INFLUENCE OF THE MANIFOLD CONFIGURATION OF PULSATING HEAT PIPES ON THEIR PERFORMANCE
The performance characteristics of three air-to-air pulsating heat pipes with R1233zd as a working fl uid for cooling an electronic cabinet are presented. Each of these pipes comprises two coolers staked in one unit of dimension 36 × 19 × 5 cm3 , constructed with extruded multiport tubes and louvered fi ns brazed together. These pipes differ from each other only in their manifold confi guration achieved by having fl uid distribution plates at the evaporator and condenser manifolds to provide a serial connection of the fl ow paths. The experiments were performed with PHPs of only one type, composed of two coolers in stack and turned through 90o on their narrow side. A new parameter, representing the rate of pressure pulsations in a PHP, was introduced into consideration, and it is shown that this parameter correlates with the PHP performance.
