Problems solved by technology

[0002] The disadvantage of vacuum tube solar collectors is that the heat exchange efficiency between the heat-absorbing coating in the solar vacuum tube and water is greatly reduced after a period of use
The reason is that the impurities in tap water become scale and accumulate on the inner wall of the solar vacuum tube after being heated, so when the scale on the inner wall of the solar vacuum tube accumulates

Abstract

The invention discloses a solar energy water heater with a self-cleaning vacuum tube water scale function. The solar energy water heater comprises a water box, a base and vacuum tubes arranged betweenthe water box and the base, wherein the base is internally provided with a round cavity arranged in the horizontal direction, the lower end of each vacuum tube is provided with a rolling ball screw rod in a running through manner, joints between the rolling ball screw rods and the corresponding vacuum tubes are in seal rotating connection, the lower end of each rolling ball screw rod is fixedly connected with a gear, the inner wall of the round cavity is slidably connected with a toothed bar engaged with the gears, the round cavity is internally provided with a pushing mechanism used for pushing the toothed bar to move, the pushing mechanism comprises a first stretching and contracting air bag arranged inside the round cavity, and the first stretching and contracting air bag is internallyprovided with a second stretching and contracting air bag. The solar energy water heater with the self-cleaning vacuum tube water scale function is novel in conception, water scale on the inner wallsof the solar energy vacuum tubes can be removed, and the heating efficiency and service life of the solar energy vacuum tubes are guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar water heater with the function of self-clearing scale in vacuum tubes. Background technique [0002] The disadvantage of the vacuum tube solar collector is that the heat exchange efficiency between the heat-absorbing coating in the solar vacuum tube and water is greatly reduced after a period of use. The reason is that the impurities in tap water become scale and accumulate on the inner wall of the solar vacuum tube after being heated, so when the scale on the inner wall of the solar vacuum tube accumulates to a certain extent, the heat exchange efficiency between the heat-absorbing coating and water will be reduced, and the scale is too thick Sometimes the heat-absorbing coating on the solar vacuum tube cannot be dissipated in time due to heat, and under such a high temperature state for a long time, the heat-absorbing coating will fall off, thereby affecting...
