separate valve and heat exchanger scheme is eliminated, simplifying the structure of the thermal inlet. Meanwhile, the spiral grooves of the continuous spiral turbulence structure on the inner wall of the first pipe can break the laminar flow state of the fluid, significantly increasing the heat exchange area and improving the heat exchange efficiency. The regulating component in the middle can change the flow gap by rotating the valve core, flexibly adjusting the flow rate of the high-temperature medium, thereby better adapting to the drastic changes in the parameters of the primary and secondary networks, and improving the overall performance and adaptability of the thermal energy regulation of the thermal inlet.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides: a heat energy regulating device for a heat inlet, such as... Figures 1-4 As shown, the system includes a first pipe 1 connected to an external high-temperature water inlet pipe, and a second pipe 2 connected to an external secondary network pipe, sleeved outside the first pipe 1. The inner wall of the first pipe 1 has spiral grooves 3 to increase the heat exchange area; these spiral grooves 3 are a continuous spiral turbulence structure. One end of the first pipe 1 is connected to the external high-temperature water inlet pipe, providing a heat source for thermal energy regulation. The second pipe 2 is sleeved outside the first pipe 1 and connected to the external secondary network pipe, forming a closed secondary network medium circulation channel. Its two ends are connected to the secondary network return water pipe and the secondary network supply water pipe, respectively, for transporting the low-temperature medium to be heated. The nested structure greatly simplifies the structure of the heat inlet, shortens the medium transmission path, and reduces heat loss. Simultaneously, the spiral grooves 3 on the inner wall of the first pipe 1 are a continuous spiral turbulence structure. When the high-temperature medium flows within the first pipe 1, the spiral grooves 3 guide the medium along a spiral path, forcibly breaking the laminar flow state of the fluid and causing turbulence. This not only significantly increases the contact area between the medium and the pipe wall but also enhances the degree of fluid turbulence, significantly improving heat exchange efficiency.

[0023] A regulating component 4 for adjusting the hot water flow rate is installed in the middle of the first pipe 1, at the front end of the spiral groove 3. The regulating component 4 includes a rotatable valve core 41 installed inside the first pipe 1. The valve core 41 adjusts the flow rate of the high-temperature medium by changing the flow gap with the inner wall of the first pipe 1 through rotation. The valve core 41 in the regulating component 4 can rotate inside the first pipe 1, and by changing the flow gap with the inner wall of the first pipe 1 through rotation, the flow rate of the high-temperature medium entering the spiral groove 3 can be flexibly adjusted. When the parameters of the primary network and the secondary network change drastically, the valve core 41 can respond quickly. Combined with the efficient heat exchange of the spiral groove 3, the device can better adapt to fluctuations, improving the overall performance and adaptability of the thermal inlet heat energy regulation.

[0024] Preferably, a heat exchange chamber 5 is provided between the second pipe 2 and the first pipe 1. The two ends of the second pipe 2 are connected to the secondary network return water pipe and the secondary network supply water pipe, respectively. The heat exchange chamber 5 is located between the second pipe 2 and the first pipe 1, providing space for heat exchange between the secondary network medium and the high-temperature medium of the primary network. When the low-temperature medium in the secondary network return water pipe flows into the second pipe 2, it flows around the first pipe 1 in the heat exchange chamber 5, exchanging heat with the high-temperature medium in the first pipe 1 through the pipe wall, ensuring that the medium output from the secondary network supply water pipe reaches the expected temperature.

[0025] Furthermore, the depth of the spiral groove 3 gradually changes along the direction of medium flow, gradually deepening and then gradually shallowing from the inlet to the outlet of the first pipe 1. This design of the spiral groove 3 causes continuous changes in the velocity and flow regime of the high-temperature medium during flow. During the deepening stage, the medium velocity decreases, increasing the contact time with the pipe wall; during the shallowing stage, the velocity increases, the disturbance intensifies, and the turbulence effect is further enhanced. In this way, the spiral groove 3 can more efficiently utilize the heat of the high-temperature medium, improve the sufficiency of heat exchange, and effectively solve the problem of low heat exchange efficiency caused by laminar flow in traditional straight-tube heat exchangers.

