Abstract
The utility model relates to a meter box electric heater with large cooling area, which is mainly applied to the anti-frost and heat insulation of meter boxes in petroleum, chemical engineering, medical and other industries. 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); the four corners of the outer edge of the aluminum profile cooling block (1) are designed into an inclined rib (12) shape; each inclined rib (12) is provided with a plurality of first tooth slices (13); the first tooth slices (13) are classified into two categories, wherein one category is horizontally deployed on the inclined ribs (12) and the other category is vertically deployed on the inclined ribs (12); the outer edge of the aluminum profile cooling block (1) between the adjacent two inclined ribs (12) is also provided with second tooth slices (14); the second tooth slices (14) are also classified into two categories, wherein one category is horizontally deployed on the outer edge of the aluminum profile cooling block (1) and the other category is vertically deployed on the aluminum profile cooling block (1); and the aluminum profile cooling block (1) is sleeved on the cast aluminum electric heater (2). The meter box electric heater with large cooling area 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 area of dissipation is big 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 area of dissipation that a kind of heat conduction is fast, area of dissipation is big big instrument box electric heater.
The purpose of this utility model is achieved in that the instrument box electric heater that a kind of area of dissipation is big, 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 all is arranged to the diagonal bar shape for four jiaos, be provided with some first gear pieces on described each diagonal bar, described first gear piece is divided into two classes, one class is horizontal arrangement on described diagonal bar, another kind ofly on described diagonal bar, be arranged vertically, and the aluminium section bar radiating block outer rim between adjacent two diagonal bars also is provided with second gear piece, second gear piece also is divided into two classes, one class is in described aluminium section bar radiating block outer rim horizontal arrangement, another kind ofly be arranged vertically in described aluminium section bar radiating block outer rim, the aluminium section bar radiating block is sleeved on the cast aluminium electric heater.
Operation principle:
The instrument box electric heater that area of dissipation is big 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.
