[0001] The present invention relates to the technical field of heating equipment, and in particular to a heating terminal. Background Art

[0002] Half of my country's regions experience temperatures below zero for long periods of time in winter, requiring indoor heating to ensure normal living. Cities usually use centralized heating, but this method relies on coal combustion to heat boilers, polluting the air. In addition, new rural areas are not suitable for access to centralized heating networks, so some areas use heating terminals with electric heating pipes for heating. However, traditional electric heating pipes have low effective electric-to-heat conversion efficiency, are heavy, and are inconvenient to use. They also have slow temperature rises and are uncontrollable, making them prone to fires and other serious consequences. Summary of the Invention

The wind curtain slits are arranged horizontally, and the wind curtain slits form an angle of 10-20° with the side wall of the upper air outlet cover, and are inclined downward. The optimal angle is 15°. The wind curtain slits are the air outlets of the cross-flow fan, and a convection outlet is provided on the top of the upper air outlet cover.

[0006] Specifically, a damper is installed at the convection air outlet, and the damper is driven by a damper servo motor.

[0007] Specifically, the heating plate unit is a nano-ceramic glass heating plate with a length of 400 mm, a width of 150 mm, and a thickness of 8 mm.

[0008] Specifically, mounting side ears are respectively provided on both sides of the heating plate fixing frame, and through holes are provided on the mounting side ears. The heating plate fixing frame is fixed to the inner side of the frame shell by bolts. Guide grooves are provided on the inner sides of both sides of the heating plate fixing frame, and the heating plate unit is inserted into the guide grooves. A plurality of fixing holes are provided on the heating plate fixing frame, and fixing bolts are assembled in the fixing holes to fix the heating plate unit in the guide groove of the heating plate fixing frame. The spacing between two adjacent heating plate units is 65 mm.

[0009] Specifically, the isolation plate is made of a corrugated aluminum plate with a thickness of 1.5-2 mm.

[0010] Specifically, an air inlet is provided at the bottom of the rack shell.

[0011] Specifically, a wiring terminal is provided on one side of the heating plate unit, and a wire is connected to the wiring terminal and then connected to the controller.

[0012] Specifically, there is a certain distance between the heating plate unit and the heat conduction heating plate and the protective grille.

The controller is also respectively connected to the damper adjustment servo motor and the cross-flow fan.

[0013] Specifically, the controller is connected to the laser gyroscope and the indoor WIFI transmitter respectively. The indoor WIFI transmitter is connected to the indoor WIFI router to achieve networking and is used to connect to the remote control.

The temperature of the heating plate surface can be quickly heated from room temperature to above 450°C within 120 seconds, which is comparable to traditional electric heating. Compared with the traditional heating tube, the heating efficiency is improved by 2-3 times; the heating body adopts nano-microcrystalline glass heating plates to form a longitudinal deheating array, and uses the "Brown effect" generated by the alternating electric field of nano-energy-saving materials in the thermal organization, as well as the mutual collision between carbon atoms and molecular clusters. The friction instantly converts electrical energy into thermal energy, which is a high-energy particle straight-through heating. The heat is dissipated in the form of infrared radiation with a wavelength of 4-18 microns. The effective electrothermal conversion rate is more than 99.6% (the thermoelectric conversion efficiency of conventional nickel-chromium alloy heating wire is 50%). The radial current inside the polymer infrared radiation material is extremely small due to electric field heating, ensuring fast energy consumption and long service life when safe. The designed service life can reach 25,000 hours. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] like Figure 1-9 The heating terminal shown includes a rack shell 6, a left rack guard 4, a right rack guard 10, and an upper air outlet cover 1. Universal wheel support frames are respectively installed on both sides of the bottom of the rack shell, and at least two universal wheels are installed under the universal wheel support frames. A heating plate fixing frame 7 is provided in the middle of the rack shell 6, and a plurality of heating plate monomers 9 are fixedly installed in the heating plate fixing frame 7. An isolation plate 8 is provided between two adjacent heating plate monomers 9. A protective grille 11 is installed on the front side of the rack shell 6, and a heat conduction heating plate 3 is installed on the rear side of the rack shell 6. A cross-flow fan 2 is installed on the upper end of the rack shell 6, a left rack guard 4 is installed on the left side of the rack shell 6, and a right rack guard 10 is installed on the right side of the rack shell 6. The upper end of the rack shell 6 is buckled with the upper air outlet cover 1.

[0028] Specifically, a plurality of wind curtain slit openings 101 are provided on the side of the upper air outlet cover 1 on the same side as the protective grid 11. The wind curtain slit openings 101 are arranged horizontally. The wind curtain slit openings 101 form an angle of 10-20° with the side wall of the upper air outlet cover 1 and are inclined downward. The optimal angle is 15°. The wind curtain slit openings 101 are the air outlets of the cross-flow fan, which generate a shielding air curtain. A convection outlet 102 is provided on the top of the upper air outlet cover 1 to discharge the air heated by the thermosiphon.

[0029] Specifically, a damper is installed at the convection air outlet 102 , and the damper is driven by a damper servo motor.

[0030] Specifically, the heating plate unit 9 is a nano-ceramic glass heating plate with a length of 400 mm, a width of 150 mm, and a thickness of 8 mm.

