Description

Technical Field

[0001] This invention relates to heating equipment, specifically a three-dimensional windless convection heater. Background Technology

[0002] As living standards improve, more and more people are choosing to install heating equipment in their homes to get through the cold winter. Air source heat pump heating equipment offers excellent comfort and convenience.

[0003] Chinese utility model patent CN210267488U discloses an air source heat pump heating device, comprising: a compressor having an air inlet and an exhaust outlet; an outdoor heat exchanger having a first outdoor heat exchanger port and a second outdoor heat exchanger port, the second outdoor heat exchanger port being connected to the air inlet; and an indoor heat exchanger comprising: an evaporator having a closed evaporation chamber; a condenser having a closed condensation chamber; a connecting pipe connecting the evaporator and the condenser; and a refrigerant channel disposed in the evaporator chamber and having a refrigerant inlet pipe and a refrigerant outlet pipe, the refrigerant inlet pipe being connected to the exhaust outlet and the refrigerant outlet pipe being connected to the first outdoor heat exchanger port. This air source heat pump heating device combines latent heat exchange with sensible heat release, significantly improving heat exchange efficiency compared to sensible heat exchange alone. The condensed phase change medium liquefies and returns to the evaporator chamber, continuing to absorb heat and vaporize, thus circulating between the evaporator and condenser chambers without the need for an external circulation pump to drive the phase change medium circulation.

[0004] Chinese invention patent CN113237130B discloses a high-efficiency solar-air-source circulating heating system, comprising a solar collector system, a hot water storage tank, an air-source heat pump, and heating terminals. The solar collector system is connected to a heating inlet pipe and a heating outlet pipe. The heating inlet pipe is connected to the outlet of the heating terminal, and the heating outlet pipe is connected to the inlet of the heating terminal. An electric three-way valve I, a circulation pump I, and an electric three-way valve II are respectively installed along the water flow direction on the heating outlet pipe. The hot water storage tank has an inner tank, which is connected to the air-source heat pump through a heat pump circulation pipe. An electric three-way valve IV is installed on the heating inlet pipe between the electric three-way valve III and the solar collector system. This system controls the circulation direction of the pipes through four electric three-way valves, enabling the system to achieve five functional circulation modes. This maximizes the utilization of solar energy, ensures the highest COP of the air-source heat pump, saves energy, and guarantees heating effect.

[0005] As can be seen from the above, air source heat pump heating technology has seen a flourishing of diverse applications in my country. However, most existing air source heat pump heating equipment focuses on energy efficiency and performance. While the heating terminals come in various forms, they often suffer from drawbacks such as monotonous appearance, complex installation, and the need to damage wall-mounted brackets to install heating radiators, thus affecting the aesthetics of home decoration. Summary of the Invention

[0006] To address the problems mentioned in the background technology, this solution provides a three-dimensional windless convection heater to solve the problems of inconvenient installation and monotonous appearance of traditional radiators.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: a three-dimensional windless convection heater, including an inlet pipe, an outlet pipe, a top cover, a base, and several heat exchange tubes. The top cover is equipped with a water collection pipe, which has several water inlets corresponding to each of the heat exchange tubes. The upper ends of all the heat exchange tubes are connected to the water inlets, and the outlet of the water collection pipe is connected to the outlet pipe. The base is equipped with a water distribution pipe, which has several water inlets corresponding to each of the heat exchange tubes. The lower ends of all the heat exchange tubes are connected to the water inlets, and the outlet of the water distribution pipe is connected to the inlet pipe. This heater, as an indoor terminal of a heating system, is easy to install, requires no wall damage, and has a three-dimensional and aesthetically pleasing appearance.

[0008] Furthermore, for the overall aesthetics and stability of the heater, the water collection pipe is installed inside the top cover, and the lower end face of the top cover is provided with a first mounting hole corresponding to each of the heat exchange pipes. The upper end of the heat exchange pipe passes through the first mounting hole and connects to the water collection port. The water distribution pipe is installed inside the base, and the upper end face of the base is provided with a second mounting hole corresponding to each of the heat exchange pipes. The lower end of the heat exchange pipe passes through the second mounting hole and connects to the water distribution port.

