Single-sided corrugated plate type pulsating heat pipe

Abstract

The invention discloses a single-sided corrugated plate type pulsating heat pipe which comprises a bottom plate, a corrugated plate and a first communication cavity and is characterized in that: the bottom plate is a plane metal plate; one end of the bottom plate is provided with the first communication cavity in sealed connection with the bottom plate; the section of the corrugated plate is of a continuous triangular shape, sinusoidal shape or other periodical curve shape; the two ends along the extension direction of the wave of the corrugated plate are in sealed connection with the bottom plate; one end vertical to the extension direction of the wave of the corrugated plate is in sealed connection with the first communication cavity, and the other end is in sealed connection with the bottom plate; two adjacent troughs of the corrugated plate are welded on the bottom plate through spot welding to form multiple pulsating channels vertical to the extension direction of the wave of the corrugated plate; and adjacent channels are communicated through hair cracks. The equivalent coefficient of heat conductivity of the single-sided corrugated plate type pulsating heat pipe is two orders of magnitude higher than that of an aluminum extruded radiator and 2-3 times higher than that of the related flat heat pipe; and the single-sided corrugated plate type pulsating heat pipe can be horizontally mounted and is particularly suitable for recycling the ventilation energy of an air conditioner as well as radiating and cooling electronic devices.

Description

technical field [0001] The invention discloses a single-sided corrugated plate type pulsating heat pipe. It belongs to the technical field of heat exchange equipment. It is suitable for energy recovery of air-conditioning ventilation and heat dissipation and cooling of electronic devices. Background technique [0002] With the development of the economy, air conditioners are used more and more widely, but the energy consumption and air quality are increasingly bothering consumers. According to the "Indoor Air Quality Standards", in order to ensure the air quality, it is necessary to exhaust to the outside and send fresh air to the room. The incoming fresh air must be processed by the air conditioning unit to meet the requirements, while the exhaust air is already processed air, both of which consume energy. If the exhaust and fresh air can perform an energy exchange when entering and leaving the room, the load on the air conditioning unit will be greatly reduced and a lar...

Problems solved by technology

The circular shape has weak capillary action. If you want to increase the capillary action, you need to process microgrooves in the circular channel, which is a complicated process.

The channels are also independent and sealed, and the heat transfer performance of the heat pipe cannot be improved by increasing the frequency of the change of the vapor and liquid plugs

[0013] Judging from the above-mentioned published technical documents, due to the limitations of the working mechanism adopted or the structure of the existing technologies or patents, their heat transfer performance has not yet reached better, and they cannot meet the increasingly stringent requirements. Harsh air conditioning ventilation energy recovery and the need for heat dissipation and cooling of electronic components
