Abstract

The utility model discloses an electrothermal heater, which is composed of heat diffusion housing and electrothermal member. The heat diffusion housing includes electric heating tube. electrothermal member and solid heat storage materials are defined inside the electric heating tube. The electrothermal member is PTC electric heating strap. The solid heat storage material is filled aroud the PTC electric heating strap. Compared with the prior electrothermal heater ,the utility model electrothermal heater do not need heat transfer heat-guiding mudium of water or vapor, therefore saving tube for heat transfer heat guiding of water or vapor. The housing do not need an excellent enclosure, therefore the structure is simple, reducing the cost, prolong the life-span, using less electricity, reducing the volume and the weight and can be made into a plurality of shapes. Heating temperature can be controlled to prevent the failure of temperature control device. The electrothermal heater is convenient to install, no need for maintenance, double use of alternative current and direct current, wide working voltage and so forth.

Description

A kind of electric heating device

Technical field

The utility model relates to electric heating device.

Background technology

Water heating radiator is the heating system that winter, people used always, but hot-water heating heating installation need heat water with boiler usually, and the pipeline of the circulation of supplying water need to be installed, and invest very greatly, generally only is fit to the concentrated residential quarter use of north inhabitation.For making single resident family or not possessing the resident family heating of central heating condition, the Chinese patent notification number is that the utility model patent of CN2655076 discloses a kind of electric heating device, it comprises heating cabinet, in heating cabinet, be provided with water inlet and delivery port, described water inlet, delivery port and heating installation circulating water line join, be provided with electric heating tube in the heating cabinet, the heating cabinet tank wall of individual layer atactic copolymerized polypropene (PPR) is as the tank wall and the heat-insulation layer of described heating cabinet, between the water inlet of heating cabinet and delivery port, circulating pump is housed, the expansion water supply tank is arranged above heating cabinet, have the fresh water water supplement port on the described expansion water supply tank, the pipeline before the bottom of described expansion water supply tank and the inlet of circulating pump linked to each other by communicating pipe.The electric heating device of this spline structure has circulating water line, and circulating water line requires sealing, and therefore, it is higher to exist manufacturing cost, the deficiency that service life is short.And this electric heating device also needs complicated attemperating unit and controls heating-up temperature, in case attemperating unit is malfunctioning or short circuit, causes the generation of serious accident easily.

The utility model content

Technical problem to be solved in the utility model is: the electric heating device that a kind of with low cost, safe and reliable, long service life is provided.

The scheme of the utility model technical solution problem is: a kind of electric heating device, form by identical with the hot water radiation structure or similar housing and heating, and in described housing, be provided with heating, this heating is the PTC heat tape.

Described electric heating body is a PTC heat tape that is connected in series with in the electric heating tube.

Filling solid-state heat-storing material with around the heating in housing, so not only making electric heater have thermal capacitance preferably, heating is securely fixed between the housing.

Described solid-state heat-storing material is the silicate cement gel material, and normally used is cement mortar.

The surface of the housing of described electric heating device is provided with the far infrared coating.

The utility model electric heating device adopts such structure, compare with the electric heating device of prior art, do not need to carry by the heat-conducting medium heat of water or vapour or oil again, therefore save the heat of water or vapour or oil and carried thermal conductive pipe, housing does not need excellent sealing yet, and is therefore simple in structure, reduced cost, prolong service life, be applicable to the use of single resident family.The utility model is owing to adopt ptc material to do heater element, and heating-up temperature can be controlled well, attemperating unit malfunctioning problem easily can not occur, and simple installation, has non-maintainingly, and AC and DC is dual-purpose, advantages such as wide cut operating voltage.Electric heating tube can be made multiple shape easily, so that obtain best radiating effect.

Description of drawings

Fig. 1 is the structural representation of the utility model electric heating device;

Fig. 2 analyses and observe enlarged diagram for A-A shown in Figure 1;

In Fig. 1, Fig. 2,1, loam cake; 2, lower cover; 3, thermal source radiation pipeline; 4, PTC heat tape; 5, cement mortar; 6, electric heating tube; 7, fin; 8, power line; 9, leakage protecting plug.

The specific embodiment

As Fig. 1; shown in Figure 2; a kind of electric heating device; mainly comprise radiator casing; PTC heat tape 4; cement mortar 5; the structure of radiator casing is identical with hot water radiation structure commonly used; radiator casing is by loam cake 1; lower cover 2 and loam cake 1 are formed with the parallel thermal source radiation pipeline 3 between the lower cover 2; each thermal source radiation pipeline 3 by be provided with on electric heating tube 6 and the electrical heating tube wall fin 7 form; loam cake 1; lower cover 2 and the thermal source radiation pipeline between them 3 connect; the cross section is that flat PTC heat tape 4 passes through loam cake 1; lower cover 2 is connected in series with in each electric heating tube, and PTC heat tape 4 is connected with the power line 8 of band leakage protecting plug 9.Be filled with cement mortar 5 around the PTC heat tape 4 that is provided with in the electric heating tube 6.For specious and have health physical therapy effect, the surface of thermal source radiation pipeline 3 is coated with sheath, and this sheath is made up of the far infrared coating and the outer field decoration antioxidation coating of internal layer.Anti-oxidation multi-functional sheath also can be decorated for one deck far infrared in the surface of thermal source radiation pipeline 3, and so only needing once, spraying gets final product.

The utility model electric heating device adopts such structure, compare with the electric heating device of prior art, do not need to carry by the heat-conducting medium heat of water or vapour or oil again, therefore save the heat of water or vapour or oil and carried thermal conductive pipe, housing does not need excellent sealing yet, therefore simple in structure, reduced cost, prolonged service life, can make multiple shape.Employing has the PTC heat tape of switching characteristic and memory characteristic, can be from adjusting power, and compensation automatically, the worry of energy-conservation, constant temperature, no high temperature hotspot; The low temperature fast starting, temperature is even, and the limit temperature need not to set up temperature controller automatically, but also accumulation of heat heat release of instant-heating; Simple installation, non-maintaining, AC and DC is dual-purpose, the wide cut operating voltage.Radiator casing the far infrared low-temp radiating that forms of far infrared coating, can play the effect of health-care physiotherapeutic to human body.The decoration antioxidation coating of radiator casing surface makes electric heating device specious.

The utility model is not limited to said structure, and the PTC heat tape in the electric heating tube of radiator casing can directly utilize and connect the clamping of fin support plate.Also the cavity shape of the electric heating tube of radiator casing can be made the shape that adapts with the PTC heat tape.Can filling colloid heat accumulating around the PTC heat tape that is provided with in the electric heating tube, the PTC heat tape more than two can be set in the electric heating tube.
