Problems solved by technology

During the evaporation process of the heat pipe, it will inevitably carry liquid to the steam end. At the same time, because of the exothermic condensation of the condensation end, there will be liquid in the condensation end, and the liquid will inevitably mix with the steam, so that the fluid in the heat pipe is vapor. Liquid mixture, the existence of vapor-liquid mixture causes the gas to mix together, and the heat exchange capacity between the liquid and the liquid decreases, which greatly affects the heat exchange efficiency

Embodiment 1

[0205] As an improvement, a temperature sensor is arranged in the steam drum 3 for measuring the temperature of the steam in the steam drum 3 . The water inlet pipe 8 and the steam outlet 5 of the steam drum 3 are respectively provided with a water inlet valve and a steam valve, and the temperature sensor, the water inlet valve and the steam valve are connected with the central controller 7 for data. The central controller 7 controls the opening and closing and opening of the water inlet valve and the steam valve according to the temperature measured by the temperature sensor.

[0206] If the temperature of the steam in the steam drum 3 measured by the temperature sensor is lower than the lower limit value, the central controller 7 controls the water inlet valve and the steam valve to automatically close, thereby ensuring that the steam in the steam drum 3 continues to heat up; if the measured steam drum If the temperature of the steam in 3 exceeds the upper limit value, then ...

Embodiment 2

[0212] As an improvement, the central controller 7 ensures that the outlet water temperature in the steam drum reaches a constant value by controlling the opening of the water inlet valve and the steam valve. That is, the temperature of the steam at the steam outlet of the steam drum 3 is adjusted by adjusting the said flow rate entering the steam drum 3 and leaving the steam drum 3 .

[0213] An outlet pipe temperature sensor is set on the steam outlet 5 of the steam drum, and the outlet temperature sensor is connected with the data of the central controller 7, and the central controller 7 controls the opening and closing and opening and closing of the water inlet valve and the steam valve according to the temperature measured by the temperature sensor. degree size.

[0214] If the temperature of the steam in the outlet pipe measured by the temperature sensor is lower than the lower limit value, the central controller 7 controls the opening of the steam valve to increase, red...

Embodiment 3

[0221] As a further improvement of the second embodiment, the opening and closing of the steam valve and the water inlet pipe valve are controlled by measuring the temperature of the water in the steam drum 3 .

[0222] If the temperature of the water in the steam drum 3 measured by the temperature sensor 19 is lower than the lower limit value, the central controller 7 controls the opening of the steam valve to increase, and reduces the opening of the water inlet pipe valve, thereby reducing the water entering the steam drum 3 , so that the steam leaving the steam drum 3 increases, thereby reducing the amount of water in the steam drum 3 . The temperature of the water in the steam drum 3 is increased by reducing the amount of water, thereby increasing the outlet temperature of the steam drum 3 . On the contrary, if the temperature of the water in the steam drum 3 measured by the temperature sensor is higher than the upper limit value, then the central controller 7 controls the...

Abstract

The invention provides a solar steam generator which comprises a reflector and a steam drum. The steam drum is located in a focal position of the reflector, the reflector reflects solar energy to thesteam drum for heating water in the steam drum, a heat pipe starting to stretch upward from the bottom of the steam drum is arranged in the steam drum, a separating device is arranged in the heat pipe, the separating device is of a sheet structure, and the sheet structure is arranged on a cross section of the heat pipe; the separating device is composed of a square through hole and a regular octagonal through hole, the length of side of the square through hole is equal to that of the regular octagonal through hole, four sides of the square through hole are separately four different sides of the regular octagonal through hole and four isolated sides of the regular octagonal through hole are separately four different sides of the square through hole. The solar steam generator further improves the flow stabilizing effect, strengthens heat transfer, and is simple to manufacture.

Description

technical field [0001] The invention relates to a steam generator technology, in particular to a steam generator of a heat pipe with a new structure. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe t...
