摘要：

A detailed cycle analysis of a magnetic refrigerator equipped with new heat switches was performed, including heat losses due to heat switches. The results show that heat loss related to incompleteness of heat switches mainly results in a reduction of cooling power. The experimental heat loss is approximately eight times larger than the calculated value in cases where heat exchange by conduction between a magnetic element and liquid helium is considered. It is believed that this large heat loss may be caused by unexpected convection of liquid helium.
