Abstract
The utility model relates to a solar water heater. The lower part of a circulating water tank is directly communicated with the lower circulating port of a heat collector through a lower circulating pipe; the upper circulating port of the heat collector is communicated with the upper part of the circulating water tank through an upper circulating pipe connected in series with a check valve; the check valve is connected in parallel with a compulsory circulating water pump; the positive direction of the check valve is the direction from the upper circulating port of the heat collector to the upper part of the circulating water tank; the compulsory circulating water pump is electrically connected with an electric controller with a temperature sensor. When the sunshine is strong and the natural circulation cannot work effectively, the compulsory circulation starts automatically to improve the operation efficiency; since the compulsory circulation is arranged on the upper circulating pipe as a bypass, under the condition of the compulsory circulation, the layered state of the high and low temperature water in the heat collector cannot be damaged, the cold and hot water cannot be mixed, and the upward floating hot water in the heat collector can be sucked out preferentially in the layers; therefore, the utility model greatly improves the useful thermal efficiency under the condition of the compulsory circulation.
Description
Affiliated technical field
The utility model is a kind of solar water heater.
Background technology
The solar water heater of existing employing pumping forced circulation, water pump is located at down on the circulation line, and the pressure of water pump can destroy the layering of high and low warm water in the heat collector, causes cold and hot water to mix, and has reduced the useful thermal efficiency.
The purpose of this utility model provides the composite circular solar water heater that a kind of pumping forced circulation combines with Natural Circulation, can make full use of the heat of hot water in the heat collector, can not mix water, thermal efficiency height.
The utility model content
Structure of the present utility model is: solar water heater cyclic water tank bottom directly is communicated with the following circulation port of heat collector by following circulation pipe, the upper cycling mouth of heat collector is communicated with cyclic water tank top by the upper circular tube that is serially connected with a check valve, said check valve is in parallel with a forced circulation water pump, the forward of check valve is the direction to cyclic water tank top from the upper cycling mouth of heat collector, and the forced circulation water pump is electrically connected with the electric controller that has temperature sensor.The said electric controller that has temperature sensor is the known prior art of those skilled in the art.
Operation principle: when heat collector heat absorption after a little while, water temperature is lower, the forced circulation water pump is not worked, hot water is Natural Circulation, flows out, enters cyclic water tank top through upper circular tube and check valve from the upper cycling mouth of heat collector.When heat collector absorbs heat for a long time, the water temperature height, the electric controller that has temperature sensor makes the forced circulation water pump connect power supply, water pump operation, the pressure of water pump water delivery makes closed check valve, hot water is forced circulation, sends into cyclic water tank top from upper cycling mouth outflow, process upper circular tube and the forced circulation water pump of heat collector.
Beneficial effect: the utility model is the combined-circulation device of being made up of Natural Circulation and forced circulation, and is strong at sunlight, when Natural Circulation can not effectively be worked, and forced circulation starts automatically, improves operational efficiency; Because forced circulation is located on the cocycle pipeline as bypass, under the forced circulation state, the stratification state of high and low warm water can be not destroyed in the heat collector, can not cause cold and hot water to mix, therefore come-up hot water in the heat collector can have been improved the useful thermal efficiency under the forced circulation state greatly by preferential, layering sucking-off.
Description of drawings
Accompanying drawing is the structural representation of embodiment.
The specific embodiment: see embodiment shown in the drawings.The bottom of cyclic water tank 1 directly is communicated with the following circulation port of heat collector group 3 by following circulation pipe 2, the upper cycling mouth of heat collector group 3 is communicated with cyclic water tank 1 top by the upper circular tube 5 that is serially connected with a check valve 4, said check valve 4 is in parallel with a forced circulation water pump 6, the forward of check valve 4 is the direction to cyclic water tank 1 top from the upper cycling mouth of heat collector group 3, and forced circulation water pump 6 is electrically connected with the electric controller 7 that has temperature sensor.