[0009] Furthermore, in order to make the product's appearance neater and more aesthetically pleasing, and to facilitate product installation, the base is provided with a water inlet and a water outlet. The water inlet pipe is connected to the water inlet, and the water outlet pipe is placed in the middle of all the heat exchange tubes. The upper end of the water outlet pipe extends into the top cover and is connected to the water collection pipe, and the lower end of the water outlet pipe extends into the base and is connected to the water outlet.

[0010] Furthermore, both the water collection pipe and the water distribution pipe are circular or elliptical, and all the water collection ports and water distribution ports are evenly spaced on the water collection pipe and the water distribution pipe.

[0011] Furthermore, all the heat exchange tubes are inclined in the same direction, either clockwise or counterclockwise, with an inclination angle preferably between 30° and 50°. This creates a perforated, diagonally patterned tube body, resulting in a unique appearance. The tilted and twisted shape also increases the distance the heat source travels within the tube, while simultaneously enhancing the rigidity of the heat exchange tubes and the overall structure. Additionally, all the heat exchange tubes have an inwardly concave and twisted arc shape in the center, which also increases the distance the heat source travels within the tube and makes the product's shape more varied and aesthetically pleasing.

[0012] Furthermore, a fan is installed inside the base, and the base is also provided with an air inlet and several air outlets. The air outlets are aligned with the heat exchange tubes, and the air inlet can be located on the side wall or bottom of the base depending on the configuration of the fan. Preferably, the fan is a vortex centrifugal fan, which has advantages such as low loss, high efficiency, and low noise.

[0013] Furthermore, the base has several support legs installed at its bottom, and the air inlet is located at the bottom of the base. To create a draftless convection effect, the upper surface of the base has a circular recess, on which all the second mounting holes are arranged. The recess has an inclined surface around its perimeter, at an angle of 20° to 60° to the horizontal. All the air outlets are evenly distributed on this inclined surface. This arrangement of circumferentially distributed air outlets, aligned with the heat exchange tubes in the recess, creates three-dimensional disturbance in the air surrounding the heat exchange tubes, enhancing the convective heat transfer effect.

[0014] The beneficial effects of this invention are as follows: This three-dimensional, windless convection heater, as the terminal unit of an air-source heat pump heating system, is easy to install and aesthetically pleasing. It is floor-standing and easy to install indoors, requiring no damage to walls or decorations. It is simply connected to the air-source heat pump heater via pipes. The heat source of the air-source heat pump heater (usually water, but hot air can also be used) is pumped into the inlet pipe of the three-dimensional, windless convection heater indoors. The heat is then evenly distributed to each heat exchanger tube through a stainless steel main pipe, and heat is evenly distributed from bottom to top within the heat exchanger tubes. A vortex centrifugal fan agitates the air around the heat exchanger tubes, creating airflow and maximizing the release of heat into the air, forming natural convection heat exchange. The hot water after heat exchange is collected from the top water collection pipe and flows back to the outdoor air-source heat pump heater for reheating, thus forming a complete heat absorption-release process. Through continuous circulation, a comfortable indoor temperature is achieved. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings. It is worth noting that these specific embodiments are merely representative specific embodiments of the present invention, and the specific methods, apparatuses, conditions, materials, etc., exemplified therein are not intended to limit the present invention or the corresponding specific embodiments.

[0020] Three-dimensional windless convection heater, such as Figures 1-4 As shown, the system includes an inlet pipe 11, an outlet pipe 12, a top cover 2, a base 1, and several heat exchange pipes 13. The top cover 2 is equipped with a water collection pipe 14, which has several water collection ports corresponding to each of the heat exchange pipes 13. The upper ends of all the heat exchange pipes 13 are connected to the water collection ports, and the outlet of the water collection pipe 14 is connected to the outlet pipe 12. The base 1 is equipped with a water distribution pipe 15, which has several water distribution ports corresponding to each of the heat exchange pipes 13. The lower ends of all the heat exchange pipes 13 are connected to the water distribution ports, and the outlet of the water distribution pipe 15 is connected to the inlet pipe 11. In this embodiment, for the sake of the overall aesthetics and stability of the heater, the water collection pipe 14 is installed inside the top cover 2. The lower end face of the top cover 2 is provided with a first mounting hole corresponding to each of the heat exchange pipes 13. The upper end of the heat exchange pipe 13 passes through the first mounting hole and connects to the water collection port. The water distribution pipe 15 is installed inside the base 1. The upper end face of the base 1 is provided with a second mounting hole corresponding to each of the heat exchange pipes 13. The lower end of the heat exchange pipe 13 passes through the second mounting hole and connects to the water distribution port.

