Embodiment Construction

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] In this article, if there are no special instructions, when it comes to formulas, " / " means division, "×" and "*" mean multiplication.

[0035] A heat pipe includes a lower header 1, an upper header 2 and a tube bundle connecting the lower header and the upper header. The tube bundle includes one or more groups, and each group of tube bundles includes a plurality of arc-shaped heat exchange tubes 4 , The ends of the adjacent heat exchange tubes 4 are connected, so that a plurality of heat exchange tubes 4 form a series structure.

[0036] As attached figure 1 As shown, the heat pipe includes a lower header 1, an upper header 2, a coil 3, and a return pipe 5. The coil 3 is in communication with the lower header 1 and the upper header 2, and the lower header 1 It is the evaporating end, the condensing end includes the upper header 2 and at le...

Abstract

The invention provides a heat pipe. The heat pipe comprises a lower collecting pipe, an upper collecting pipe and pipe bundles through which the lower collecting pipe is communicated with the upper collecting pipe; the number of the pipe bundles is one or more; each pipe bundle comprises a plurality of arc-shaped heat exchanging pipes; the end portions of the adjacent heat exchanging pipes are communicated, and the heat exchanging pipes are made to form a series connection structure; the center lines of the arc-shaped heat exchanging pipes are an arc of concentric circles; and the larger the distance away from the concentric circle center is, the larger the pipe diameters of the heat exchanging pipes are. The invention provides the novel type heat pipe; and due to the optimization arrangement, the heat exchanging efficiency can be further improved, and the heat exchanging uniformity is improved.

Description

Technical field [0001] The invention belongs to the field of heat pipes, and particularly relates to a heat pipe with multiple heat exchange tubes. Background technique [0002] Heat pipe technology is a kind of heat transfer element called "heat pipe" invented by George Grover of the Los Alamos National Laboratory in the United States in 1963, which makes full use of the principle of heat conduction and phase change medium The rapid heat transfer properties of the heat pipe can quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds the thermal conductivity of any known metal. [0003] Heat pipe technology was previously widely used in aerospace, military and other industries. Since being introduced into the radiator manufacturing industry, people have changed the design thinking of traditional radiators and got rid of the single heat dissipation mode that relies solely on high-air-volume motors to obtain better heat dissipation.
