The casing 14 is formed so that the flanges 15 on both end faces are line symmetrical with respect to the center line O that extends in the direction perpendicular to the flow path direction at the center of the casing 14 (l 1 = l 2 ). . Each of the above end flanges 15,
15 is bolted to the drainage main;
One end flange 15 is integrally formed with an insertion cylinder portion 16 that is inserted into the drainage main pipe. A horseshoe-shaped heat exchange chamber 17 is formed in the center of the casing 14 so as to surround the flow path A, and a large number of heat exchanger tubes 18 are arranged within the heat exchange chamber 17, with both ends of each heat exchanger tube 18 being disposed in the heat exchange chamber 17. is inserted into the circular arc hole 20 of the pair of extending walls 19, 19 of the casing 14. An arcuate mounting plate 21 that closes the arcuate hole 20 is fixed with bolts 22 to the outer surface of the pair of extension walls 19, 19, and both ends of each heat transfer tube 18 are inserted into a large number of through holes formed in each of the mounting plates 21. ing. Furthermore, each mounting plate 2
A mounting ring 23 with an O-ring is provided which fits into the through hole of 1 and fits externally to each heat transfer tube 18. The mounting ring 23 is provided with an inner collar that corresponds to the end surface of each heat transfer tube 18 to prevent each mounting ring 23 from moving into the casing 14. A collecting pipe cover 24 having a semicircular cross section and communicating with each heat transfer tube 18 is fixed to each of the mounting plates 21 with bolts 25, and the inside of the collecting pipe cover 24 is partitioned at appropriate intervals with partition plates 26, and the collecting pipe covers 24 are separated from each other by partition plates 26. are communicated through a communication tube 27, thereby forming a series of zigzag heat transfer channels. An inlet pipe 28 and an outlet pipe 29 are connected to the inlet and outlet of the heat transfer channel, and the inlet pipe 28 and outlet pipe 29 are further connected to the cylinder cooling system of the engine for driving the drainage pump. The collecting pipe cover 24 also has the function of preventing the attachment ring 23 from coming off. The stay 31 of the leg 30 provided at the lower part of the casing 14 is connected to a pair of extending walls 19,1.
The upper portion 31a (between α) of the stay 31 has a wall thickness of β, and the outer surface of the upper portion 31a is flush with the outer surfaces of the pair of extending walls 19, 19. With this, it becomes possible to lower the lower ends of the mounting plate 21 and the collecting pipe cover 24, and the circular arc hole 20 of the casing 14 can also be enlarged, and the number of heat exchanger tubes 18 inserted into the circular arc hole 20 can be reduced to 1. It is possible to increase the number of rows (four rows in total). Furthermore, the leg 30 itself is reinforced by the upper portion 31a of the stay 31 having a wall thickness β.

ン形熱交換器。[Scope of Claims] 1. An in-line type that is connected to the middle of the discharge piping of an engine-driven drainage pump and has a flow path formed therein that allows fluid in the discharge piping that has flowed from one side to flow into the other discharge piping. In the heat exchanger, the casing of the heat exchanger is integrally formed in a cylindrical shape, and a pair of extending walls extending radially outward are spaced apart from each other by a predetermined distance in the axial direction on the outer periphery of the axially central portion of the casing. A closed wall is integrally formed between the tip portions of the pair of extending walls,
A heat exchange chamber communicating with the flow path is provided inside, and a pair of holes for inserting the heat exchanger tubes are formed in the pair of extending walls, penetrating in the axial direction, and the heat exchanger tubes are inserted into the pair of holes. The heat exchanger tube is placed horizontally between a pair of extending walls with both ends disposed, and the end portion of the heat exchanger tube is installed horizontally between the pair of extending walls on each outer surface of the pair of extending walls. An in-line heat exchanger characterized in that a collector pipe cover communicating with an opening of the in-line heat exchanger is removably provided.
