Abstract
The invention discloses an automobile exhaust gas heat exchanger comprising a housing. An exhaust gas inlet is arranged on one side of the housing, and a qualified exhaust gas inlet is arranged on the other side of the housing. A cover plate is arranged on the top of the housing, a cooling liquid inlet is arranged on one side of the cover plate, and a cooling liquid outlet is arranged on the other side of the cover plate. A transverse heat exchange structure is arranged inside the housing, bending heat exchange tubes are arranged on the upper side and the lower side of the heat exchange structure inside the housing, and each heat exchange tube is provided with a plurality of bending portions. The automobile exhaust gas heat exchanger has the advantages that since automobile exhaust gas containing a mass of harmful objects enters the heat exchange structure and the heat exchange tubes which are perpendicular to each other in space, heat exchange area is increased, and heat exchange rate is high.
Description
Technical field
The present invention relates to a kind of heat exchanger, relate in particular to a kind of automobile exhaust gas heat exchanger.
Background technology
Heat exchanger is to make heat be delivered to cold fluid from hot fluid, it is made of fin and the connection of a plurality of pipe, in the heat exchanger that automobile exhaust gas uses, the condensed water that waste gas produces, has strong corrosiveness, if untimely processing waste gas with influencing the performance of automobile, also can influence air quality.So, be badly in need of a kind of improved technology and solve this problem.
Summary of the invention
The purpose of this invention is to provide the high automobile exhaust gas heat exchanger of a kind of heat transfer rate.
The technical solution used in the present invention is:
The automobile exhaust gas heat exchanger, comprise housing, described housing one side is respectively equipped with exhaust gas inlet, described housing opposite side is respectively equipped with qualified tail gas outlet, and described case top is provided with a cover plate, and described cover plate one side is provided with the cooling fluid inflow entrance, described cover plate opposite side is provided with the cooling fluid flow export, be provided with horizontal heat exchange structure in the described housing, be provided with the bending heat-exchange tube in the housing of both sides about the described horizontal heat exchange structure, has a plurality of kinks on each bending heat-exchange tube.
Described horizontal heat exchange structure comprises a plurality of horizontal heat-exchange tubes and a plurality of shelf, has a horizontal row to heat-exchange tube between per two shelves, and described horizontal heat-exchange tube is spatially vertical mutually with the bending heat-exchange tube.
Described cover plate is fixed on the housing by securing member.
Described cooling fluid inflow entrance and cooling fluid flow export place are equipped with filter membrane.
Beneficial effect of the present invention: automobile exhaust gas contains a large amount of harmful substances, waste gas enters horizontal heat exchange structure and the bending heat-exchange tube in the housing, laterally heat-exchange tube is spatially vertical mutually with the bending heat-exchange tube, can increase heat exchange area, the heat transfer rate height.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, housing, 2, exhaust gas inlet, 3, the outlet of qualified tail gas, 4, cover plate, 5, securing member, 6, the cooling fluid inflow entrance, 7, the cooling fluid flow export, 8, the bending heat-exchange tube, 9, kink, 10, horizontal heat-exchange tube, 11, shelf, 12, filter membrane.