[0026] Furthermore, an extension pipe 6 is installed through the bottom of the first pipe 1, and the extension pipe 6 passes through the bottom of the second pipe 2 and connects to the external primary network return water pipe. The extension pipe 6 is installed through the bottom of the first pipe 1 and passes through the bottom of the second pipe 2 to connect to the external primary network return water pipe, providing a return channel for the high-temperature medium of the primary network. After the high-temperature medium completes the heat exchange with the secondary network medium in the first pipe 1, it returns to the primary network return water pipe through the extension pipe 6, forming a complete primary network medium circulation.

[0027] It is worth noting that a temperature sensor 7 is installed on the inner wall of the extension pipe 6, and the temperature sensor 7 is electrically connected to the control module of the regulating component 4. The temperature sensor 7, located on the inner wall of the extension pipe 6 and electrically connected to the control module of the regulating component 4, monitors the primary network return water temperature in real time. Based on the data fed back by the temperature sensor 7, the control module controls the rotation angle of the valve core 41 in the regulating component 4, dynamically adjusting the flow rate of the high-temperature medium to ensure that the device maintains efficient and stable operation under different working conditions, achieving precise regulation of thermal energy.

[0028] Temperature sensor 7 can be a PT100 platinum resistance thermometer, with a measurement range of -50℃ to 200℃ and an accuracy of ±0.5℃. The wide measurement range of the PT100 platinum resistance thermometer completely covers this temperature range, and it has high stability and anti-interference ability at high temperatures, making it less prone to measurement deviations due to medium temperature fluctuations or pipeline vibrations. In addition, the high accuracy of ±0.5℃ can accurately capture subtle changes in return water temperature, providing real-time and reliable feedback data to the control module. This allows the module to dynamically adjust the valve core 41 opening according to the temperature difference, achieving precise closed-loop control of heat exchange efficiency.

[0029] Specifically, the regulating component 4 also includes a connecting block 42 disposed outside the first pipe 1, with a motor 43 for driving the valve stem 44 to rotate mounted on the upper part of the connecting block 42. The connecting block 42 provides mounting support for the motor 43 and the valve stem 44. The motor 43 is mounted on the upper part of the connecting block 42 and converts electrical energy into mechanical energy after being powered on, outputting rotational power. The valve stem 44 passes through the middle of the connecting block 42 and extends into the interior of the first pipe 1, with one end connected to the output shaft of the motor 43 and the other end installed through the valve core 41. When the motor 43 is working, it drives the valve stem 44 to rotate, thereby driving the valve core 41 to rotate inside the first pipe 1, realizing precise control of the rotation of the valve core 41 by the motor 43. It can quickly and accurately adjust the flow gap between the valve core 41 and the inner wall of the first pipe 1 according to system requirements, thereby controlling the flow rate of the high-temperature medium.

[0030] The motor 43 can be a servo motor with a response time of ≤0.5 seconds and a speed adjustment accuracy of ±1 rpm. This motor's response time ensures that upon detecting a parameter change, it quickly drives the valve core 41 to rotate via the valve stem 44, promptly adjusting the flow clearance. High-precision speed adjustment ensures a linear and precise correlation between the rotation angle of the valve core 41 and the flow rate adjustment, achieving stepless and stable control of the high-temperature medium flow rate and improving the device's adaptability and adjustment stability under complex operating conditions.

[0031] More specifically, the valve stem 44 extends through the middle of the connecting block 42 into the interior of the first pipe 1, and the valve core 41 is installed through the middle of the valve stem 44. The valve stem 44 serves to transmit power between the motor 43 and the valve core 41. One end is rigidly connected to the output shaft of the motor 43, transmitting the rotational power output by the motor 43; the other end is installed through the valve core 41, driving the valve core 41 to rotate synchronously within the first pipe 1. Simultaneously, a sealing structure between the valve stem 44 and the connecting block 42 prevents leakage of high-temperature media, ensuring the safety and reliability of the device's operation, enabling the regulating component 4 to work stably and efficiently, and guaranteeing the normal operation of the entire thermal energy regulating device.
