But due to the thermal environment outside, the cargo temperature of in hold-over plate refrigerated vehicles has a steady increase and uneven distribution, which cause the growth and propagation of microorganism and has a bad effect on the quality of refrigerated cargoes.
The effects of cold storage agent′s sort and weight on cold storage capacity in hold-over plate, and effects of cold storage agent′s sort,environmental temperature,solar radiation,leakage from doors etc on charging time are analysed The ways of increasing cold storage capacity in hold-over plate and reducing charging time are put forward This paper will provide theoretical base for design of hold-over plate,transportation and management of hold-over plate refrigerated trucks
This paper concentrates on the study of heat transfer characteristics of rectangular channels Cold-Plate used in electronic devices , The experimental way and three-dimensional numerical simulation method are applied which is just carried out in our country.
Experiments including the measurement between Q and p in the heat exchanger on the cold-plate, dimension of current limiting loop, the LCS flux distribution and the LCS performance simulation under different flight conditions are made.
The structure and accumulating cold mechanism of the cooling plate are described. The properties of the accumulating cold agent are analyzed. Application of the cooling plate to refrigerated van is recommended.
Through tests of measuring the super cooling degree and heat of fusation,it is found that CuS is the best proper nucleating substance for the solution of salt eutectic (KCl) used in the mechanical cooling plate refrigerating wagon,SiO2 is another choice in general.
A study is made of a laminar boundary layer near a cold plate in the regime of weak viscous -inviscid interaction in the limit in which the free-stream Mach number tends to infinity and the temperature factor to zero.
Analysis of heat transfer behaviour of the conduction cold plate system
The heat-transfer behaviour of the conduction cold plate system used for avionics is investigated in this paper.
The steady-state temperature profile for the cold plate is derived and the relationship between the coolant mass flowrate, the heat load and the highest cold plate temperature is established.
A model is proposed to describe the transient thermal rosponse of the cold plate under thermal shock condition.
