heater

Abstract

The invention relates to a heater, which comprises a heat sink and heating elements arranged in the heat sink. The heat sink comprises at least one transversely-arranged accommodating cavity and a plurality of heat dissipation cavities which are used for air convection from bottom to top and arranged longitudinally; the heating elements are transversely arranged in the accommodating cavity and pass through the heat dissipation cavities; the heater is characterized in that: the heat dissipation cavities at least comprise a first heat dissipation cavity and a second dissipation cavity from bottom to top; and correspondingly, the heating elements at least comprise a first heating element passing through the first heat dissipation cavity and a second heating element passing through the second heat dissipation cavity. Compared with the prior art, the invention has the advantages that: the heat dissipation and heating effects are fulfilled by adopting a mode of air convection from bottom to top, and the heater is low in energy consumption and low in hot air outlet temperature, and does not need an air blower for assistance, avoids scalding of human body, and is simple in overall structure, convenient and fast to assemble and easy to produce.

Description

technical field [0001] The invention relates to a heater. Background technique [0002] Most common heaters dissipate heat in the form of thermal radiation, such as the Chinese utility model patent "Energy-saving Electric Heater" (authorized announcement number: CN201059678Y) with the patent number ZL200720052171.4, and the Chinese invention patent application publication with the application number 200910119205.0 "A Multifunctional Electric Heater" (publication number: CN101509679A), this type of heater generally includes a shell, a heating element, and a launch plate in structure, and the heat consumption is relatively large, and the temperature of the heater itself is relatively high, so it is easy to burn , It is also easy to cause other combustibles around to burn, so it is easy to cause accidents without paying attention, and there are certain safety hazards. If it is necessary to increase the convection effect, it is generally necessary to set up a fan to blow it, wh...

[0002] Most common heaters dissipate heat in the form of thermal radiation, such as the Chinese utility model patent "Energy-saving Electric Heater" (authorized announcement number: CN201059678Y) with the patent number ZL200720052171.4, and the Chinese invention patent application publication with the application number 200910119205.0 "A Multifunctional Electric Heater" (publication number: CN101509679A), this type of heater generally includes a shell, a heating element, and a launch plate in structure, and the heat consumption is relatively large, and the temperature of the heater itself is relatively high, so it is easy to burn , It is also easy to cause other combustibles to burn around, so it is easy to cause accidents without paying attention, and there are certain safety hazards

If you need to increase the convection effect, you generally need to set up a fan to blow it, which will inevitably increase energy consumption. At the same time, the fan blowing can only achieve heating in some areas, and the effect is not good

[0003] As improvement, a kind of heater is arranged in the prior art, see Figure 5 and Image 6 As shown, the heater includes a heat sink 1a and a heat generating body disposed in the heat sink 1a. The heat sink 1a has a plurality of horizontally arranged accommodating chambers 11a and a plurality of longitudinally arranged heat dissipation chambers for air convection from bottom to top. 2a, the heating element is arranged horizontally in the accommodating cavity 11a and runs through the cooling cavity 2a. This type of heater utilizes the chimney effect to greatly improve the convection effect, but this type of heater has the following disadvantages: only the top is provided with a hot air outlet, Therefore, the top is hot, and it is easy to burn if you are not careful; secondly, because the heat outlet is set higher, the human body will feel the heat after the temperature of the whole room rises, so the heating is slow and consumes a lot of energy
