The invention discloses a double-liquid heat exchange device and aims at providing a heat exchange device which can effectively realize heat exchange between two kinds of liquid, has a temperature difference compensation capacity and can prevent a shell and heat exchange tubes from being damaged due to excessive large temperature difference stress. The double-liquid heat exchange device comprises a tube pass portion, a shell pass portion and a plurality of supports, wherein the tube pass portion comprises a tube pass inlet tube, a tube pass outlet tube and a plurality of heat exchange tubes, the shell pass portion comprises a heat exchanger shell body, a shell pass inlet tube and a shell pass outlet tube, the heat exchanger shell body consists of a seal head, a shell head and a tube box, a fixing tube plate is arranged between the shell head and the tube box, a seal head tube plate is arranged between the seal head and the tube box, a tube pass flow isolating plate divides the internal portion of the shell head into a tube pass flow inlet chamber and a tube pass flow outlet chamber, and an expansion joint is arranged on the tube box. The double-liquid heat exchange device has the beneficial effects that a structural temperature difference compensation effect can be achieved through the characteristic of relatively easy deformation of the position of the expansion joint in combination with the slidable seal head tube plate, and structural damage is prevented from being caused due to excessively large temperature difference stress.
