Widely used liquid-filled electric heater in the background technology daily life (being commonly called as electric heating installation using oil as medium or electric oil-filled warmer) is electrothermal tube to be arranged on to the inside cavity of fin, filling heat-conductive oil around electrothermal tube.Conduction oil during this radiator work around electrothermal tube is heated, is raised to cavity top, along radiating tube or fin convection circulation, by the cavity wall surface, heat radiation is gone out, thereby heating outer space environment, be heated again around being dropped to electrothermal tube by air cooled conduction oil simultaneously, start new circulation; The advantage of this warmer is: conduction oil is taken away heat in inner loop, the fin surface temperature evenly, heat evenly, use comfortablely, can not send visible ray during use, without the electric operation noise; Simultaneously due to nothing blowing device, dustless during use, health; Free from extraneous odour.

This type of liquid-filled electric heater in the market mainly contains two species structures, a kind of is plate electric heater, the rectangular housing that the body of this electric heater is flat, its inner chamber is vacant electric heater and a conduction oil, heat by shell wall to distributing, the electric heater of this structure, processing technology is simple, reliable in structure, but described plate electric heater is to ensure enough area of dissipations, and its volume is often very large, not attractive in appearancely take up room again; Referring to Fig. 3, in order to increase area of dissipation, prior art also has a kind of multiple-piece electric heater 8, be generally that 9 to 11 fin form, every fin 81 is all the flat cavity of hollow, every a slice fin 81, all by two iron sheet punch formings, multi-disc fin 81 is arranged in order integrally weldedly, in electric heater when work,, conduction oil fills each fin again; This structure electric heater, processing technology is complicated, difficulty is large, and manufacturing cost is high, especially also has the potential safety hazard of leakage of oil.Simultaneously, also there is a common shortcoming in the oily spit of fland of described two kinds of structures, all only have exactly cavity and one group of heat generating component of a sealing because of electric heater, although product at least is provided with high and low two grades of heating and selects, but electric heater is when low-grade duty, and just heat generating component power reduces, but area of dissipation is still constant, thereby cause product fin surface temperature on the low side, use uncomfortable.

Utility model content the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and designs the liquid-filled electric heater of producing a kind of pair of fin, solves the shortcoming that prior art liquid-filled electric heater processing technology is complicated, can not keep the fin surface higher temperature when having the potential safety hazard such as leakage of oil and selecting low-grade work.

The utility model is to solve the problems of the technologies described above the technical scheme proposed to be: the liquid-filled electric heater of a kind of pair of fin comprises the radiator of two cavity structures; Described two radiators spacing is arranged are fixed on base, are equipped with heat generating component and conduction oil separately in this radiator; Described two groups of heat generating components electrically connect with the control circuit that is positioned at the radiator outside respectively.

Described two radiator tops are provided with the support that both are connected as one.

Between described two radiators, spacing is enough to guarantee cross-ventilation.

The bottom of described radiator be can accommodating described heat generating component heating clamber, the top of this heating clamber is the heat radiation wall of the flat that communicates with it.

Also coating the protection network of heat-conducting between described two radiators.

Compared with the existing technology, the new beneficial effect of this practicality is: radiator structure is simple, and processing technology is simple, and there is not leakage of oil hidden danger in dependable performance; This electric heater can select two groups of heating components to work individually or simultaneously, and heat radiation evenly; While particularly selecting low grade, only have one of them heating component adstante febre, the radiator surface temperature at its place the same while still working with two groups of heating components simultaneously, thereby guarantee the comfort level of using.
