The basic features and design of a new generation coolers made for CSRm,CSRe (Lanzhow, IMP) and for LEIR (Geneva, CERN) will discussed. The hollow profile electron beam help suppress recombination at the accumulation zone. The low electron beam density at the core of the intensive ion beam decrease the amplitude coherent electron-ion beam oscillations (so called electron heating effect). The electrostatic bending made the recuperation loss electron beam current less then 1 mkA for 1-2 Amp the main electron beam current. Decreasing out gassing by the electrons desorption the vacuum chamber cooler open perspective for obtain the high vacuum at cooler on level 1E-12 Torr (for LEIR cooler)
