Abstract
The utility model discloses a liquid electric heater, which is invented to solve the problems of short service life, uneven heat conduction and the like of the conventional liquid electric heaters. The liquid electric heater comprises a cable conductor, a waterproof cover of the cable conductor, a waterproof rubber ring of the cable conductor, a waterproof upper cover, a waterproof seal ring, a protecting sleeve, a heat conduction pipe and an electrothermal element; the cable conductor sequentially passes through the waterproof cover of the cable conductor, the waterproof rubber ring of the cable conductor, the waterproof upper cover and the waterproof seal ring and is connected with the electrothermal element; the electrothermal element is accommodated in the heat conduction pipe; and the liquid electric heater further comprises insulating magnesium powder which is filled in the gap between the electrothermal element and the heat conduction pipe and other closed spaces/gaps of the heat conduction pipe. The liquid electric heater provided by the utility model has the advantages of good heat conductivity, long service life, environmental protection and energy conservation.
Description
Technical field
The utility model relates to a kind of heater, relates in particular to a kind of liquid electric heater.
Background technology
At present, the metal liquid electric heater that uses on the known market is provided with stratie by cable, cable the end of a thread, anti-head, circular metal heat pipe, heat pipe inside.Its working method is: heat pipe and heat pipe internal resistance heating element, transfer heat energy to by electric energy, and transmit heat pipe again and conduct heat, reach the purpose of liquid heating.But, at present the liquid electric heater subject matter of using have following some:
One, metal liquid electric heater stratie adopts porous ceramic to scurry resistance wire, because of porous ceramic production technology reason can't be fired longer size, resistance wire adopts in the stratie production process be import into after the requirement of spring-like the pottery back because of porous factor and more piece pottery scurry connect and produce easily in resistance wire form inhomogeneous, product quality is gone wrong
Two, because of the heat conduction of metal current electrical liquid heater heating process is to pass through the heat pipe heating liquid again after elder generation must be delivered to pottery in advance, transmittance process need pass through a plurality of steps, be not easy to energy-conservation, the heating element central temperature can't be passed to the outside fast and make heating element center gathering higher temperature when heating simultaneously, influences life of product.
Three insulating properties, because of adopting many empty potteries, existing heating element in heater, must arrange many skies to arrange many heater strips to seal in synchronously well in the useful space, because of want distance between the porous ceramic pitch-row very narrow that in narrow space between the positive and negative electrode apart from very narrow, therefore ceramic insulation generation electrode fusing problem and easily generation in the pyroprocess, and ceramic insulation instability, heatproof is not high, and it is poor that quality also has, and is easy to generate puncture.Good processing cost is also also difficult than high technology.
Four, water proofing property.What existing metal liquid electric heater heating seal adopted is epoxy sealing, but in the course of processing because of being easy to generate pore, and in the heating environment epoxy resin synchronously heat rise and change easy the water inlet.
The utility model content
The purpose of this utility model is to provide the liquid electric heater of a kind of good heat conduction effect, long service life, environmental protection and energy saving, has solved all inconvenience that existing electric heater brings to people because of problems such as heat transfer process complexity, insulation poor stabilities.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
A kind of liquid electric heater comprises cable, cable waterproof cover, cable waterproof apron, waterproof loam cake, waterproof grommet, protective sleeve, heat pipe and electric heating element; Described cable passes cable waterproof cover, cable waterproof apron, waterproof loam cake and waterproof grommet successively and links to each other with electric heating element; Described heat pipe is a hollow structure, and the heat pipe upper end embeds waterproof grommet and forms airtight; Described electric heating element is placed in the heat pipe; Described electric heating element is made up of instlated tubular, mica sheet and resistance heating wire, and wherein said mica sheet is wrapped in the instlated tubular outer surface, mica sheet outer surface uniform winding resistance heating wire;
Described liquid electric heater also includes insulation magnesium powder, and described insulation magnesium powder tamps space and other confined space spaces of heat pipe between electric heating element and the heat pipe.
Further, described heat pipe lower end employing argon fluorine welded seal.
Further, described electric heating element both ends is fixed by mica spacer.
The beneficial effect of liquid electric heater described in the utility model is: the electric heating element the selection of material of the utility model liquid electric heater and composition structure can be regulated as required, resistance heating wire directly heat conduction to the magnesium powder that insulate conducts to the heat pipe heating liquid again, a heat conduction link has been reduced by in the centre, thereby has further improved heat transfer efficiency; The heat pipe lower end makes the water resistance of this liquid electric heater more outstanding with argon fluorine welded seal; Electric heating element both ends fixedly makes the stability of this liquid electric heater and shake-proof ability better by mica spacer, and the liquid electric heater that comprehensive above-mentioned the utility model provides has really had the utilizability on the industry.
