No. It takes energy (heat) to evaporate the water that appears on the skin when we sweat. Taking heat away from the body is cooling the body.
A word or two about your statement of something being heated producing salt and water. That isn't true unless salt was in the water initially. And then salt shows up only if enough water is evaporated to produce a saturated solution.
Also, does the relatively high specific heat of water play a part in this? Because it would take large amounts of energy to raise the temperature of the sweat, therefore keeping the sweat cool.
