Abstract
Claims
1. A heat exchanger, comprising a shell (1) and a tube bundle (5) disposed within the shell (1), wherein a baffle plate (8) is also disposed within the shell (1) at a position corresponding to the tube bundle (5), a support (3) and an inlet pipe (2) are disposed above the shell (1), and a compensation ring (6) and a drain pipe (4) are disposed below the shell (1), wherein at least two supports (3) are evenly disposed along the circumference of the shell (1), characterized in that: The housing (1) is provided with a protective mechanism (7) at the position corresponding to the compensation ring (6). The protective mechanism (7) includes a positioning ring (9) sleeved on the housing (1). Two positioning rings (9) are provided above and below the compensation ring (6). There is a receiving gap between the two positioning rings (9) for accommodating the compensation ring (6). The positioning ring (9) is coaxially arranged with the housing (1). The two positioning rings (9) are connected by a connector (10). At least three connectors (10) are evenly arranged along the circumference of the positioning ring (9). Each connector (10) is provided with a plug-in part (11) above and below. The outer diameter of the plug-in part (11) is smaller than the outer diameter of the connector (10). The positioning ring (9) is provided with a plug-in hole (19) that cooperates with the plug-in part (11).
2. A heat exchanger according to claim 1, characterised in that: The positioning ring (9) includes a left half ring and a right half ring, which are connected by a connecting bolt (16).
3. A heat exchanger according to claim 2, wherein: Both the left and right halves of the ring are provided with fitting parts (14) that can fit with the surface of the housing (1). The fitting parts (14) are vertically set on the corresponding left or right halves of the ring. Each fitting part (14) has one end fixed on the left or right halves of the ring and the other end pressing against the housing (1).
4. A heat exchanger according to claim 3, wherein: The housing (1) is provided with a positioning groove (17) that mates with the fitting (14).
5. A heat exchanger according to any one of claims 2-4, characterised in that: Both the left and right half-rings are provided with anti-slip pads (15) on the side facing the housing (1).
6. A heat exchanger according to claim 1, wherein: The accommodating gap is provided with a filler (13), and the filler (13) is provided with an accommodating groove that cooperates with the compensation ring (6).
7. A heat exchanger as claimed in claim 1, wherein: The connector (10) is an arc-shaped plate structure, with the inner arc surface of the connector (10) facing the shell (1).
8. A heat exchanger according to claim 1 or 7, characterised in that: The plug-in part (11) has a detachable limiting member (12) at one end that passes through the plug-in hole (19).
