Description

Technical Field

[0001] The utility model relates to the technical field of electric heaters, in particular to a heat sink for an electric heater and an electric heater. Background Art

[0002] Electric heaters can be widely used in mobile heating of residences, offices, hotels, shopping malls, hospitals, schools, train carriages, simple mobile houses and other civil and public buildings. They combine radiation and convection. The interior is a high-efficiency aluminum alloy heat dissipation wing panel with strong radiation capacity and large radiation area. It uses electric heating film as the heating material. Its ultra-large black crystal mirror appearance is fashionable, which fully meets the demanding requirements of people who pay attention to the beauty of room decoration. It mainly delivers heat by far-infrared radiation and thermal convection, and the negative ion function can refresh the air at all times.

[0003] At present, the existing electric heater heat sinks are usually stacked with equal spacing, and the spacing in the middle is fixed, so the heat dissipation effect is relatively fixed. When the indoor temperature is too high or too low and the heat dissipation effect needs to be adjusted, it can only be adjusted by controlling the heating temperature of the heating tube. Not only is the adjustment efficiency poor, but the energy consumption is also high and unstable. For this reason, we propose an electric heater heat sink and an electric heater. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a heat sink for an electric heater and an electric heater, which solve the problems raised in the above-mentioned background technology.

[0008] Preferably, the heating pipe runs through the interior of the two support plates.

[0009] Preferably, an insulating ring is provided on the outer side of the heating tube and at the connection portion with the support plate.

[0010] Preferably, a hole cooperating with the heating pipe is provided inside the sliding sleeve.

[0011] The utility model provides a heat sink for an electric heater and an electric heater, which have the following beneficial effects:

[0012] 1. The heat sink and the electric heater are coordinated through the sliding sleeve, the heat sink, the rotating shaft, the round rod, the sliding groove, the sliding rod, the slider, the transmission gear, the chain, the transmission groove and the adjusting knob. When it is necessary to adjust the spacing between several heat sinks to adjust the heat dissipation efficiency, it is only necessary to rotate the rotating shaft and the round rod through the positive and negative adjustment knob to drive several sliders to slide in the sliding groove, thereby driving several heat sinks to be evenly displaced and expanded or approached through the inclined setting characteristics of the sliding groove, and then the expanded area of ​​the heat sink can be adjusted according to the use requirements, and the adjusted heat dissipation area plays a role in adjusting the heat dissipation efficiency.

[0013] 2. The heat sink and the electric heater are matched with a limit gear, a mounting plate, a connecting rod, a latch, a stop plate, a spring, a groove and a pull plate. Its main function is to lock the limit gear through the latch after adjusting the spacing of the heat sink, thereby limiting the rotating shaft and the round rod to prevent the round rod from being accidentally touched or loosely rotated after the adjustment is completed, resulting in changes in the spacing of several heat sinks.
