Abstract
The invention relates to a finned-tube heater and production method thereof. A heating body is fitted in the heater housing and a power-supply connection terminal is fitted at the end part of the heater housing, insulation material is filled in the heater housing and insulation sealant is filled at the end port of the heater housing. The characteristic is that the external surface of the heater housing is fitted with finned-tube the lower part of which is buried in the heater housing. Advantages: raised surface area of the heater, low surface load and temperature, reduced heater housing size and raw material and cost and prolonged service life.
Description
Technical field
The invention belongs to the electric-heating technology field, particularly a kind of finned tube heater and production method thereof that directly electric energy is converted to heat energy.
Background technology
The conventional electric heating device is by metal tube, be arranged on heater in the metal tube, be arranged on the power supply terminal at metal tube two ends and the insulating material (as magnesia powder) that is filled in around the power supply terminal constitutes.Its manufacture method is: heater is fixed in the metal tube, recharges insulating material after drawing power supply terminal.During work, after the power supply terminal energized, the heater heating passes to outside the metal tube heat by magnesia powder.The electric heater of this structure is owing to very big to the limitation of metal tube diameter and length, so the big (10w/cm of heater surfaces load
2), the temperature height, the manufacturing cost height, useful life is short.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide that a kind of area load is little, temperature is low, heats is good, the finned tube heater and the production method thereof of low cost of manufacture, long service life.
The concrete technical solution of this finned tube heater is: at the heater housing internal fixation heater is arranged, be provided with power supply terminal in the heater housing end, in heater housing, be filled with insulating material, be filled with electric insulating sealant in the heater housing port, its special character is: be provided with finned tube on the heater housing surface, said finned tube bottom is embedded in the heater housing.
The degree of depth that above-mentioned finned tube heater, said finned tube are imbedded heater housing is 0.1-0.5mm, so that both contact-making surfaces are combined closely, combined together, improves heats.
The production method of this finned tube heater is: heater is fixed in the tubular metal heater housing, draw behind the power supply terminal fill insulant in heater housing again, make heater and heater housing secure fixation and insulation through the machine for shrinking draw, another metal tube is enclosed within on the heater housing, be rolled into finned tube through pipe mill, said finned tube height, a pitch of fins and sheet are thick can be regulated in advance according to heater surfaces power, and it is 0.1-0.5mm that finned tube is rolled into the heater housing degree of depth.
The production method of above-mentioned finned tube heater, said heater are nichrome or cermet or resistance wire.
The production method of above-mentioned finned tube heater, said insulating material are metal magnesium powder or insulating ceramics or heat-resisting high-temp glue.
Advantage of the present invention is that finned tube directly is rolled in the heater housing by pipe mill, makes both contact-making surfaces combine closely, combine together, and the heater table area increases greatly, and area load is little, temperature is low; Simultaneously can reduce heater housing diameter and length, save raw material greatly, manufacturing procedure is simple, has reduced manufacturing cost; Because finned tube height, a pitch of fins and sheet is thick can regulate arbitrarily according to heater surfaces power make area load to regulate arbitrarily, though reduced heater housing diameter and length, prolong the useful life of heater greatly.
