Description

Technical Field

[0001] This invention relates to the field of heating energy-saving technology, specifically to a heating energy-saving device. Background Technology

[0002] In existing heating systems, hot water is typically circulated through HVAC pipes for heat dissipation. However, traditional heating systems have the following problems: First, heat exchange efficiency is low, relying mainly on natural convection, resulting in uneven heat distribution; second, the waste heat of the hot water in the system is not fully utilized, leading to energy waste; and third, external electric power is required to drive auxiliary fans to enhance convection, increasing energy consumption.

[0003] Currently, some technologies have been developed to improve the energy efficiency of heating systems. For example, some systems add electric fans for forced convection, but this requires additional electricity; other systems use complex heat recovery devices, but these are costly and structurally complex, making them unsuitable for ordinary buildings.

[0004] CN223178922U discloses a heating device for HVAC engineering, relating to the field of heating equipment technology. Several heat flow boxes are arranged inside an outer protective frame, each with a wave-like shape. Several guide strips (first and second) are arranged inside the heat flow boxes. A protective water tank is located at the rear of the outer protective frame, and an auxiliary heating mechanism is located below the outer protective frame. The heat flow is in an S-shape through the guide strips, and the wave-like shape of the heat flow boxes greatly increases the contact area between the heat flow and the heat flow boxes, improving heating efficiency. The protective water tank effectively prevents the high temperature of the heat flow boxes from affecting the walls. Simultaneously, the temperature outside the heat flow boxes exchanges heat with the water in the protective water tank, raising the temperature of the water inside the protective water tank, facilitating subsequent household water use and achieving energy conservation. A heat exhaust fan in the auxiliary heating mechanism accelerates heat dissipation between the heat flow boxes, further improving heating efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a heating energy-saving device.

[0006] To solve the above problems, the technical solution of the present invention is: a heating energy-saving device, comprising:

[0007] A protective component, wherein a heating and ventilation pipe is provided inside the protective component, one end of the heating and ventilation pipe is a water inlet, and the other end is a water outlet;

[0008] The protective box is fixedly installed above the protective component;

[0009] A heat transmission assembly, three of which are connected to a protective assembly;

[0010] Fan housing, several of which are connected to the lower part of the protective assembly;

[0011] Fans, several of which are connected to a fan housing.

[0012] Furthermore, the protective component includes:

[0013] The outer casing has air inlets on both end faces of the outer casing;

[0014] A front cover plate, which is connected to the front side of the housing;

[0015] Air outlets, several of which are located on the lower end face of the outer casing;

[0016] Two through holes are located on the two end faces of the outer casing.

[0017] Furthermore, the heat transmission assembly includes:

[0018] Water box, which is fixedly connected to the rear end face inside the outer shell;

[0019] Small connecting pipes, two of the small connecting pipes are connected to the upper end of the water box, and the end of the small connecting pipe away from the water box is connected to the HVAC pipe;

[0020] Rotating wheel one, which is rotatably connected to the water box;

[0021] The shape memory alloy wire, with its lower end fitted onto a rotating wheel, utilizes the thermoelastic phase transformation properties of the shape memory alloy to convert thermal energy into mechanical energy. The shape memory alloy wire is preferably made of nickel-titanium alloy, which undergoes a martensitic-to-austenitic phase transformation in hot water at 40℃-60℃, generating approximately 4-8% shrinkage strain. This deformation is converted into torque under the constraint of the rotating wheel system, driving the wheel to rotate. As the shape memory alloy wire circulates between the hot water zone and the air zone, it continuously undergoes the phase transformation process of heating contraction and cooling recovery, forming continuous rotational motion.

[0022] Rotary wheel two, which is located above rotary wheel one, and the shape memory alloy wire is sleeved on rotary wheel two;

[0023] A fixed shaft is fixedly connected to the rear end of the second rotating wheel;

[0024] A fixing plate, wherein a fixing shaft is rotatably connected to the front upper end of the fixing plate.

[0025] Furthermore, the fan includes:

[0026] A small motor is fixedly connected to the rear end face inside the fan housing;

[0027] A rotating shaft, which is fixedly connected to the drive end of a small motor;

[0028] The fan blades are fixedly connected to the end face of the rotating shaft away from the small motor, and heat dissipation is enhanced through forced convection.

[0029] Furthermore, a through groove is formed on the upper end face of the fan housing.

[0030] Furthermore, the protective box is equipped with an energy storage device, which can store mechanical energy and convert it into electrical energy to provide auxiliary power for the fan, achieving energy self-sufficiency. The protective components are designed with optimal airflow path in mind. Cold air enters from the air inlets on both sides, is heated by the HVAC pipes, and is discharged from the air outlet at the bottom, forming a highly efficient heat exchange cycle.

