| The performance of the thermal siphon pump in compact solar pumpless LiBr absorption refrigerating will have a decisive impact,which is one of the key equipment in the refrigerator.Its solution raising pipe is of its core components.The performance to raise the solution determines the siphon pump's performance,which determines the performance of the refrigerator.At present,compact solar pumpless LiBr absorption refrigerator can not promote the use of the biggest obstacles exist in that the siphon's efficiency is not high,especially circle channels throughout the heating riser even more so,with the result that the efficiency of solar collectors is very low.As a result,siphon pump designed to enhance its efficiency is top priority.Circle siphon pump because of its few of vaporization core,even in the full heat of the bubbles generated by its less,with the result that its capacity is difficult to meet the design requirements,so there is more difficult to promote.In addition,the triangle thermal siphon pump due to an increase of vaporization core has greatly enhanced the efficiency,but the start of its heat source temperature can only be reduced to 68, which still fail to improve efficiency,reduce heat to start temperature requirements. Through the analysis we found that increasing the number of vaporization cores,the number of bubbles can be generated in order to be able to raise large amount of solution.Therefore,this paper comes up with triangle thermal siphon pumps,from both experimental and simulation to study it.First of all,analysis the triangle thermal siphon pump's running and working principle in theory;second,arrived at the result that the relationship between triangle thermal siphon pump and operating temperature, a high level,as well as the degree of vacuum;third,after the final simulate the factors which impact on the triangle thermal siphon pump。... |
