Heat exchanger with crossover path for cold fluid distribution

A heat exchanger with a crossover path for cold fluid distribution has a pair of opposing walls and an interior space between the walls, and first and second regions on opposing sides of a longitudinal axis, each region adapted to be in thermal contact with a battery cell. An inlet port and an outlet port are disposed in respective first and second regions, and a flow barrier extends along the longitudinal axis separating the first and second regions. A fluid flow passage is defined in the first region and the second region. The first crossover passage extends across the longitudinal axis from the inlet port to the inlet flow passage in the second region. The second crossover passage extends across the longitudinal axis from the outlet flow passage in the first region to the outlet port. The crossover housing is disposed inside or outside the interior space, and extends across the longitudinal axis, surrounding at least one of the first crossover passage and the second crossover passage. 一种带有用于冷流体分配的跨接通路的热交换器
