摘要： PURPOSE: To increase the heat exchanging efficiency of the titled heat exchanger by making the transfer of heat easy by filling the gaps between fins and a tube with heat transferrable pulverized powder being mixed with setting agent, in a heat exchanger in which a plurality of fins and a tube which piercing through the holes of fins are bonded in a body by a tube expanding work.
CONSTITUTION: When this heat exchanger is applied to a radiator for a car, a tube 1 of aluminum alloy is inserted and fixed in the holes 2a of a plurality of fins 2 made of aluminum material. The inner diameter of the hole 2a of a fin 2 is 0.3W0.4mm larger than the outer diameter of a tube 1 before being fixed in the hole. The tube 1 is expanded by piercing a tube-expanding tool through the tube 1 after it is inserted into the holes 2a, and it is fixed in the holes 2a of fins 2 by contacting it to a collar 2b which is provided to the inner perimeter of holes 2a. Before the tube 1 is inserted into the holes 2a of fins 2, a mixture of pulverized powder of scaly aluminum, an adhesive and solvent ethyle cellosolve are coated about T=0.1μm thick on the external surface 5 of a tube 1 as a heat transferrable pulverized powder.

摘要： PURPOSE:To separate a packing from cooling water to prevent the packing from swelling by disposing a subplate on the upper surface of the packing and setting the inner diameter of the collar hole of the packing smaller than the inner diameter of the collar hole of the subplate by a predetermined amount in a prior state of tube expansion. CONSTITUTION:In the titled solderless type heat exchanger, a header plate 5, a packing 8, and a subplate 6 have collar holes 5a, 8a and 6a, respectively. The positions of respective collar holes 5a, 8a and 6a are aligned, and the end portion 1a of the tube 1 is inserted therethrough, and the tube 1 is expanded, whereby the tube 1, the header plate 5, the packing 8, and the subplate 6 are mutually secured to each other. In the prior state of the tube expansion, the inner diameter of the collar hole 8a is set smaller than that of the collar hole 6a. As a result, at the time of the tube opening expansion, the subplate 6 functions as a guide, and a packing 8b around the tube 1 is compressed uniformly. Hence, a stable bonding strength is obtained. In addition, since the packing is separated from cooling water by the subplate 6, the packing swells and there is no possibility of causing the leakage of cooling water and corrosion of the tube 1.
