[ detailed description ] embodiments

The cooling cushion system comprises a micro compressor 1, a condenser 2, an expansion valve 3, an evaporation chamber 4, gel 5, a high-efficiency heat pipe 6, a phase-change material 7 and a power supply 8.

The present embodiment has two operation modes of electricity use and no electricity use during operation, and the two operation modes are described below separately.

The power-on use mode comprises: as shown in fig. 1, the power supply 8 drives the micro-compressor 1 to rotate, so that the low-pressure R134a gas is compressed into the high-pressure R134a gas, the high-pressure R134a gas is condensed into the R134a liquid in the condenser 2, the pressure and temperature of the R134a liquid are reduced after the R134a liquid is expanded by the expansion valve 3, and the expanded low-temperature low-pressure R134a liquid absorbs heat transferred by the high-efficiency heat pipe 6 in the evaporation chamber 4, so that the R134a gas is formed, and the whole cycle is completed.

In the whole electrified use process, the phase-change material 7 transfers energy to the evaporation chamber 4 through the high-efficiency heat pipe 6 so as to store cold.

A no-power use mode: during non-electrical use, the thermodynamic cycle subsystem is not operating and the evaporation chamber 4 is disconnected from the high efficiency heat pipe 6, as shown in fig. 1. When a human body contacts the gel 5 and is heated, the heat is rapidly conducted to the phase-change material 7 through the high-efficiency heat pipe 6, and the phase-change material 7 which stores cold absorbs the heat through phase change to realize cooling.
