Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary heating, in particular to a heater with adjustable electric heating tube for auxiliary heating. Background Art

[0002] At present, when a vehicle uses an air conditioner for heating operation in winter, at the initial stage of starting the vehicle engine, the heat generated by the engine cannot meet the temperature required inside the vehicle. In order to supplement this part of heat, it is necessary to add an auxiliary heat source, that is, an auxiliary electric heater, on the basis of the original heating equipment. The existing one has low thermal efficiency, resulting in poor overall heating effect. Under the relative energy consumption, its heating effect is poor, affecting the user experience.

[0003] A patent with a publication number of CN217817473U is disclosed in the prior art. Heat-conducting liquid is poured into the water-adding mechanism, and the heat-conducting liquid is discharged into the water container through the water-adding mechanism. The heat-conducting liquid is respectively discharged into the finned heat-dissipating tubes through the water container. When a user needs to keep warm, heat is generated by a special rare-earth electrothermal material heat source to heat the heat-conducting liquid in the finned heat-dissipating tubes. The heated heat-conducting liquid rises inside the finned heat-dissipating tubes, and the normal-temperature heat-conducting liquid in the finned heat-dissipating tubes flows to the periphery of the special rare-earth electrothermal material heat source, so that the heat-conducting liquid circulates repeatedly inside the finned heat-dissipating tubes. The heat of the heat-conducting liquid is conducted to the air outside the finned heat-dissipating tubes through the fins on the finned heat-dissipating tubes, and the exhaust device is turned on to blow the hot air into the vehicle, thereby improving the energy saving of the equipment, reducing the loss of heat, and prolonging the service life of the equipment; it includes a heating device and a water-adding mechanism.

[0004] With the use of the existing devices including the above patent, the deficiencies of this technology have gradually emerged, mainly manifested in the following aspects:

[0005] First, when the existing electric heater is in use, when it is necessary to adjust the outlet air temperature, the outlet air temperature is adjusted by adjusting the air volume of the fan and the temperature of the heating wire. This makes the output of the fan and the heating wire unstable due to frequent adjustment, affecting the service life of the fan and the heating wire.

[0006] Second, the existing electric heater is limited by its internal structure, resulting in the air entering the heater being unable to exchange heat with the heating structure under the influence of the internal structure and being quickly discharged, thereby reducing the efficiency of auxiliary heating.

[0007] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Utility Model

[0008] In view of the deficiencies in the prior art, the utility model solves the problem that in the traditional electric heater, due to the influence of the internal structure, the air entering the heater cannot exchange heat with the heating structure under the influence of the internal structure and is quickly discharged, thereby reducing the auxiliary heating efficiency.

The upper adjustment gear and the lower adjustment gear are respectively located on both sides of the regulating rod and are respectively engaged with the two regulating racks.

[0049] A first support seat 14 is fixedly connected in parallel on the outer wall of the installation housing 1. The first support seat 14 is provided with a hole body for avoiding the adjusting rod 12, and the adjusting rod 12 is slidably constrained in the hole body.

[0050] A first driving machine 15 is fixedly connected to the outer wall of the installation housing 1. The output end of the first driving machine 15 is engaged with the adjusting rack 13 through a gear.

[0051] Both ends of the electric heating tube 2 are rotatably installed on the opposite inner walls of the installation housing 1 by means of transverse tubes.

[0060] By adjusting the distance between the ends of the upper adjusting plate 4 and the lower adjusting plate 5 facing the electric heating tube 2, the range of the outgoing air can be adjusted. When rapid heating is required, the distance between the upper adjusting plate 4 and the lower adjusting plate 5 is reduced to concentrate the outgoing air, so that the blown air directly acts on the surface of the electric heating tube 2, increasing the contact area with the electric heating tube 2 and improving the heat exchange efficiency with the electric heating tube 2, enabling the air blown out of the installation housing 1 to be quickly heated;

[0061] Heat transfer fins 3 are arranged on the opposite peripheral walls of the electric heating tube 2. Rotating the electric heating tube 2 to make the heat transfer fins 3 vertically arranged realizes increasing the contact area with the blown air, further improving the heat exchange efficiency between the blown air and the electric heating tube 2, enabling the air blown out of the installation housing 1 to be quickly heated;

[0062] Among them, only by adjusting the distance between the upper adjusting plate 4 and the lower adjusting plate 5 or rotating the electric heating tube 2 can the temperature of the outgoing air be adjusted. Under the condition that the air source and the output of the electric heating tube 2 are constant, the adjustment of the temperature of the outgoing air is realized.
