    摘要： The present invention discloses an exhaust gas inlet structure of an exhaust gas recirculation (EGR) Cooler which includes a water shell, a gas inlet pipe, a bellow, an insulated pipe, an inlet chamber, a pre-cooling water chamber and a main board. The water shell is equipped with a water inlet pipe. Its main feature is the insulated pipe is placed within the bellow and connected with the gas inlet pipe at one end while the other end is suspended. The large-bore end of the inlet chamber is connected with the main board to form a gas inlet cavity while leaving a space to form a coolant channel between the joining part and the water shell. An external surface of a middle pipe body connects to the bellow to form a pre-cooling cavity connected to the coolant channel. The advantages of the present invention are as follow: newly-added pre-cooling water chamber reduces the wall temperature of the main board and the inlet chamber; newly-added supporting in the middle part of the insulated pipe improves the vibration-proof function of the insulated pipe; the special structure of the inlet chamber increases the ability of the axial displacement compensation. The above-mentioned improvement of the present invention significantly improves the reliability of the EGR cooler.

    摘要： Disclosed is a heat exchanger, particularly an exhaust gas heat exchanger for an internal combustion engine of a motor vehicle, comprising a housing jacket (6) that is open at both ends, and a tube bundle which is inserted into said housing jacket and is penetrated by the hot exhaust gas. The aim of the invention is to produce said heat exchanger in an inexpensive and functionally safe manner. Said aim is achieved by the fact that only the tube bundle with the tube bottoms (2, 3) thereof, which are located on the front side, are made of metal while the housing jacket (6) into which the tube bundle is inserted along with the tube bottoms (23) is made of plastic. The dimensions of the transition between at least the tube bottom that is impinged upon by the hot medium entering the tube bundle on the feeding side are selected in such a way in the direction of the housing jacket that a drop in temperature that is sufficiently great regarding the thermal resistance of the plastic is definitely obtained all the way to the contact area on the housing jacket.

    摘要： In a heat exchanger having a tube bundle comprising a plurality of inner tubes and a plurality of cooling tubes, each of the inner tubes being arranged within each of the cooling tubes and passed therethrough to provide a double tube structure. The inside of the inner cooling tubes are gas tightly connected to both inlet and outlet chambers for high temperature fluid and the outside of the inner cooling tubes are gas-tightly connected to both inlet and outlet compartments for heat transfer medium as open ends, a high pressure lower temperature fluid is passed through the outside of the outer cooling tubes, a fluid having a high thermal conductivity, for example, molten lead, lead alloy, tin, tin alloy bismuth, sodium, salts of mercury or of sodium in a molten state, is passed through the outside of the inner cooling tubes as the heat transfer medium in ordinary case, and a gas having a low thermal conductivity is passed therethrough as a heat transfer medium when the inner tubes are required to be maintained at a high temperature.
