Multi-connected liquid cooling source

The invention relates to a multi-connected liquid cooling source which comprises a compressor, a condenser, an evaporation heat exchange system and a gas-liquid separator which are sequentially connected end to end through pipelines, the evaporation heat exchange system comprises a plurality of evaporation heat exchange branches connected in parallel, and each evaporation heat exchange branch is sequentially provided with a first electromagnetic valve, a throttling device and an evaporator in the flow direction of a heat exchange medium. The throttling device is an electronic expansion valve, a bypass loop is arranged between an outlet of the compressor and an inlet of the evaporator in parallel, and a second electromagnetic valve is arranged on the bypass loop. The temperature control requirements of different loads can be met. 本发明涉及一种多联式液冷源，包括通过管道依次首尾连接的压缩机、冷凝器、蒸发换热系统和气液分离器，蒸发换热系统包括多个并联连接的蒸发换热支路，每个蒸发换热支路上沿换热介质流向依次设有第一电磁阀、节流装置和蒸发器，节流装置为电子膨胀阀，压缩机出口和蒸发器进口之间并联设有旁通回路，旁通回路上设有第二电磁阀。本发明能够满足不同负载的温控需求。