[0021] Furthermore, in order to make the product's appearance neater and more aesthetically pleasing, and to facilitate product installation, the base 1 is provided with a water inlet and a water outlet. The water inlet pipe 11 is connected to the water inlet, and the water outlet pipe 12 is placed in the middle of all the heat exchange pipes 13. The upper end of the water outlet pipe 12 extends into the top cover 2 and is connected to the water collection pipe 14, and the lower end of the water outlet pipe 12 extends into the base 1 and is connected to the water outlet.

[0022] Furthermore, both the water collection pipe 14 and the water distribution pipe 15 are non-closed circular or elliptical rings, and all the water collection ports and water distribution ports are evenly spaced on the water collection pipe 14 and the water distribution pipe 15 to ensure uniform flow of the heat source.

[0023] Furthermore, the inlet pipe 11, outlet pipe 12, heat exchange pipe 13, water collection pipe 14, and water distribution pipe 15 can be made of stainless steel pipes, which are durable and have a stylish and beautiful appearance.

[0024] Furthermore, all the heat exchange tubes 13 are inclined in the same direction, either clockwise or counterclockwise, with an inclination angle preferably between 30° and 50°. This creates a perforated tube body with a diagonal pattern, resulting in a unique appearance. The tilted and twisted shape of the heat exchange tubes 13 also increases the distance the heat source travels within the tube, while simultaneously enhancing the rigidity of the heat exchange tubes 13 and the overall structure. Additionally, all the heat exchange tubes 13 are curved and concave in the middle, forming a tube body that narrows in the middle. This also increases the distance the heat source travels within the tube and makes the product's shape more varied and aesthetically pleasing.

[0025] Furthermore, a fan 3 is installed inside the base 1, and the base 1 is also provided with an air inlet 100 and several air outlets. The air outlets are aligned with the heat exchange tube 13, and the air inlet can be opened on the side wall or bottom of the base 1 depending on the configuration of the fan 3. Preferably, the fan 3 is a vortex centrifugal fan, which has the advantages of low loss, high efficiency, and low noise.

[0026] Furthermore, in this embodiment, in order to make the structure more scientific, a number of support legs are installed at the bottom of the base 1, and air gaps are formed between the support legs. The fan 3 is installed in the middle of the bottom plate of the base 1, and the air inlet 100 is located in the middle of the bottom plate of the base 1 to facilitate air intake. To achieve windless convection, the air outlet includes a first air outlet 101 and a second air outlet 102. The upper surface of the base 1 has a circular or elliptical recess. All the second mounting holes are evenly arranged circumferentially on the recess. The periphery of the recess has an inclined surface at an angle of 20° to 60° with the horizontal plane. All the first air outlets 101 are evenly spaced on the inclined surface. Thus, the circumferentially distributed first air outlets 101 are directly aligned with the heat exchange tube 13 on the recess, generating three-dimensional disturbance to the air around the heat exchange tube 13 and enhancing the convective heat transfer effect. The second air outlets 102 are located on the recess and between the second mounting holes and the inclined surface (i.e., at the edge of the recess). All the second air outlets 102 are vertically arranged, disturbing the air from bottom to top and helping the hot air to disperse more quickly.

[0027] Furthermore, the first air outlet 101 and the second air outlet 102 are staggered.

[0028] This designed heater serves as the indoor terminal of the heating system, offering convenient installation without requiring wall damage and boasting an aesthetically pleasing three-dimensional design. It is a floor-standing unit installed indoors, connected to an air-source heat pump heater via piping. The heat source from the air-source heat pump heater is pumped to the inlet pipe 11 of the indoor three-dimensional, windless convection heater, and then evenly distributed to each heat exchanger tube 13 via the stainless steel main pipe's branch pipes 15. Within the heat exchanger tubes 13, heat is evenly distributed from bottom to top. A vortex centrifugal fan 3 agitates the air around the heat exchanger tubes 13, creating airflow and maximizing the release of heat into the air, forming natural convection heat exchange. The hot water after heat exchange is collected from the top collecting pipe 14 and returned to the outdoor air-source heat pump heater for reheating, thus forming a complete heat absorption-release process. Through continuous circulation, a comfortable indoor temperature is achieved.

[0029] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention shall still fall within the scope of the patent of the present invention.