[0031] Furthermore, a mounting plate is fixedly connected to the rear end face of the outer casing.

[0032] The advantages of this invention compared to existing technologies are:

[0033] The advantages of this invention lie in its thermal energy transmission component, which utilizes the thermoelastic phase change characteristics of shape memory alloys to directly convert waste heat from the heating system into mechanical energy to drive the cooling fan, reducing external power consumption. Through the thermal-mechanical energy conversion mechanism, energy self-circulation is achieved. The fan operation requires little or no external power input, reducing operating costs. At the same time, the phase change temperature of the shape memory alloy can be precisely set, and the fan automatically starts when the heating water temperature reaches a specific value, achieving intelligent temperature control and avoiding overheating or energy waste. Forced convection significantly improves heat exchange efficiency, resulting in a more uniform temperature distribution and improved comfort. Attached Figure Description

[0042] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0043] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0044] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] like Figures 1 to 7 As shown, the technical solution of the present invention is as follows: a heating energy-saving device, comprising: a protective component 1, a heating and ventilation pipe 2, a protective box 3, a heat transmission component 4, a mounting plate 5, a fan shell 6, and a fan 7. The protective component 1 consists of an outer shell 101, a front cover plate 103, an air inlet 102, an air outlet 104, and a through hole 105. The outer shell 101 is preferably made of aluminum alloy, and its internal space is used to accommodate the heating and ventilation pipe 2 and the heat transmission component 4. The front cover plate 103 is connected by a snap-fit, which facilitates opening for internal cleaning and maintenance. A dustproof frame is fixedly connected to the air inlet 102 to prevent dust from entering the interior of the outer shell 101.

[0046] The HVAC pipe 2 is made of stainless steel and is arranged inside the outer casing 101 to maximize the heat dissipation area. Its inlet 201 and outlet 202 are connected to the supply and return water pipes of the heating system, respectively. The protective box 3 is installed on the top of the outer casing 101 and contains an energy storage device and control circuit for energy storage and distribution. The fan housing 6 and the fan 7 are installed on the bottom of the outer casing 101.

[0047] like Figures 1 to 7As shown, the HVAC pipe 2 is made of stainless steel and is arranged inside the outer casing 101 to maximize the heat dissipation area. Its inlet 201 and outlet 202 are connected to the supply and return water pipes of the heating system, respectively. The protective box 3 is installed on the top of the outer casing 101 and contains an energy storage device and control circuit for energy storage and distribution. The fan housing 6 and the fan 7 are installed on the bottom of the outer casing 101.

[0048] The shaft of the rotor 403 is connected to a small generator 8 via a coupling, converting rotational mechanical energy into electrical energy. The generated electrical energy is input into an energy storage device inside the protective box 3 for storage. The device can be equipped with multiple thermal energy transmission components 4, each component connected to an independent generator 8, or jointly driving the same generator 8 through a transmission mechanism. After the generated electrical energy is integrated by the energy storage device, it is distributed to each fan 7 as needed by the control circuit.

[0049] like Figures 1 to 7 As shown, the fan 7 includes a small motor 701, a shaft 702, and fan blades 703. The small motor 701 is a DC brushless motor with a power of 10-20W, fixed inside the fan housing 6, and powered by the energy storage device in the protective box 3. Through the above-mentioned energy conversion and distribution mechanism, multiple heat transmission components 4 can work together to drive several fans 7.

[0050] In practical use, hot water flows into the HVAC pipe 2 from the inlet 201. Part of the heat is dissipated through the pipe wall, while the remaining hot water is diverted to the water box 401 via the small connecting pipe 402. The hot water heats the shape memory alloy wire 404, causing it to periodically contract and expand, driving the shaft of the second rotor 405 to rotate continuously. Mechanical energy is transferred to the generator 8 through the shaft of the first rotor 403, converted into electrical energy, and stored in the energy storage device of the protective box 3, thereby powering the small motors 701 of each fan 7. After the fan 7 starts running, it generates airflow. Cold air enters through the air inlet 102, is heated by the HVAC pipe 2, and is discharged from the air outlet 104, forming a forced convection circulation. When the heating water temperature is high, the phase change rate of the shape memory alloy accelerates, the shaft speed increases, the power generation increases, the fan airflow increases accordingly, and the heat dissipation is enhanced; when the water temperature decreases, the airflow automatically decreases, thereby achieving self-regulating operation and maintaining a stable indoor temperature.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