[0031] Specifically, mounting side ears 71 are respectively provided on both sides of the heating plate fixing frame 7, and through holes are provided on the mounting side ears 71. The heating plate fixing frame 7 is fixed to the inner side of the frame shell 6 by bolts. Guide grooves 72 are provided on the inner sides of the two side edges of the heating plate fixing frame 7, and the heating plate unit 9 is inserted into the guide grooves 72. A plurality of fixing holes are provided on the heating plate fixing frame 7, and fixing bolts 73 are assembled in the fixing holes to fix the heating plate unit 9 in the guide grooves 72 of the heating plate fixing frame 7. The spacing between two adjacent heating plate units 9 is 65 mm.

[0032] Specifically, the isolation plate 8 is made of a corrugated aluminum plate with a thickness of 1.5-2 mm. The isolation plate 8 can not only buffer thermal deformation, but also compensate for the temperature of the heating space before and after the heating plate unit 9.

[0033] Specifically, an air inlet 61 is provided at the bottom of the frame housing 6 .

[0034] Specifically, a terminal block is provided on one side of the heating plate unit 9. After connecting, the wires are connected on the same side, eliminating the need for cluttered wiring and ensuring smooth thermosiphoning. This significantly improves insulation quality, allowing the unit to withstand 25°C cold water spray directly onto the heating plate unit 9 without cracking. It features four heating modes: Intelligent Rapid Heating Mode: forced spiral airflow with continuously variable speed adjustment; Natural Heat Exchange Mode: natural convection airflow for a longer heating time, allowing the thermal storage plate to partially store energy; Energy Storage and Heat Storage Mode: closing the cyclone outlet to prevent convection, allowing the thermal storage plate to fully store energy; and Hybrid Heat Exchange Mode: connecting to an outdoor photovoltaic heat source and a superconducting dielectric tube for low-energy hybrid heating. This is achieved through intermittent power supply to the heating plate and controlled by an intelligent temperature control unit. This improves thermoelectric conversion efficiency, saving 30-35% in overall electricity compared to resistance heating mode.

[0035] Specifically, there is a certain distance between the heating plate monomer 9 and the heat conduction heating plate 3 and the protective grille 11. The front and rear of the heating plate monomer 9 constitute a relatively independent heating space. The air entering from the air inlet 61 at the bottom of the rack shell 6 is gradually heated by the heating plate monomer 9 during the rising process. The terminal of the heating plate monomer 9 is connected to the controller 12 through a wire 13. The controller 12 is assembled on the left rack guard 4 or the right rack guard 10, and the control panel is exposed to the outside. The controller 12 is respectively connected to three K-type thermocouples 14, 15, and 16. The controller is also respectively connected to the damper adjustment servo motor and the cross-flow fan.

[0036] Specifically, the controller 12 is connected to the laser gyroscope 19 and the indoor WIFI transmitter 21 respectively. The laser gyroscope 19 controls the overturning power off, and the indoor WIFI transmitter 21 is connected to the indoor WIFI router 20 to achieve networking and is used to connect to the remote control 22.

[0037] Specifically, the number of the heating plate monomers 9 is set to 3 or 4, wherein the 3-piece machine is suitable for heating an area of ​​25m 2 , floor height 2.5-2.7m, 4-piece machine is suitable for heating area 32㎡, floor height 2.5-2.7m.

[0038] Its working principle is:

[0039] The heating terminal has a size of 680×120×1080mm (L×W×H) and a net weight of 25kg. It is easy to install and carry and can be placed anywhere indoors. It can be wall-mounted or floor-standing. It does not require any connecting pipes and can be used by connecting to 220VAC mains power.

[0040] The maximum power is 2400-3200W, the rated power is 1440-1920W, and when the heat load efficiency generated is equivalent to the heat load of the resistance heating tube, the power consumption is only 65% ​​of the resistance heating. The heat load is released to the heating space in three ways: radiation, convection and conduction. It is controlled by the preset intelligent temperature control unit in the controller and adopts intermittent heating linkage energy-saving operation mode. The heating unit 9 adopts 400×150×8mm nano-microcrystalline glass heating plate to form a longitudinal heat dissipation array. After 6s of power-on, the surface temperature is ≥70℃. After 180-300s of power-on, the surface temperature can reach ≥350℃. When the surface temperature reaches the preset heat load peak temperature, it can enter the logical intermittent power supply mode; the nano-microcrystalline glass heating plate is powered off for 40s and then powered on for 60s, and the cycle is repeated. During the 40-second power-off heat release cycle, the infrared radiation attenuation and temperature attenuation of the heating plate are both ≤15%. During the 60-second power-on heat storage cycle, the heating plate unit 9 only needs 20-30 seconds to reach peak infrared radiation and heat load. The terminal temperature of the convection and conduction heating modes meets the national standards, and the terminal temperature is ≤100-110°C. The infrared radiation mode can directly heat non-white objects at a distance of ≤3.5m from the terminal, but there is an obvious burning sensation at a distance of ≤0.5-0.8m. Care should be taken to prevent overheating and long-term direct drying and dehydration.

Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
