| The research of Linear Fresnel reflective (LFR) collector gains attention from national solar energy research institutions in recent years. Compared to the commercial used trough collectors, linear Fresnel reflector has the advantage of low cost, high space utilization, low wind resistance and simple controlling system.This paper proposes putting the linear Fresnel lens concentrating collector with the vehicle system together considering it’s characteristics of simple structure, low wind resistance. It can provide some heat or electrical energy supply for the logistics army. The article designs a vehicle-mounted folding linear Fresnel lens concentrating collector, making use of the solar concentrator device to provide certain energy supplies for the army. The main contents of this paper includes as the following:1. The article presents the methods of putting linear Fresnel condensing lens field with the logistical troop’s vehicle, making use of the solar concentrator device to provide certain energy supplies for the army. The maximum temperature of the condenser field is related to the area of the collector area, in order to increase the area of the condenser lens field as far as possible.We design the corresponding folding device. The folding device can obtain twice the area of the vehicle’s roof. This paper studies the designed method of the folding mechanism, power sector, the control module and the collector module through theoretical analysis and simulation.2. The paper does some optimized design on the parameters of the vehicle-mounted linear Fresnel condensing lens field. We also do some numerical analysis on the relationships between the width of the mirror element, the height of the collector, the incident angle of the sun’s rays as well as the number of mirror elements with the condensing mirror field’s performance under the circumstances of the shadows and occlusion that the linear Fresnel lens field may appear. We also study the parameters of the mirror field through global optimization, and get the optimization size of the field through software Matlab prepared by an iterative procedure. Finally, we verify the optimized parameters of the mirror field through orthogonal experiment method by Tracepro, which is optical simulation software. The simulation results are consistent with the results of numerical optimization.3. The paper does some research on the thermal collector of the linear Fresnel concentrator field. We also do some analysis on the improvement of the condenser performance after using compound parabolic (CPC) secondary reflector and the surface energy flow density, and on this basis, we establish a heat transfer model based on vacuum collectors using CPC secondary condenser. The paper analysis the amount of heat loss of the collector unit length as well as the average efficiency of the system through computational fluid dynamic (CFD) simulation analysis methods as the operating temperature changes under the confined environment. It also analyzes the relationship between the outlet temperature of the working fluid with the inlet temperature under different flow rate. The study provides a reference for the thermal performance of the linear Fresnel lens concentrating collector field.4. We build the model of the linear Fresnel lens concentrating collector field with the vehicle, and text the folding performance of the mirror field. On this basis, we study of the performance of the condenser and the air drying performance of the collector. The results showed that the vehicle-mounted linear Fresnel condensing lens field has good condenser performance. Making use of the vacuum tube collectors to concentrating the solar energy to heating, system temperature has a faster corresponding to meet the performance requirements of the collector’s temperature. Finally, we text the photo-thermal conversion efficiency of the system, the results show that the photo-thermal conversion efficiency of the linear Fresnel condensing lens field is about 60%.
