Embodiment Construction

[0026] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings.

[0027] Such as Figure 1 to Figure 7 A melon petal heat sink shown includes a door heat sink 2 , an upper table heat sink 3 , a middle table heat sink 4 , a lower ball table heat sink 5 and a bottom heat sink 6 located inside a spherical vacuum tank 1 . The upper ball table heat sink 3 is located in the middle of the spherical vacuum tank 1 and is arranged symmetrically about the center of the vacuum tank. The three spherical table-shaped heat sinks are installed independently of each other, and there are independent liquid nitrogen inlet and outlet pipes, which can better control the temperature uniformity of the heat sink. The gate heat sink 2 and the bottom heat sink 6 are arranged oppositely, and are respectively arranged at the top and bottom of the spherical vacuum tank 1 . The door heat sink 2 is installed on the inner surface of the vacuum ...

Abstract

The invention provides a melon petal heat sink. The melon petal heat sink comprises a gate heat sink body, an upper bulb heat sink body, a middle bulb heat sink body, a lower bulb heat sink body and abottom heat sink body which are positioned at the inner side of a spherical vacuum tank. The gate heat sink body is arranged opposite to the lower bulb heat sink body. The middle bulb heat sink body,the middle bulb heat sink body and the lower bulb heat sink body comprise a plurality of melon petal heat sink bodies surrounding the spherical vacuum tank. Each melon petal heat sink body comprisesfins, liquid nitrogen branch pipes, a liquid inlet collecting main pipe and a liquid outlet collecting main pipe. The heat sink structure is convenient to manufacture and transport, and the temperature uniformity is good.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a melon petal heat sink. Background technique [0002] The large-scale spherical space environment simulator is used for thermal vacuum and thermal balance tests of aerospace products, and the large-scale spherical heat sink is the most important part of the simulator. A large spherical heat sink is installed in a large spherical vacuum tank, and the heat sink covers the entire inner surface of the vacuum tank. The heat sink is welded by copper fins and stainless steel tubes. Liquid nitrogen is passed through the stainless steel tubes, and the heat transfer is carried out in the vacuum tank. A temperature environment of about 100K is formed in the spherical vacuum tank with a temperature uniformity of 5K to meet the test requirements. [0003] Since the large spherical heat sink has a diameter of more than 10 meters, the manufacture, transportation and installation...
