Heat leakage influences the non-loss storage of cryogenic liquids directly,so to calculate the quantity of heat leakage accurately is a very important to improve the design of cryogenic vessels.

Several control methods which could avoid heat leakage were made by reasonable design of whole support structure of the cryogenic liquid storage vessel.

The heat leakage of an indirect cool refrigerator s cabinet has been studied.

Through the use of an irreversible Carnot heat engine model of Dulong Petit nonlinear heat transfer rate and heat leakage derived is its basic optimization relation with the issue of the heat engine efficiency during its maximum output power being also discusse

The performance for a class of generalized irreversible universal steady flow heat engine cycle model consisting of two heating branches,two cooling branches and two adiabatic branches with the losses of heat-resistance,heat leakage and internal irreversibility was analyzed and optimized using finite time thermodynamics.

The objective is to minimize their resulting heat leaking into HTS AC magnet.

In order to guarantee the good quality of transfer lines,the numerical thermal simulation of the supports of cryogenic transfer lines were made by FEA package ANSYS by which the heat leak and temperature distribution on the supports of transfer lines were obtained.

The relation of all the heat leak factors is determined The result shows that the heat leak along the radial direction is much more than that along the axial direction.

The heat loss is a significant factor which influences the performance of a puls e tube cryocooler.

Current lead is an important part of a cryogenic device, and it is also one of the main sources of heat loss of the system.
