Problems solved by technology
[0002] In the field of petrochemical industry, the air cooler is one of the main equipment for heat dissipation and temperature adjustment in production. In order to solve the positioning problem between the finned tubes, the pressure is often used to press the 3mm×30 wide steel plate into a corrugated plate through the mold, spaced The upper and lower finned tubes play the role of positioning, but because there is no longitudinal positioning, and each heat exchanger needs a lot of corrugated plates, the cost is increased, the quality is not suitable for guarantee, and the operation is complicated

Embodiment Construction
[0005] It includes a positioning bar 1, a finned tube 2, a tube box 3, and an arc-shaped groove 4, and is characterized in that: a finned tube 2 is provided above the positioning bar 1, and a finned tube 2 is provided below the positioning bar 1. The square finned tube 2 is dynamically connected with the arc groove 4 on the described positioning bar 1; The arc grooves 4 are equidistant; the distance L between the arc grooves 4 provided on the top of the positioning bar 1 and the arc grooves 4 is equidistant, The distance K between the arc-shaped groove 4 and the said arc-shaped groove 4 is equal to L / 2. Insert the arc of the lower arc groove of the stamped positioning bar into the fin interval of the lower row of finned tubes, and the upper arc of the positioning bar contacts the bottom of the upper row of finned tubes to play a positioning role. effect. The implementation is convenient and accurate, fast, time-saving and labor-saving, and improves the efficiency.
