Abstract
The utility model relates to an electric heater with a noise reduction function. The electric heater is an aluminum casting, and the section of the casting is rectangular or circular. A heating body is contained in the casting, the outer layer of the heating body is provided with a heat-resisting insulation layer, and the heating body is electrically connected with a frequency converter outside a furnace. Convex protrusions are arranged on the surface of the casting. One end of the casting is fixed with a flange plate. The electric heater can be heated through an alternating current power supply or a direct current power supply. The electric heating body placed in the aluminum casting can be set according to requirements. The aluminum casting with good thermal conductivity is adopted, the protrusions are arranged on the outer wall of the casting, and therefore heat generated through the electric heating body can be easily dispersed out and enables water to be heated up rapidly, and the effect of noise elimination is benefited.
Description
Technical field
The present invention relates to the heater of water, specifically a kind of take solar energy and electric heating installation as the energy.
Background technology
Central heating has become the major way of city heating, although central heating has preferably environment protecting, because of a large amount of thermal energy consumptions on hot duct, caused the serious waste of the energy, and totally the changes in temperature effect of heating area is very unbalanced.For vast rural area, still continuing traditional heating mode, burn carbon heating, burning boiler hot water heating etc., large, seriously polluted, the uneasy congruent problem of these method ubiquity energy consumptions such as local method.
The applicant's patent ZL200920034170.6, a kind of little, pollution-free, easy and simple to handle, safe and reliable " energy saving and environment friendly heating installation " of a kind of energy consumption that is applicable to rural area and meagrely-populated area disclosed, be comprised of solar energy, electric heat water tank, warmer, water pump, electric heat water tank is communicated with solar energy and warmer respectively; Adopt the electrical bar heating in the electric heat water tank.During use, injected water in the solar energy; Water enters electric heat water tank after by solar energy heating, and water is subject to the continuation heating of electrical bar in electric heat water tank, squeezed into warmer by water pump subsequently, has realized the effect to heating of house.This patent adopts solar energy that water is given heat, has effectively reduced energy consumption; Adopt electrical bar that the water that gives heat is heated again, have that heating is fast, solar energy heating adverse influence in the time of can replenishing rainy weather.This heating installation is easy and simple to handle, pollution-free, safe and reliable, the use such as be particularly useful for the heating of indoor geothermal tube and have a bath, do washing, wash one's hands.The shortcoming that this patent exists is: adopt the mode of electrical bar heating, its heat conduction to water generates is relatively poor, and can produce larger noise, only can adopt AC electric-heating and can not adopt direct current to heat.
Summary of the invention
The object of the invention is to, overcome the deficiency that prior art exists, provide a kind of to water generates heat conductivity preferably, and can abate the noise preferably, both be fit to alternating current and also be fit to the electrically heated electric heater of direct current.
The present invention is achieved in that
The present invention's electric heater is that a cross section is rectangle or the circular long foundry goods of aluminium matter, and foundry goods includes calandria, and the calandria skin has heat-resisting insulating barrier; Cast(ing) surface is uneven---and be beneficial in water and fully dispel the heat; One end of foundry goods is fixed with ring flange---and this ring flange is fixed on the furnace wall, and foundry goods is suspended in the interior water of stove.In power supply circuits, be connected to the frequency conversion instrument, to produce good power savings, as: when starting heater, need electricity consumption 2000W, and reach when giving fixed temperature when water temperature, heat radiation reality only needs power consumption 500W, at this moment, start the frequency conversion instrument---make the power consumption of heating be equal to or greater than true heat gain value, thereby reached the effect of power saving noise reduction.
Said calandria is electrically heated rod or resistance wire etc.
The outer field heat-resistant insulation material of said calandria can be the materials such as porcelain bushing, high temperature resistant silica gel glass.
Said frequency conversion instrument comprises manual frequency conversion instrument or frequency-variable electronic instrument.
The present invention's electric heater is manufactured like this and is formed:
1. design as required diameter and the length of calandria;
2. calandria is sleeved in the sleeve pipe of heat-resistant insulation material;
3. the calandria that will be set with the heat-resistant insulation material sleeve pipe is made given shape, such as bar-shaped or helical form; The two ends connecting power line of calandria;
4. the calandria of given shape is placed on axis zone among the casting die of given shape;
5. cast aluminum liquid in the casting die;
6. slough mould, at an end fixed flange of calandria;
When 7, using, connecting frequency conversion instrument (8) at the power line of mounting flange (3) socket.
The present invention's electric heater can adopt the AC power heating, also is fit to the dc source heating; Because the electric heating body that is placed in the aluminium casting can be decided according to the wattage size; Owing to being the good aluminum material of thermal conductivity, and foundry goods is large, be roughness on the outer wall, therefore the heat of foundry goods more easily is transmitted in the water water is rapidly heated, and more is conducive to reach the effect that abates the noise.
