Constant-difference type magnetic solar energy heater

Abstract

A constant-difference magnetron solar warmer used in the field of solar energy applications. The working principle is that when the magnetic fields of two permanent magnets are cross-linked in space, regardless of the direction and position of their magnetic poles, a magnetic force will inevitably occur. interaction, and is not affected by the separation and wrapping of any non-magnetic medium, and the force of the two magnets is equal. In the space, let the distance between their magnetic poles be a certain value, and the two magnets form a common magnetic field in this space. Since the distance is a constant value, it is also determined that the gravitational force between them is a certain value. To change Their distance requires a force to be applied to their magnetic pole faces. When the external force is greater than the attractive force between the two magnetic poles, one of the magnets starts to move backward, making their distance longer. The design of the device is novel and scientific, in order to reduce the heat loss caused by the convection between the solar water heater and the atmosphere, and try to achieve the effect of heating up quickly without cooling down.

Description

Technical field: [0001] The invention relates to a constant-difference magnetically controlled solar warmer in the field of solar energy applications. Background technique: [0002] In the past 20 years, the application of solar energy has developed rapidly in all countries in the world, and the development and use of solar energy has become the main way to save energy and reduce emissions. In this field, the development of solar water heaters is particularly rapid, especially in my country, which has become the largest country in the world in terms of production capacity of solar water heaters. There are more than 5,000 brands alone, and more than 30 companies with an annual production capacity of more than 50,000 units , but there are only 21 "environmentally friendly household water heaters" that really meet the national environmental protection requirements. [0003] One of the most critical standards for environmentally friendly household water heaters stipulated by the...

Problems solved by technology

The actual situation is not the case. In the winter in northern my country, even if there is a very good weather with a certain amount of sunshine, only a few brands of water heaters can reach the temperature of 45°C on the same day. The main reason is that Overall thermal efficiency is low

[0004] In order to improve the overall thermal efficiency, two problems must be solved. One is to improve the heat absorption efficiency of the collector to absorb solar energy, and the other is to reduce the heat loss of the solar water heater. At present, people pay more attention to improving the heat absorption efficiency of the heat collector. However, almost no one pays attention to the heat loss of water heaters. The heat loss of solar water heaters is mainly concentrated on the water tank. The water tanks are almost exactly the same; there is a hole of about Φ20mm on the top of the water tank to communicate with the outside atmosphere, and there is also a sensor hole that also communicates with the atmosphere. It is precisely these two holes that dissipate a considerable part of the heat energy with the water vapor, causing the water heater to be damaged. Temperature rises slowly during the day and cools quickly at night
