Description

Liquid cooling self-loopa radiator

Technical Field

The utility model relates to a liquid cooling self-loopa radiator, the electronic components cooling heat dissipation that specially adapted calorific capacity is big uses.

Background

Some electronic components, such as integrated blocks, high-power triodes and electron tubes, generate large heat when working, and the heat is not dissipated in time, so that elements are burnt out.

In the industry, aluminum and copper section blocks are generally used for heat dissipation of low-power heating electronic components, and the section blocks used for high-power components cannot quickly and timely dissipate heat.

For high-power electronic components, the other type uses cooling liquid circulation for heat dissipation, and the high-power electronic components comprise a heat absorption exchanger, a connecting pipeline, a circulating pump, a heat dissipation exchanger, a cooling fan and the like, and are complex in structure; the parts have more interfaces and are easy to leak liquid to cause accidents; and requires additional energy to power the cycle.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a simple structure, heat exchange efficiency height, dependable performance do not need a liquid cooling self-loopa radiator of extra energy.

The utility model discloses a task is accomplished like this, its characterized in that: including flat aluminum tube, heat sink bottom plate, refrigerant filling tube, flat aluminum tube has 2 at least, bends along the flat side direction of flat aluminum tube's the U type, and the curved open end of U type inserts the flat downthehole of mainboard, and the clamp is equipped with the fin between every flat aluminum tube and the adjacent flat aluminum tube, and is equipped with the fin in the U type of every flat aluminum tube is bent, the inside cell type that is of heat sink bottom plate constitutes refrigerant circulation inner channel after mainboard and the welding of heat sink bottom plate, it has refrigerant filling tube pilot hole to reserve on the mainboard.

The aluminum flat tube is extruded once, and a plurality of small holes for refrigerant circulation are processed inside the aluminum flat tube to form a circulation channel.

The utility model discloses has following effect: the heat radiator is capable of achieving heat dissipation through self-circulation of the internal refrigerant, simple in structure and high in heat exchange efficiency; the radiator is of an all-aluminum structure, a micro-channel flat tube is used for one-time extrusion, and a plurality of small holes are formed in the radiator and are used as channels for refrigerant circulation; the radiator is suitable for mass production for integral brazing after being assembled.

description of the drawings: 1. the heat sink structure comprises aluminum flat tubes, 2, fins, 3, a main plate, 4, a heat sink bottom plate, 5, a refrigerant filling tube, 6, mounting fixing holes, 7 and a groove type.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The specific embodiment is as shown in the figure, including flat aluminum pipe 1, heat sink bottom plate 4, refrigerant filling tube 5, flat aluminum pipe has 2 at least, bends along the flat side direction of flat aluminum pipe's the U type, and the open end that the U type is bent inserts in the flat hole of mainboard 3, and every flat aluminum pipe presss from both sides between the clamp and is equipped with fin 2 with adjacent flat aluminum pipe, and the U type of every flat aluminum pipe is bent and is equipped with the fin in, and this kind of structure can further increase heat radiating area, heat sink bottom plate inside is cell type 7, constitutes refrigerant circulation inner channel after mainboard and the welding of heat sink bottom plate, it has refrigerant filling tube pilot hole to reserve on the mainboard.

The aluminum flat tube is extruded once, and a plurality of small holes for refrigerant circulation are processed inside the aluminum flat tube and form circulation passing.

The fins are brazed with the main board and the heat sink bottom board to form a whole.

The heat sink bottom plate is welded with the main plate, the heat sink bottom plate is step-shaped when viewed from the side, mounting fixing holes 6 are reserved at two ends of the heat sink bottom plate, one end of the refrigerant filling pipe 5 is inserted into a hole reserved on the main plate, the other end of the refrigerant filling pipe is exposed, the end, exposed out, of the refrigerant filling pipe is vacuumized, then refrigerant with a lower boiling point is injected into the heat sink bottom plate through the refrigerant filling pipe exposed at the end and flows into the heat sink bottom plate through the main plate, and then the end, exposed, of the refrigerant filling pipe is sealed.

When the heat sink bottom plate is in work, the bottom surface of the heat sink bottom plate is tightly attached to the heating electronic element, after the heat sink bottom plate absorbs heat, the refrigerant in the groove is heated, the liquid refrigerant is evaporated and absorbs heat by being in a gaseous state, the gaseous refrigerant rises from a channel in the micro-channel flat tube and dissipates heat through the aluminum flat tube and the fins, the gaseous refrigerant is condensed into a liquid state, and then the liquid refrigerant flows back into the groove of the heat sink bottom plate through the channel in the micro-channel flat. The circulation achieves the effect of rapid heat dissipation.

In the present invention, unless explicitly specified or limited otherwise, the terms "heat sink bottom plate", "aluminum flat tube" and the like are to be understood in a broad sense, for example, the aluminum flat tube may be aluminum flat tubes of different sizes, and holes of different numbers are formed inside the aluminum flat tube. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
