Abstract
The invention provides a photovoltaic electric water heater, which is a solar panel arranged on an outdoor wall, a balcony and a roof. The provided low-voltage direct-current power is directly used for an indoor low-voltage electric water heater, wherein the low-voltage electric water heater comprises a thermal-insulation heat-storage oil tank, an interior PTC (Positive Temperature Coefficient) electric-heating ceramic element and a heat exchanger. The photovoltaic electric water heater has a simple structure and good freezing resistance, and is safe.
Description
Technical field
The present invention is a kind of water heater, refers in particular to a kind of photovoltaic electric water heater that contains solar panel.
Background technology
Existing flat solar water heater can be positioned on balcony and the roof, but it is heavy, and water pipe easily freezes therefore frost resistance is relatively poor when winter.
Summary of the invention
The purpose of this invention is to provide the good photovoltaic electric water heater that contains solar panel of a kind of frost resistance.
Its technical scheme is as follows: solar panel provides low-voltage DC directly for indoor low-voltage electric water heater.
Its advantage is, direct-furnish low tension safety is simple again, solved the problem of frost resistance, after overcast and rainy and winter also can be with the civil power step-down rectifier for low-pressure water heater.
The specific embodiment
Photovoltaic electric water heater of the present invention, adopt the thin-film solar cell panel of 12V-200W, it is installed in the wall of building south orientation, on windowsill and the balcony, not only sunshade but also generate electricity, and low-voltage electric water heater is made of the thermal isolation and heat storage fuel tank of in-built PTC electric ceramic element and heat exchanger, approximately in 100 liters the thermal isolation and heat storage fuel tank cottonseed oil is housed, also available silicone oil, the benzenoid form conduction oil, certainly, the corrugated stainless steel tubing that also has an end closure in the thermal isolation and heat storage fuel tank, the swollen bad oil case with grease proofing expanded by heating, the PTC electric ceramic element of 12V-160W is contained in thermal isolation and heat storage fuel tank low inside and puts, and the heat exchanger that powerful heat-transfer pipe is coiled into is installed in the position, middle and upper part, itself and running water UNICOM, and the tap of fetching boiling water can be emitted hot water immediately.
Photovoltaic electric water heater of the present invention, also supporting have a family expenses step-down rectifier device, the 220V civil power can be transformed into the 12V direct current for low-voltage electric water heater overcast and rainy.
Claims (2)
1. photovoltaic electric water heater that is comprised of solar panel, heating, heat exchanger, thermal isolation and heat storage fuel tank is characterized in that: solar panel provides low-voltage DC directly for indoor low-voltage electric water heater.
2. photovoltaic electric water heater as claimed in claim 1, it is characterized in that: low-voltage electric water heater is the thermal isolation and heat storage fuel tank that PTC electric ceramic element and heat exchanger are housed.
