Intelligent temperature control materials for batteries and electronic equipment
1. Intelligent temperature control materials for batteries
Use background: In the case of using soft pack batteries and granular batteries, long-term use will cause the ambient temperature to rise, which may cause a series of accidents such as battery explosions.
Proposal: through the combined use of phase change materials and high-strength protective coatings, phase-change materials are used to absorb the heat generated by the battery for a long time, and the ambient temperature is controlled within a safe range. The use of high-strength protective coatings can avoid some Explosive effects due to high temperature.
2. Intelligent temperature control materials for electronic equipment
Use background: The communication IDC computer room generates a large amount of heat, so the communication cabinet refrigeration requirements are very high. In this case, the phase change material can be used as a backup refrigeration device for the IDC computer room air conditioner. When the computer room air conditioner fails or the power fails At the time, the backup equipment can normally cool the IDC computer room to ensure that there will be no other accidents in the communication IDC computer room when the air-conditioning in the computer room is maintained;
In addition, in IDC computer rooms that use phase change materials, in addition to air conditioning and refrigeration, phase change materials can also maintain the indoor ambient temperature, which can also reduce the use time of the air conditioning in the computer room and achieve the effect of energy saving and emission reduction.
Proposal: Put the phase change material in the form of HDPE sheet or aluminum foil bag, etc., and place it in the IDC computer room so that it can maintain the ambient temperature of the computer room, and in the event of an accident, the material can also be sent to the computer room normally. Refrigeration. In addition, this packaging method can also be interspersed in the communication cabinet at intervals.
The working principle of phase change energy saving
Through the zone temperature control, the local temperature of the battery is accurately controlled, the temperature of the general environment is increased, the working time of the air conditioner is reduced, energy saving is 30%-50%, and the service life of the battery is prolonged.
The relationship between battery life and ambient temperature
An overview of the application of phase change energy saving in an integrated thermostat
The communication base station is an important part of the communication infrastructure, and its internal temperature, humidity and cleanliness and other environmental parameters not only directly affect the reliable operation and service life of the communication equipment, but also related to the smooth and safe communication. The area of the communication base station is generally about 10-30 square meters, but the internal heat dissipation of the computer room is the largest (usually 600-2000W), and it runs uninterrupted and high-load throughout the year. Therefore, the air conditioning cooling of communication base stations and the operation management of air purification equipment are always one of the priorities of the maintenance department.
In most parts of Northeast, North China, and Northwest China, the transition time between winter and spring is long and the summer is short, the outdoor temperature is low throughout the year, and the temperature difference between day and night is obvious. Therefore, using the natural cooling in the outdoor air to cool the base station has very broad application prospects and huge energy-saving potential. Phase change materials can passively store and release energy at their typical dissolution temperature, and can be used as energy storage. Using this feature, many forms of energy can be stored and utilized.
