Technical field
The utility model relates to heat exchange equipment technical field, especially a kind of structure of plate-fin core body.
Background technology
Heat exchanger, also known as heat exchanger, passes to the device of another kind of heat-carrying agent from a kind of heat-carrying agent by heat.In industrial processes, usually need to carry out heating or cooling, i.e. the transmission of heat.When a kind of fluid and one other fluid carry out heat exchange and do not allow to mix, just requiring to carry out in recuperative heat exchanger, be applied to the industries such as chemical industry, oil, power, food. the Main Function of heat exchanger is thermal energy exchange between cold fluid and hot fluid.
In plate-fin heat exchanger production process, the mode of Welding is adopted to connect between each parts, welded and installed end socket is wanted at fin heat exchanger core two ends, but existing heat exchanger core body coordinates not tight with end socket, there is low, the yielding problems of crack of intensity.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of fin heat exchanger core structure rational in infrastructure, thus facilitates the welded and installed of heat exchanger core body and two ends end socket, ensures weld strength.
The technical scheme that the utility model adopts is as follows:
A kind of fin heat exchanger core structure, comprise the symmetrical cover plate installed up and down, between described cover plate, multiple heat exchanger channels is installed, the structure of described heat exchanger channels is: the first composite plate comprising the adjacent installation with cover plate, first composite plate parallel interval is provided with the second composite plate, the fin of evenly arranging is installed between described first composite plate and the second composite plate; Second composite plate parallel interval is provided with the 3rd composite plate, and the first strip of paper used for sealing is installed at described fin two ends respectively, and be alternately arranged formation heat exchanger channels successively; The second strip of paper used for sealing of structure of right angle tyoe is installed at the two ends being positioned at the fin at cover plate place respectively, and described second seal structure is: the head of described second strip of paper used for sealing right-angle side is provided with chamfering, and described chamfering is corresponding with the structure of end socket connecting portion; Be positioned at chamfering opposite face and be formed with " L " type right angle platform, the vertical edge of described right angle platform coordinates with cover plate end face and the first composite plate end face simultaneously, and the horizontal sides of described right angle platform matches with the bottom surface of the first composite plate; Described right angle platform is extended with vertical edges downwards, and described vertical edges connects fin; The bottom surface of described second strip of paper used for sealing coordinates with the second composite plate and abuts.
Further improvement as technique scheme:
