The technical realization elements of the heat exchanger device of the horizontal condensing unit

Technical realization elements:

3. The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heat exchanger device of a horizontal condensing unit, in which the heat exchanger is bent into three sides in the condenser assembly and the back baffle is fixed to form a cavity , And set up a single cooling fan in the cavity, only need a single cooling fan to realize heat exchange, and it uses the heat exchanger to bend on three sides and fix the back baffle to form a cavity so that the installation position does not need to be too long or too wide Therefore, while increasing the heat exchange area, the volume of the entire condenser assembly is ensured, and the space occupation is reduced.

4. The solution of the utility model to solve the technical problem is:

5. A heat exchanger device of a horizontal condensing unit, comprising a bottom mounting frame, and a condenser assembly is fixed on the left top surface of the bottom mounting frame;

6. The condenser assembly includes a cooling fan and a heat exchanger;

7. The heat exchanger is bent to form three heat exchange wall parts, the rear part of the heat exchange wall part on the left side and the heat exchange wall part on the right side are fixed on the rear baffle, and the heat exchanger The bottom surface is fixed with a bottom plate, the top surface of the heat exchanger is fixed with an upper cover plate, the upper cover plate covers the top of the cavity formed by the heat exchanger and the back baffle, and the bottom plate covers the cavity formed by the heat exchanger and the back baffle A heat dissipation fan is installed on the upper cover plate at the bottom of the, and the heat dissipation fan is in the cavity;

8. An air outlet through hole is formed in the middle of the bottom plate, and the air outlet through hole faces the impeller of the heat dissipation fan.

9. The bottom mounting frame includes two horizontal connecting rods that are parallel to each other. The left parts of the two horizontal connecting rods are provided with two mounting connecting rods extending back and forth. The ends of the mounting connecting rods are fixed on the corresponding transverse connecting rods. Top surface

10. The bottom plate is fixed on the top surface of the two installation connecting rods.

11. The outer side walls of the heat exchange wall part on the left side and the right heat exchange wall part of the heat exchanger are both provided with side vertical connecting rods, and the bottom ends of the side vertical connecting rods are formed with bottom folds. The bent part, the bottom bent part is fixed on the left or right bottom surface of the bottom plate, the top of the side vertical connecting rod is formed with an upper bent part, and the upper bent part is fixed on the left or right top of the upper cover plate On the surface, the upper horizontal mounting plate is fixed on the two upper bending parts, and the top end of the connecting bolt of the motor of the heat dissipation fan extends from the top surface of the upper cover plate and is fixed on the upper horizontal mounting plate.

12. The cooling fan is a centrifugal fan.

13. The three heat exchange wall panels are formed into a zi shape, and an arc-shaped bend is formed between the left heat exchange wall part and the right heat exchange wall part and the front heat exchange wall part. Transition department.

14. The heat exchanger is a microchannel heat exchanger, which is composed of a first header, a second header, and a plurality of microchannel flat tubes, and one end of all the microchannel flat tubes is fixed to the first header The other end of all the micro-channel flat tubes is fixed on the side wall of the second collecting tube on the side wall of the micro-channel. A wavy-bent radiating fin is provided between two adjacent micro-channel flat tubes, and the radiating fins are welded Fixed on the opposite wall surfaces of two adjacent microchannel flat tubes, a plurality of microchannel through holes are formed in the middle of the microchannel flat tubes, and the microchannel through holes are connected with the inner cavities of the first collector and the second collector. Communicate

15. The inner middle of the first header is provided with a partition, and the side wall of the partition is fixed on the inner side wall of the middle of the first header and divides the first header into a first cavity and a second Two cavities, one end of one half of the microchannel flat tube communicates with the first cavity, one end of the other half of the microchannel flat tube communicates with the second cavity, and the first cavity is connected to the side wall of the first header There is a discharge pipe, and the side wall of the first header at the second cavity is connected with a feed pipe.

16. The outstanding effects of this utility model are:

17. Compared with the prior art, its condenser assembly bends the heat exchanger into three sides and fixes the back baffle to form a cavity, and a single heat dissipation fan is arranged in the cavity, which can be realized by only a single heat dissipation fan. Heat exchange, and it uses the heat exchanger to be bent on three sides and fixes the back baffle to form a cavity so that the installation position does not need to be too long or too wide, thereby increasing the heat exchange area while ensuring the volume of the entire condenser assembly and reducing Space occupation.
