Abstract
Abstract A heat exchanger apparatus has a hot-fluid casing (l) and a cold-fluid casing (2) which are separated from each other by a partitioning plate (3) and through which a fluid of a higher temperature (l8) and a fluid of a lower temperature (l9) pass, respectively. The hot-fluid casing (l) accommodates a plurality of heat transfer tubes (5) charged with a heat medium and connected at their ends to respective headers (4, 7) so as to constitute an evaporator panel (P₁). The cold-fluid casing (2) also accommodates a plurality of heat transfer tubes (9) similar to that in the hot-fluid casing (l) and connected at their ends to respective headers (ll, 8) so as to constitute a condenser panel (P₂). The header (7) on the medium outlet side of the evaporator panel (P₁) and the header (ll) on the medium inlet side of the condenser panel (P₂) are positioned substantially at the same level. The header (8) on the medium outlet side of the condenser panel (P₂) is disposed above the header (4) on the medium inlet side of the evaporator panel (P₁) and these headers (8, 4) are connected to each other through a connection pipe (l3).

Claim 1
Independent Claim
204 words
A heat exchange apparatus comprising: a hot-fluid casing (l) through which a fluid of a higher temperature passes; a cold-fluid casing (2) disposed adjacent to said hot-fluid casing, through which a fluid of a lower temperature passes; partition means (3) for separating said casings; condenser tube groups (P2) disposed in said cold-fluid casing (2) and constituted by a plurality of heat transfer tubes (9) each charged with a heat medium, said heat transfer tubes (9) being connected at one end thereof to a condenser inlet header (ll) and at the other end thereof to a condenser outlet header (8); evaporator tube groups (P₁) disposed in said hot-fluid casing (l) and constituted by a plurality of heat transfer tubes (5) each charged with a heat medium, said heat transfer tubes (5) being connected at one end thereof to an evaporator inlet header (4) and at the other end thereof to an evaporator outlet header (7), and said heat transfer tubes (5) extending inclined to a direction of the force of gravity; and connection pipes (l3; l2, l3) through which said condenser tube groups and said evaporator tube groups are connected to each other for allowing said heat medium to be circulated through said tube groups.
Claim 2
Dependent Claim
204 words
A heat exchange apparatus comprising: a hot-fluid casing (l) through which a fluid of a higher temperature passes; a cold-fluid casing (2) disposed adjacent to said hot-fluid casing, through which a fluid of a lower temperature passes; partition means (3) for separating said casings; condenser tube groups (P2) disposed in said cold-fluid casing (2) and constituted by a plurality of heat transfer tubes (9) each charged with a heat medium, said heat transfer tubes (9) being connected at one end thereof to a condenser inlet header (ll) and at the other end thereof to a condenser outlet header (8); evaporator tube groups (P₁) disposed in said hot-fluid casing (l) and constituted by a plurality of heat transfer tubes (5) each charged with a heat medium, said heat transfer tubes (5) being connected at one end thereof to an evaporator inlet header (4) and at the other end thereof to an evaporator outlet header (7), and said heat transfer tubes (5) extending inclined to a direction of the force of gravity; and connection pipes (l3; l2, l3) through which said condenser tube groups and said evaporator tube groups are connected to each other for allowing said heat medium to be circulated through said tube groups.
