[0050] The first embodiment of the utility model:

[0051] Because there is a ground rail outside the equipment, in order to meet the heat exchange efficiency, the heat exchanger requires a large power. If the heat exchanger is made into an integral part, when the heat exchanger needs maintenance, it will interfere with the ground rail and cannot be moved out. For the convenience of maintenance, the utility model splits the original entire heat exchanger into two parts, one large and one small (i.e., the upper heat exchanger 3 and the lower heat exchanger 2). The large heat exchanger is installed on the upper part and the small heat exchanger is installed on the lower part. At the same time, the heat exchanger door 1 is also divided into an upper door of the heat exchanger and a lower door of the heat exchanger. The upper door of the heat exchanger is a conventional hinged door, and the lower door of the heat exchanger is fixed to the frame by screws. When maintenance is required, the upper door of the heat exchanger is opened and then the lower door of the heat exchanger is removed. A number of cam followers are respectively installed at the bottom of the two heat exchangers, so that it is convenient to pull in and out. The small heat exchanger is slightly lighter in weight and can be moved in and out after being manually lifted, and the large heat exchanger can be directly pushed in and pulled out with the help of a tool cart.

[0052] The front end of the upper heat exchanger 3 is fixed to the left front upper bracket 5 and the right front upper bracket 6 respectively, and the rear end is fixed to the two rear upper brackets 9 respectively, and then fixed to the left fixing frame 4 through the left front upper bracket 5 and the rear upper bracket 9, and fixed to the right fixing frame 10 through the right front upper bracket 6 and the rear upper bracket 9. Two upper heat exchanger support bars 11 are fixed to the bottom of the upper heat exchanger 3, and the upper heat exchanger support bars 11 are just located on two rows of upper cam followers 12. The left fixing frame 4 and the right fixing frame 10 are each fixed with a series of upper cam followers 12. The upper heat exchanger 3 is fixed with two upper handles 7, so that the upper heat exchanger 3 can be pushed and pulled out through the upper handles 7 under the action of the cam followers 12. The front end of the lower heat exchanger 2 is fixed to the two front lower brackets 8 respectively, and the rear end of the lower heat exchanger 2 is fixed to the two rear lower brackets 13 respectively. The left fixing frame 4 and the right fixing frame 10 are respectively fixed with connecting blocks 15, and the connecting blocks 15 connect the left fixing frame 4 and the rear lower bracket 13, and the connecting blocks 15 connect the right fixing frame 10 and the rear lower bracket 13. Figure 3 It is shown in a fixed state, the left fixing frame 4 and the right fixing frame 10 are respectively fixed to the adapter block 16, a series of lower cam followers 17 are fixed on the adapter block 16, and two lower heat exchanger support bars 18 are fixed to the bottom of the lower heat exchanger 2, and the lower heat exchanger support bars 18 are located on a series of lower cam followers 17.

[0053] There are two latches on the rear fixing block 14, and the rear lower bracket 13 is fixed to the latches on the rear fixing block 14 through the two holes above. When the lower heat exchanger 2 needs to be removed, the fixing screws of the rear lower bracket 13 and the connecting block 15 are loosened, and the latches of the rear fixing block 14 and the rear lower bracket 13 are pulled out. The four rear fixing blocks 14 are rotated 90° to Figure 4 In the state shown, when the front lower bracket 8 has been removed, the lower heat exchanger 2 can be lifted and removed by holding the lower folding handle 19.

[0054] A series of avoidance notches 20 are formed on the left fixing frame 4 and the right fixing frame 10 to avoid the rear upper bracket 9 and the rear lower bracket 13 so that no interference occurs during the removal process.

[0055] In specific applications, the fresh air supplied by the fresh air system 101 enters the heat exchange system 103 through the filtration system 102, and the fresh air is heated. The hot air is then transported to the demand unit through the air outlet B by the fan circulation system 104 for utilization. The utilized air enters the heat exchange system 103 through the return air outlet A and the filtration system 102 to achieve recycling.

[0056] The utility model designs a heat exchanger into two parts, a large part and a small part, and is suitable for a heat exchange system which has obstacles outside the equipment and is inconvenient to load and unload.

[0057] The fixing method is cleverly designed. By opening avoidance grooves on the left and right fixing frames, the heat exchanger can be removed without removing the rear upper bracket and rear lower bracket used to fix the heat exchanger. Disassembly is relatively simple, which can greatly save maintenance costs and work hours.

[0058] Using cam followers to move the heat exchanger instead of slide rails etc. is low cost, easy to maintain and can greatly save space.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
