Central differential heat exchanger and heat exchange performance detection device thereof

The center difference type heat exchanger comprises a heat exchanger body, flow channels are arranged in the heat exchanger body and comprise an inlet flow channel, a second-stage flow channel, a third-stage flow channel, a fourth-stage flow channel and an outlet flow channel, and the two ends of the heat exchanger body are connected with an inlet adapter and an outlet adapter respectively. An inlet pipeline and an outlet pipeline are correspondingly arranged in the inlet adapter and the outlet adapter, the inlet flow channel is communicated with the inlet pipeline, and the outlet flow channel is communicated with the outlet pipeline. According to the invention, two-phase flow heat dissipation has good heat dissipation capability under high-heat flow; the plurality of heat sources have good temperature uniformity; the problems that in the prior art, the heat dissipation capacity under high heat flow is limited, and the temperature uniformity is poor are solved. The invention further discloses a heat exchange
