Abstract:

A bare tube crossflow heat exchanger and a finned tube crossflow heat exchanger were designed, constructed and tested. The exchangers have sodium as a tube side fluid and air as a shell side fluid and were constructed of inconel. The bare tube heat exchanger has 3 unmixed passes on the sodium side and 1 mixed pass on the air side. The finned tube heat exchanger has 1 unmixed pass on the sodium side and 1 mixed pass on the air side. Both exchangers were designed to have a 10 kw heat exchanger rate at 1500 F, 600 lbh on the sodium side and at 80 F inlet temperature, 200 lbh on the air side. The tests were run from 1 kw to 4 kw at sodium temperatures up to 830 F and sodium flow rates up to 2500 lbh. The inlet air temperatures were about 80 F. The maximum air flow was 220 lbh. The maximum pressure drop on the air side of the bare tube heat exchanger was found to be 0.15 in. of water. The pressure drop on the air side of the finned tube heat exchanger was negligible. The maximum predicted pressure drop in the sodium system was 10 psi in the bare tube heat exchanger and 1 psi in the finned tube heat exchanger. Author
