U-shaped heat pipe array device and air conditioning system including it

Abstract

The invention discloses a U-shaped heat pipe array device. The U-shaped heat pipe array device comprises two straight arm parts and a bend part for connecting the two straight arm parts. The two straight arm parts serve a condensation end and an evaporation end and each comprise multiple horizontal pipes; the bend part is a multi-way pipe and used for connecting the horizontal pipes of the condensation end and the horizontal pipes of the evaporation end; a perpendicular primary pipe is further arranged at the end, far away from the bend part, of the condensation end, and is communicated with the multiple horizontal pipes of the condensation end; every two corresponding end openings in the portions, far away from the bend part, of the horizontal pipes of the evaporation end are connected through a connecting pipe. According to the U-shaped heat pipe array device, in air conditioning of the air conditioner industry, the refrigeration industry, the dehumidification industry, the drying industry and the like, as low-temperature cold sources do not need to be prepared for dehumidifying during room temperature control, the use ratio of energy and the comfort degree of the room are increased.

Description

Technical field [0001] The present invention relates to the field of heat exchange, and further relates to a U-shaped heat pipe array device and an air conditioning system containing the device. Background technique [0002] According to the energy-saving design standard for public buildings (GB50189-2005), the indoor temperature in summer is 25℃, and the relative humidity is 40%-60%. According to this requirement, the air dew point temperature is 16.6℃. Therefore, the task of the air conditioner can be seen as extracting heat from a 25°C environment and dissipating it to the outdoor environment, and dehumidifying the indoor air at a dew point temperature of 16.6°C. [0003] The current temperature control and dehumidification of air conditioners use low-temperature chilled water to cool, condense and dehumidify the air, and then send the cooled and dry air into the room to achieve the purpose of removing heat and moisture. [0004] In this process, the fan coil unit should simultan...

AI Technical Summary

Problems solved by technology

[0007] 1. In the process of regulating the indoor environment, in order to meet the requirements of dehumidification, the temperature of the chilled water needs to be lowered to below 7°C, and the temperature control of the room does not require such a low-temperature cold source, resulting in a waste of energy quality

[0008] 2. Although the humidity of the air after condensation and dehumidification meets the requirements, the comfort of the room is reduced due to the low temperature. In order to improve the comfort, sometimes it needs to be reheated, resulting in further waste and loss of energy

[0009] 3. Ordinary heat pipe arrays are made by combining independent heat pipes and thermosiphons. These heat pipes and thermosiphons are all single structures and cannot be made into complex circuits. This not only brings inconvenience to large-scale manufacturing and filling, but also There will be problems with uneven temperature and humidity distribution

In addition, U-shaped arrangement is required for heat recovery of air conditioners, which will adversely affect the heat transfer performance of heat pipes and thermosiphons

The vapor and liquid in the ordinary heat pipe work in the form of countercurrent, and the U-shaped structure makes it difficult to return the liquid

The thermosiphon works in the form of vapor-liquid two-phase circulation convection, and the U-shaped structure will increase the flow resistance and cause unstable work
