Abstract
The utility model discloses a PTC heating unit, comprising a thermal insulation part and a heating part. The heating part is a cast member formed by casting a PTC heating block and a profiled heating tube for heating with thermal conductive material. The thermal insulation part coats the periphery of the cast. Double surfaces of the heating unit are contacted with the heating tube for heating, thereby provided a large heat conduction area and remarkable effect.
Description
Technical field:
The utility model relates to a kind of instant electric water heater's electro-heat equipment, particularly a kind of PTC heater that is used for the instant electric water heater.
Background technology:
At present, water heater mainly contains following two big classes: a class is that combustion gas is Instant heating type, and this class water heater causes its thermal conversion rate low because of its mode of heating, can produce pernicious gas in the use, contaminated environment, and inflammable, explosive, easily cause human casualty accident.This for this reason water heater is eliminated.And during the current forced-ventilated gas water heater exhaust of generally using, easily produce negative pressure, and noise is big.So only should use, but central hot water apparatus mode causes water resource waste serious as central heater;
Another kind of is the electric heating storage-type.Its defective is that volume is big, and it is many to take up room, and preheating time is long, can not use continuously, and heat leaks very big.Existing electric thermostatic type water heater is owing to using traditional exothermic material to cause thermal conversion rate low, and service life is not long, and problem such as in use, corrosion can appear in heating, easily leaks electricity, and safety coefficient is not high.Since the semiconductor exothermic material comes out, multiple semiconductor liquid heater has also appearred, and its great majority are small-sized water tank type.Can't produce in batches owing to its design problem.Therefore in fact the semiconductor liquid heater is not fully used.
Heated electric water heater heated multipurpose heater single face in the market contacts with copper pipe and carries out the heat conduction, the heat conducting heating of this kind single face is efficient below 90%, another side then wastes heat simultaneously, a heat of waste all is dispersed into the heater surrounding space, and sharp to the harmful nothing of instant electric water heater's internal structure.
The utility model content:
The utility model in existing deficiency aspect the heating, and provides heater on a kind of instant electric water heater of being used at above-mentioned existing instant electric water heater, and two-sided the contact with copper pipe of this heater generated heat, and heat transfer area is big, and effect is remarkable.
In order to achieve the above object, the technical solution adopted in the utility model:
PTC heater, this heater comprise insulating sections and heating part two parts, the foundry goods that described heating part forms by the Heat Conduction Material founding for the special-shaped heating tube by PTC heating piece and heating usefulness, and described insulating sections is coated on the periphery of this foundry goods.
Described PTC heating piece is formed the both sides up and down that are placed in foundry goods of its even distance by PTC heating material outer wrapping insulating barrier.
Described special-shaped heating tube is a copper pipe, on its space between PTC heating piece of evenly gathering with snakelike shape, to reach the maximum thermal effect that adds.
Described special-shaped heating tube is round outside but spuare inside shape, and its inwall is provided with the inside groove tooth of four symmetries, and pipe interior is divided into four sector spaces and a square space.
Described Heat Conduction Material adopts the splendid aluminium of heat conductivility.
Described insulating sections is made of from outside to inside stainless steel coating layer and asbestos heat-insulation layer.
According to the utility model that technique scheme obtains, the two-sided contact with heating tube of its heater generated heat, and heat transfer area is big, and effect is remarkable.The utility model realization simple in structure, easy can provide the heating of more increasing efficient for the instant electric water heater, and its heating is efficient about 96%～～98%, can also provide more convenience for instant electric water heater's structure space design simultaneously.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the schematic diagram of arranging of heating tube.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
There is the efficient not high problem of heating in the utility model at existing instant electric water heater, has adopted structure as shown in Figure 1 to solve this problem.
As shown in Figure 1, whole calandria is divided into two parts: heating part and insulating sections.Heating part is a square aluminum foundry goods 11, and it has PTC heat block 10 and special-shaped heating tube 6 to form by aluminium water founding together.Efficient in order to reach very high heating, the both sides up and down that are arranged on foundry goods 11 of the even distance of PTC heat block, it is formed by PTC heating material 4 outer wrapping insulating barriers 3; Simultaneously special-shaped heating tube 6 adopts copper pipes, and it evenly gathers on the space between PTC heating piece with snakelike shape (as shown in Figure 2), to reach the maximum thermal effect that adds; Owing to be to adopt aluminium water to cast, between PTC heat block 10 and special-shaped heating tube 6, fill by die casting aluminium 5, can reach the extraordinary thermal effect that adds.
The special-shaped heating tube 6 of the utility model employing simultaneously is round outside but spuare inside shape, its inwall is provided with the inside groove tooth 7 of four symmetries, pipe interior is divided into four sector spaces 8 and a square space 9, help special-shaped heating tube 6 more effective heats like this and pass on the current that pass through in the pipe heater, thus the water that will flow in will managing heating.
The utility model also is provided with very effective insulating sections in the periphery of heating part, this insulating sections is made up of stainless steel coating layer 1 and asbestos heat-insulation layer 2, the outside face that asbestos heat-insulation layer 2 is coated on whole heater plays insulation effect, simultaneously one deck stainless steel coating layer 1 is set at asbestos heat-insulation layer 2, can either reach heat insulation effect like this, improve the intensity of whole calandria, prolonged its service life.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
