Abstract
The utility model discloses a submersible anticorrosion PTC(positive temperature coefficient) water heater, which comprises an aluminum casing, a PTC heating element and a power supply lead. The PTC heating element is mounted in the aluminum casing, the power supply lead is connected with the PTC heating element, the aluminum casing covers an anticorrosion metal tube, and the anticorrosion metal tube is attached with the aluminum casing closely so as to realize better heat-transfer contact. The anticorrosion metal tube cannot be corroded even when being immersed into water heated for a long time, or being immersed into high-corrosion water or water containing acid, alkali or oxidizer. When the surface of the aluminum casing is attached with water scale, the water scale of the aluminum casing can be removed by means of acid pickling or alkali washing. A covering structure is favorable for transferring heat generated from the PTC heating element in the aluminum casing to the anticorrosion metal tube.
Description
Technical field
The utility model relates to a kind of corrosion-resistant PTC water heater, more particularly, relates to a kind of water heating of doing shell with corrosion resistant metal and uses ptc heater.
Background technology
PTC water heater is in the past generally done shell with aluminium.But because the aluminium corrosion resistance is poor, after the use long period, the aluminium shell can be corroded, even can not use in the immersion water.And because long-term the use, incrustation scale can appear in the aluminum heater case surface, is difficult to remove.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective of the prior art, provide a kind of can acid and alkali resistance, oxide etch, but also can use the corrosion-resistant PTC water heater of water flowing type of removing the incrustation scale of shell through pickling, alkali cleaning.
For realizing above-mentioned purpose; The technical scheme that the utility model provides is following: provide a kind of water flowing type corrosion-resistant PTC water heater, comprise aluminum enclosure, be installed in the PTC heating element heater in the aluminum enclosure; With the power supply lead wire that the PTC heating element heater is connected, coated in the said aluminum enclosure have a corrosion resistant metal pipe.
The beneficial effect of the described corrosion-resistant PTC water heater of the utility model is: the corrosion resistant metal pipe immerses the water midium or long term and adds hot water, even the bigger water of corrosivity, contains acid, alkali or contains the water of oxidant, can not corroded; After case surface is adhered to incrustation scale, can also remove the incrustation scale of shell through pickling, alkali cleaning, the heat that coated formula structure helps the PTC heating element heater generation in the aluminum enclosure is transmitted to the corrosion resistant metal shell.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the corrosion-resistant PTC water heater of the described water flowing type of the utility model is described further.
Fig. 1 is the cutaway view of the corrosion-resistant PTC water heater of the described water flowing type of the utility model.
The specific embodiment
Below be the most preferred embodiment of the corrosion-resistant PTC water heater of the described water flowing type of the utility model, therefore do not limit the protection domain of the utility model.
With reference to Fig. 1, provide a kind of water flowing type corrosion-resistant PTC water heater, comprise aluminum enclosure 1, be installed in the PTC heating element heater 2 in the aluminum enclosure 1, the power supply lead wire 3 that is connected with PTC heating element heater 2, coated in the said aluminum enclosure 1 have a corrosion resistant metal pipe 4.
Said corrosion resistant metal pipe 4 fits together with aluminum enclosure 1 closely, forms the good heat transfer contact.
PTC heating element heater 2, corrosion resistant metal pipe 4 are installed in the aluminum enclosure 1, and corrosion resistant metal pipe 4 is to be formed by materials processings such as stainless steel, corronil, nichrome or titaniums; Closely contact between said corrosion resistant metal pipe 4 and the aluminum enclosure 1, in order to heat transfer; This PTC heating element heater 2 is electrically connected with external power supply through power supply lead wire 3.
The heat that PTC heating element heater 2 in the aluminum enclosure 1 produces is transmitted to corrosion resistant metal pipe 4, passes to the water of periphery again, makes water be able to heating.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
Claims (2)
1. corrosion-resistant PTC water heater of water flowing type; It is characterized in that, comprise aluminum enclosure (1), be installed in the PTC heating element heater (2) in the aluminum enclosure (1); The power supply lead wire (3) that is connected with PTC heating element heater (2), coated in the said aluminum enclosure (1) have a corrosion resistant metal pipe (4).
