The electric heater comprises an aluminum profile cooling block (1) and a cast aluminum electric heater (2); the center of the aluminum profile cooling block (1) is provided with a through hole (11), and the outer edge thereof is provided with two horizontal ribs (12); the horizontal ribs (12) are symmetrically arranged on the left side and the right side of the outer edge of the aluminum profile cooling block (1); the two horizontal ribs (12) are respectively provided with a plurality first tooth slices (13); the first tooth slices (13) are divided into two rows; the two rows of the first tooth slices (13) are symmetrically deployed on the front side and the rear side of the horizontal ribs (12) and are vertical to the horizontal ribs (12); and the outer edge of the aluminum profile cooling block (1) is also provided with two second tooth slices (14), the two second tooth slices (14) are symmetrically deployed in the middle of the outer edge of the aluminum profile cooling block (1) back and forth and are in parallel with the first tooth slices (13), and the aluminum profile cooling block (1) is sleeved on the cast aluminum electric heater (2). The meter box electric heater with quick heat transfer is characterized by small size, uniform cooling, quick heat transfer, large cooling area and the like.
Description
(1) technical field
The utility model relates to a kind of instrument box electric heater.Be mainly used in the antifreeze and insulation of the instrument box of industries such as oil, chemical industry, medicine, can work under explosive gas atmosphere, it also uses applicable to the well mouth of oil well incubator.Belong to the electrothermal device technical field.
(2) background technology
Instrument box electric heater heat radiation operation principle:
The instrument box electric heater is by its core parts electrothermal tube heating.Be that power supply (adopting the 220V alternating current usually) produces Joule heat to electrothermal tube energising back, heat sees through and follow-up continuing of electric heating tube wall is delivered to instrument box inside by the heat dissipation metal fin by heat conduction and radiation mode, reaches the antifreeze and insulation purpose to gauge pipe in the case.
Former instrument box heater radiator structure is as depicted in figs. 1 and 2: the electrothermal tube radiating mode of the instrument box electric heater that heat conduction is fast is at electrothermal tube added metal radiating fin, because of different electrothermal tube power and dimensional requirement differ, radiating fin size disunity, cooling surface area is less, and heat-transfer effect is not obvious.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides the heat conduction that a kind of heat conduction is fast, area of dissipation is big fast instrument box electric heater.
The purpose of this utility model is achieved in that the instrument box electric heater that a kind of heat conduction is fast, comprise aluminium section bar radiating block and cast aluminium electric heater, described aluminium section bar radiating block center is provided with a through hole, aluminium section bar radiating block outer rim is provided with two horizontal bars, described two horizontal bars are symmetricly set in the left and right sides of aluminium section bar radiating block outer rim, be provided with some first gear pieces on described two horizontal bars, described first gear piece is divided into two rows, two ranked first the both sides, front and back that gear piece is symmetrically arranged in described horizontal bar, vertical mutually with described horizontal bar; Also be provided with two second gear pieces in aluminium section bar radiating block outer rim, two second gear pieces one in front and one in back are symmetrically arranged in the middle of the described aluminium section bar radiating block outer rim, and with described first gear piece layout that is parallel to each other, the aluminium section bar radiating block is sleeved on the cast aluminium electric heater.
Operation principle:
The instrument box electric heater that heat conduction is fast generates heat by its core parts electrothermal tube.Be that power supply (adopting the 220V alternating current usually) produces Joule heat to electrothermal tube energising back, heat sees through and follow-up continuing of electric heating tube wall is delivered to instrument box inside by the aluminium section bar radiating block by heat conduction and radiation mode, reaches the antifreeze and insulation purpose to gauge pipe in the case.
The beneficial effects of the utility model are:
By the aluminium section bar radiating block is sleeved on the cast aluminium electric heater, can promptly conduct heat to the radiating block outer surface, cast aluminium electric heater overall dimensions can be unified to be provided with.It has that volume is little, aesthetic in appearance, heat radiation evenly, characteristics such as heat conduction is fast, area of dissipation is big, thereby the useful life that guarantees electrothermal tube is long more a lot of than general instrument box heater, work that can be reliably and with long-term.
