Single-tube detachable heat exchanger

Abstract

This invention provides a single-tube detachable heat exchange device, comprising: an outer casing having an exchange space, the exchange space having a first side opening and a second side opening opposite to the first side opening; a first end cap detachably disposed at the first side opening of the outer casing; a second end cap detachably disposed at the second side opening of the outer casing; a heat exchanger unit detachably disposed at the exchange space of the outer casing; and an evaporator unit detachably disposed at the exchange space of the outer casing and adjacent to the heat exchanger unit. Accordingly, the first end cap or the second end cap can be detached as needed to remove and replace the damaged heat exchanger unit or the evaporator unit, thereby reducing maintenance costs and improving maintenance convenience.

Claims

1. A single-tube detachable heat exchange device, comprising: a housing having an exchange space having a first side opening and a second side opening opposite to the first side opening; a first end cap detachably disposed at the first side opening of the housing; a second end cap detachably disposed at the second side opening of the housing; a heat exchanger unit detachably disposed at the exchange space of the housing; and an evaporator unit detachably disposed at the exchange space of the housing and adjacent to the heat exchanger unit.

2. The single-tube detachable heat exchanger as described in claim 1, wherein, The outer casing also has a first assembly portion provided at the first side opening and a second assembly portion provided at the second side opening. The first end cap has a first locking portion that can be detachably provided at the first assembly portion, and the second end cap has a second locking portion that can be detachably provided at the second assembly portion.

3. The single-tube detachable heat exchanger as described in claim 2, wherein, The single-tube detachable heat exchange device also has a first external locking assembly and a second external locking assembly. The first external locking assembly locks the first assembly portion of the outer casing and the first locking portion of the first end cover into one unit. The second external locking assembly locks the second assembly portion of the outer casing and the second locking portion of the second end cover into one unit.

4. The single-tube detachable heat exchanger as described in claim 1, wherein, The outer casing also has a first lockable portion located in the exchange space and adjacent to the first side opening, and a second lockable portion located in the exchange space and adjacent to the second side opening. The heat exchanger unit has a first frame locked to the first lockable portion, and the evaporator unit has a second frame locked to the second lockable portion.

5. The single-tube detachable heat exchanger as described in claim 4, wherein, The single-tube detachable heat exchanger also has a first internal locking assembly and a second internal locking assembly. The first internal locking assembly locks the first locked part of the outer casing and the first frame of the heat exchanger unit into one unit, and the second internal locking assembly locks the second locked part of the outer casing and the second frame of the evaporator unit into one unit.

6. The single-tube detachable heat exchanger as described in claim 4, wherein, The heat exchanger unit also has a plurality of fluid conduits disposed on the first frame and a plurality of first heat dissipation fins disposed on the fluid conduits, and the evaporator unit also has a heat transfer tube disposed on the second frame and a plurality of second heat dissipation fins disposed on the heat transfer tube.

7. The single-tube detachable heat exchange device as described in claim 6, wherein, Each fluid conduit is equipped with interlocking stop sections.

8. The single-tube detachable heat exchanger as described in claim 6, wherein, The heat exchanger unit also has a first filter screen disposed on the first frame and located at one end of each of the fluid conduits, and the evaporator unit also has a second filter screen disposed on the second frame and located on one side of the heat transfer tube.
