Description

Heat pipe cabinet

Technical Field

The utility model relates to a heat pipe rack belongs to rack heat dissipation technical field.

Background

The heat pipe is a heat transfer element which realizes heat transfer by means of phase change of liquid in the heat pipe. The heat conduction device fully utilizes the heat conduction principle and the quick heat transfer property of the phase change medium, the heat of a heating object is quickly transferred to the outside of a heat source through the heat pipe, the heat conduction capability of the heat pipe exceeds the heat conduction capability of any known metal, and the heat pipe does not need to do work from the outside, namely, the energy consumption is zero.

Specifically, the heat pipe utilizes the phase change process of medium evaporating at the hot end and then condensing at the cold end (i.e. utilizing the latent heat of evaporation and condensation of liquid) to make heat quickly conducted. A typical heat pipe consists of a pipe casing, a wick and end caps. The interior of the heat pipe is pumped into a negative pressure state and filled with proper liquid, and the liquid has a low boiling point and is easy to volatilize. The tube wall has a wick that is constructed of a capillary porous material. When one end of the heat pipe is heated, the liquid in the capillary tube is rapidly changed into gas, the gas flows to the other end under the power of heat diffusion, and is condensed at the cold end to release heat, so that the gas is changed into liquid. The liquid flows back to the evaporation end along the porous material by capillary action, and the circulation is not continued until the temperatures at the two ends of the heat pipe are equal (at the moment, the heat diffusion of the steam stops). This cycle is rapid and heat can be conducted away from the heat source.

A cabinet is a freestanding or self-supporting enclosure for containing electrical or electronic equipment. The cabinet is generally a cuboid, is placed on the ground, consists of a frame and a cover plate (door), and is provided with the door, a detachable or non-detachable side plate and a back plate. In an IDC (internet data center) room, a cabinet is generally referred to as a server cabinet and is used for assembling and installing panels, plug-ins, plug-in boxes, electronic elements, devices, mechanical parts and components to form a whole, so that a proper working environment and safety protection are provided for internal electronic equipment.

Therefore, the cabinet should have good rigidity and strength, good electromagnetic isolation, grounding, corrosion resistance, noise isolation, and other properties, and also need good dustproof, waterproof, and heat dissipation properties.

At present common rack radiating mode, including natural convection cooling, fan cooling, the air conditioner air cooling, refrigeration plant cooling etc. all there are some not enoughly:

the natural convection cooling and the fan cooling are adopted, and a perforated plate type cabinet plate is needed, so that the cabinet cannot be sealed, dust is easily introduced, and the working reliability of the electronic equipment is influenced.

The air conditioner is adopted for cooling, so that a larger building space is needed, and the energy consumption is higher.

The refrigeration equipment is adopted for cooling, so that condensed water is easily generated, and the normal work of the electronic equipment is endangered.

The utility model overcomes prior art exists not enough, provides a heat pipe rack, through arranging the heat pipe at the rack body and inside electronic equipment room, directly derive the rack with generating heat of electronic equipment, can realize that the rack is totally closed, zero energy consumption dispels the heat to effectively reduce computer lab PUE.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a heat pipe cabinet, includes rack and heat pipe, the heat pipe is fixed to be set up in the rack, the rack is full seal structure, many heat pipes have been laid in the rack, the evaporation zone laminating of heat pipe sets up on the electronic equipment of installation in the rack, the condensation segment laminating of heat pipe sets up in the roof inboard of rack, the roof outside of rack is provided with radiating fin.

The top plate and the radiating fins of the cabinet are integrally formed, or the radiating fins are used as the top plate of the cabinet, and the condensation section of the heat pipe is directly attached to the lower sides of the radiating fins.

When the radiating fins are used as top plates of the cabinet, the condensing sections of the heat pipes are inserted into or penetrate through the radiating fins.

One or more heat pipes are arranged on the electronic equipment.

The interlude of heat pipe sets up along the lateral wall of rack.

The evaporation section and the condensation section of the heat pipe are connected with the top plates of the electronic equipment and the cabinet through heat conducting glue.
