Heat exchanger

Abstract

Abstract PURPOSE:To obtain the heat exchanger, prominent in the property of maintenance and compact, by a method wherein heat transfer units, for flowing cooling medium therethrough, are separatably laminated through gaskets while cooling water is made to flow between the neighboring heat transfer untis. CONSTITUTION:In the heat exchanger, the heat transfer units 2, 4a, 4b, laminated through the gaskets 3, are clamped separatably and fixed with each other through through bolts 5, therefore, the heat exchanger is compact and provided with a high resistance to pressure. The refrigerant is supplid from a supplying header 12 and passes through inlet port 7b of respective units 2, 4a, 4b, a main body 7a, an outlet port 7c and a discharging pipe 7e, thereafter, is discharged out of a discharging header 13. Cooling water is supplied to the supplying parts 14a of respective air gap chambers 14 in the gaskets 3 from a supplying pipe 16 through communicating pipes 7e and flows to a discharging section 14b along turbulent flow promoting plates 15 into a direction reverse to the same of the refrigerant, thereafter, passes through communicating pipes 7f and is discharged out of a discharging pipe 17. In this case, heat exchange is effected between the refrigerant and the cooling water. When nuts 5a are removed, respective heat transfer units may be separated and water scale or the like, reserved in the air gap chambers 14, may be removed easily.
