"Make a Solar Water Heater" Light PPT Courseware 4

solar water heaters:

It is to use sunlight to heat water to achieve the purpose of benefiting mankind;

It is an energy-saving device designed using a variety of scientific principles.

1. Structure of solar water heater

The solar water heater consists of: collector, thermal insulation water tank, connecting pipes, brackets and control system.

2. Materials for manufacturing solar water heaters

Materials for manufacturing solar water heaters: heat-absorbing materials, insulation materials, water storage tanks, brackets, etc.

Solar water heaters mainly consist of two parts:

1. The collector, the glass tube is double-layer vacuum, and has basically the same structure as the glass inner tank of the thermos bottle, except that a black heat-absorbing layer is coated on the outer surface of the inner glass.

2. Thermal insulation water storage tank, the lower part is connected with the glass heat-absorbing tube.

working principle:

The collector is used to absorb sunlight, convert the light energy into heat energy, and store the hot water through the water storage tank.

work process:

The solar energy is absorbed through the collector tube to heat the cold water, and then the hot water is sent to the insulating box to maintain a certain temperature. When we need hot water, the hot water is released through the control system and a certain amount of cold water is added to the collector for heating.

Design requirements:

1. Can hold 200ml of water;

2. Try to raise the temperature of the water in the water heater within 15 minutes.

think:

In order to make the water heater heat up as quickly as possible, what issues need to be considered? What measures are taken?

What two main parts should it include? (Light absorption, heat generation and heat preservation)

What materials should be used?
