Herein, if without specified otherwise, it is related to formula, "/" indicates that division, "×", " * " indicate multiplication.
A kind of solar steam generator using heat pipe is disclosed picture 1-4, and the steam generator includes reflecting mirror 1
With drum 2, the drum 2 is located at the focal position of reflecting mirror 1, and solar energy reflection is used to heat by the reflecting mirror 1 to drum 2
Water in drum 2, the steam generator further include the heat pipe being arranged in drum 2, as shown in Figure 1, heat pipe setting exists
Inside drum 2, the heat pipe includes header 8 and radiating end 3, and the header 8 is arranged in the bottom of drum 2, the radiating end 3 with
Header 8 is connected to, and the radiating end 3 is upwardly extended since 8 top wall surface of header, and the radiating end 3 is more, the header 8
Bottom be connected on the inner wall of drum 2.
Traditional solar steam generator is all to generate steam by direct irradiation of sunlight drum, utilizes inside steam drum
Heat convection carry out the fluid convection heat exchange of drum upper and lower part, but need lower part hot fluid natural in such cases
It is by convection into top, heat exchange efficiency is low, and the present invention is by being arranged heat pipe in drum bottom, because the gas of the inside is vertical after heat pipe is heated
The evaporation ends for carving the top for the heat pipe that evaporation rises, exchange heat on top, and such heat is just quickly transmitted to drum top,
Heat exchange efficiency can be quickly improved, solar energy heating utilization rate is improved.
The present invention, can by heat first being concentrated in header, heat pipe heat radiation end is then passed in lower end setting header
Quickly to transfer heat away from.
Preferably, the bottom of the header 8 is the inner wall of drum 2.Heat pipe and drum is made to can be used as one in this way
It is whole, using the inner wall of drum as the lower end wall surface of heat pipe, thermal contact resistance is reduced, so that compact overall structure,
Preferably, the drum and heat pipe are to be integrated.
Because solar energy is absorbed, so that stream-liquid two-phase flow occurs in heat pipe, so that the fluid in heat pipe is vapour in heat pipe
Liquid mixture.Therefore this invention takes new structures, to divide liquid and vapor capacity, so that heat exchange is reinforced.
Separator 4 is set in heat pipe, and the structure of the separator 4 is as shown in Figure 5,6.The separator 4 is piece

The effect of vibration noise reduction, improves heat transfer effect.Separator in compared with the existing technology further increases steady flow result, strengthens
Heat transfer, and be simple to manufacture.
2) present invention is by being reasonably laid out, so that square and octagon through-hole are evenly distributed, so that whole
On rank street face on fluid segmentation uniformly, avoid the segmentation of ring structure in the prior art circumferentially and unevenly ask
Topic.
3) present invention is uniformly distributed by the interval of square hole and octagon through-hole, so that macropore and aperture exist
It is evenly distributed on whole cross section, and by the change in location of the macropore of adjacent separator and aperture, so that separating effect
Fruit is more preferable.
4) present invention is laminated structure by setting separator, so that separator structure is simple, cost is reduced.
The present invention is equivalent to by setting square hole and octagon separator and increases interior heat exchange in heat exchanger tube
Area enhances heat exchange, improves heat transfer effect.
