[0002] As a compact heat exchanger, tube-fin heat exchanger is widely used in the refrigeration industry. With the technological development of the air-conditioning and refrigeration industry, and the further strict control of environmental protection regulations, the requirements for the heat exchange performance of the heat exchange unit itself are more stringent to make up for the poor performance of alternative refrigerants. Therefore, the heat exchanger structure (heat exchange tube and fin type) and the related heat exchanger forming process are important factors affecting the heat exchange performance, which is of great significance to improving the overall heat exchange performance of the heat exchanger.
[0003] When the existing compact tube-fin heat exchanger is in use, the contact time between the heat exchange liquid and the fluid to be heated needs to be improved, and the heat exchange efficiency is low, which is not conducive to the use of the heat exchanger. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a compact tube-fin heat exchanger, which effectively solves the problem that when the existing compact tube-fin heat exchanger is in use, the contact time between the heat exchange liquid and the fluid to be heated needs to be improved, the heat exchange efficiency is low, and it is not conducive to the use of the heat exchanger.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes a shell arranged outside, plugging heads arranged at both ends of the shell, a plurality of tube fins are installed inside the shell, a shunt pipe is installed at one end of the tube fin, a first liquid inlet pipe is arranged in the middle of one side of the shunt pipe, and a confluence pipe is installed at the other end of the tube fin, and also includes a first liquid outlet pipe, an inner cavity, a second liquid inlet pipe, a second liquid outlet pipe and an auxiliary mechanism, the first liquid outlet pipe is arranged in the middle of one side of the confluence pipe, an inner cavity is arranged inside the shell, and an auxiliary mechanism is arranged inside the shell;
[0006] The auxiliary mechanism includes a partition plate, a solenoid valve, a decontamination pipe and a decontamination valve. The partition plate is fixed between the tube fins, a solenoid valve is embedded in the middle of the bottom end of the partition plate, and a decontamination pipe is arranged at the bottom of one side of the shell.
[0007] Preferably, a second liquid inlet pipe is provided in the middle of one side of the shell, and a second liquid outlet pipe is provided in the middle of the other side of the shell.
[0008] Preferably, the top end of the partition plate does not contact the top wall of the shell.
[0009] Preferably, a decontamination valve is installed on the decontamination pipe.
[0010] Preferably, filter screens are installed on both the first liquid inlet pipe and the second liquid inlet pipe.
[0011] Preferably, the ends of the first liquid inlet pipe, the second liquid inlet pipe, the second liquid inlet pipe and the second liquid outlet pipe are all provided with connecting flanges.
[0012] Beneficial effect: When the utility model is used, a partition plate is fixed between each group of tube fins inside the shell, and the partition plate divides the inner cavity into several parts. Since the top of the partition plate does not contact the top wall of the shell, the liquid entering through the second liquid inlet pipe will be sequentially loaded into the partition cavity formed by the partition plate. The liquid entering will not flow directly to the second liquid outlet pipe for discharge, but will exchange heat with the tube fins for a long time in the partition cavity, which is beneficial to the heat exchange use of the heat exchanger. When sewage needs to be discharged, the solenoid valve is opened, and the liquid enters the inner cavity of the shell located at the position of the sewage removal pipe through the solenoid valve. At this time, the sewage discharge operation can be carried out. When discharging sewage, just open the sewage removal valve. The utility model has a novel structure and a clever design. It can increase the heat exchange time, avoid a fast flow rate of the heat exchange liquid, and improve the heat exchange efficiency to a certain extent, which is beneficial to use.
