In this paper, we have studied the thermoenergetic performances of a plate heat exchanger and cross-flow exchanger which is widely used for the mechanical field. The objective of this study and realized a laboratory test bench of (CUBB) and consists of dimensioning the plate heat exchanger and crossed current by two calculation methods, the first with the method of DTLM and The second method of NUT
