Rock fracture flow guide and heat exchange testing device and method

The invention discloses a rock fracture flow guide and heat exchange testing device and method, and belongs to the technical field of deep geothermal resource development. According to the rock crackflow guide heat exchange testing device, a metering pump is arranged on a water supply mechanism; a drainage mechanism is communicated with a water outlet of the crack, and the water outlet of the crack is formed in the top of the rock sample; the detection end of a first temperature sensor is fixedly arranged at a water inlet of the rock sample, the detection end of a second temperature sensor isfixedly arranged at the water outlet of the rock sample, the detection end of a third temperature sensor is arranged in a confining pressure chamber, and the detection ends of a plurality of fourth temperature sensors are arranged on the side wall of the rock sample; the metering pump, the first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensors are all conne
