The invention discloses a compact condensing evaporator, which comprises a shell, a low-temperature circulating air inlet pipe and a low-temperature circulating liquid outlet pipe arranged on the shell. The shell is provided with two covers, in the cavity formed by the two covers, a plurality of heat exchange plates arranged at intervals and sleeved on a relatively arranged high-temperature circulating air outlet pipe and a high-temperature circulating liquid inlet pipe are arranged obliquely, and the peripheral surface of the heat exchange plate is adjacent to the heat exchange plate In addition to the reserved and medium flowing gap between the upper and lower ends and the inner wall of the shell, the upper and lower ends are sealed and connected with the inner wall of the shell; the two ends of the high-temperature circulating air outlet pipe and the high-temperature circulating liquid inlet pipe are installed in the holes of the two covers and extend out of the cover, and the outer side of the cover on the side of the low-temperature circulating air inlet pipe is provided with a cover. The invention uses the inclined heat exchange plate to increase the disturbance of the working medium, at the same time, the structure is compact, the filling amount of the refrigeration working medium is reduced, the high-efficiency heat transfer of the condensation evaporation process of the high and low temperature circulating working medium is solved, and the performance of the refrigeration system is improved.
