1) automatic ice bag
Methods 110 patients with fractures or joint and soft tissue injuries were evenly randomized into the observation group and the control group:the former group was intervened with cold compress using automatic ice bag,while the latter using common ice bag.
2) Improved type ice bag
3) natural ice storeage
Numerical simulation of effect of natural ice storeage with conical ice;
4) ice bag
Objective To study the preventive effect of skin damage caused by radiotherapy in head and neck carcinomas with local appication of ice bag and skin repellent.
Objective To know the effectiveness of ice bag cold compress promoting the healing of eye cosmesis wound.
Objective:To observe the curative effect of external applying fresh potato slices and cold compress to treat patients with physic liquor exosmosis of intravenous transfusion,and to compared with ice bag cold compress as well.
5) frost-free refrigerator
PIV measurement and numerical simulation of the inner flow field of freezer chest of frost-free refrigerator;
The freezer chamber of a BCD-190W type frost-free refrigerator was chosen as a research object,and digital particle image velocimetry(DPIV) technology was adopted to investigate the flow fields in the freezer chamber of a transparent refrigerator model.
A transparent model based on a BCD-190W type frost-free refrigerator was constructed with organic glass,and the experiment system for measuring the air flow characters in the cooling chamber of the model was built.
6) Indirect cooling refrigerator
A new electro - magnetic driven damper temperature control system of indirect cooling refrigerator, which consisted of temperature sensor, solenoid, control current and damper, was developed.
