Because the hot fluid is heated in a flowing manner, heat still flows away if the heat is not exchanged in time (traditional electric heating and fuel oil heating are that a heat source is always maintained in a water storage rod tank (namely static heating), heat exchange efficiency is high and low, the heat is finally released into water, the heat exchange efficiency is affected only by a long heating time end and cannot cause excessive increase of heat loss), the heat flowing away along with the hot fluid is equivalent to heat loss, and the existing steam generator is heated in a static state, so that water is kept still in the heating process (because the static heating does not need water to move), and the heat exchange speed between the heat exchanger and the water is slow; the position of the heat exchanger is fixed, when the water levels are different, the difference of the utilization rate of heat is large, especially when the distance between the heat exchanger and the liquid level is large, the ratio of the heat dissipated by the heat exchanger along the direction far away from the liquid level to the heat transferred by the heat exchanger towards the liquid level direction and the heat evaporated by initial water is large, the larger the ratio is, the lower the heat utilization rate is, all the heat exchangers are installed to be suitable for being close to the liquid level and far away from the bottom of the container, but the installation mode can cause the water exchange to be quickly evaporated to the liquid level and descend to cause the heat exchangers to be exposed (namely, the evaporation time is short), therefore, the existing heat exchangers are all installed at the bottom of the container to sacrifice the heat utilization rate and achieve the effect of delaying the evaporation time; the existing heat exchangers exchange heat in a submerged mode, and cannot generate water vapor quickly; solar heating does not achieve the purpose of obtaining solar energy by utilizing a heat pipe.
