Description
Способы теплообмена в концевых теплообменниках водородного ИЛИ гелиевого ожижителей известны.Heat transfer methods in the end heat exchangers of hydrogen or helium liquefiers are known.
По предлагаемому способу, в отличие от известных, давление сжатого газа в теплообменнике измен ют по инверсионной кривой. При этом теплопередача интенсифицируетс благодар созданию наибольших разностей температур.According to the proposed method, unlike the known ones, the pressure of the compressed gas in the heat exchanger is varied according to the inversion curve. At the same time, heat transfer is intensified due to the creation of the greatest temperature differences.
Способ основан на том, что хладоороизводительность водородного ИЛИ гелиевого цикла с дросселированием максимальна, если давление сжатого газа равно давлению в точке инверсии при температуре газа после предварительного охлаждени жидким азотом или водородом соответственно . При этом максимальные разности температур в концевом теплообменнике будут в том случае, если в каждом сечении теплообменника давлениепр мого потока равно инверсионному. Таким образом, дросселиру сжатый и охлажденный газ до давлений, соответствующих инверсионным точкам, иначе говор , измен .ч давление сжатого газа по инверсионной кривой, можно получить наибольшие разности температур , а следовательно, и интенсифицировать теплопередачу.The method is based on the fact that the cooling capacity of the hydrogen OR helium cycle with throttling is maximum if the pressure of the compressed gas is equal to the pressure at the inversion point at the gas temperature after preliminary cooling with liquid nitrogen or hydrogen, respectively. In this case, the maximum temperature differences in the end heat exchanger will be if in each section of the heat exchanger the pressure of the direct flow is equal to the inversion flow. Thus, throttling the compressed and cooled gas to pressures corresponding to the inversion points, in other words, by changing the pressure of the compressed gas along the inversion curve, it is possible to obtain the greatest temperature differences, and consequently, to intensify the heat transfer.
Предмет изобретени Subject invention
Способ теплообмена в концевых теплообменниках водородного или гелиевого ожижителей, отл ич а ющи йс тем, что, с целью интенсификации теплопередачи путем создани наибольших разностей температур , давление, сжатого газа в теплообменнике измен ют по инверсионной кривой.The method of heat exchange in the end heat exchangers of hydrogen or helium liquefiers, differing from the fact that, in order to intensify heat transfer by creating the greatest temperature differences, the pressure of the compressed gas in the heat exchanger is changed according to the inversion curve.
