Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a combined heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials. A heat exchanger is also called a heat exchanger. Some existing heat exchangers have low heat transfer efficiency during use. According to the use requirements, multiple heat exchangers need to be combined for heat exchange;

[0003] After retrieval, in the application document with the patent application number 202221005410.1, a combined heat exchanger is disclosed, which includes a first heat exchanger, a second heat exchanger and a connecting block. The connecting block is fixedly connected to the second heat exchanger. The connecting block penetrates through the first heat exchanger, and the connecting block is slidably connected to the first heat exchanger. A fixing component is arranged on the first heat exchanger. The fixing component includes a grip rod, and a connecting rod is fixedly connected to the outer side of the grip rod. In the utility model, when the connecting block slides, it will squeeze the fixing block to drive the fixing block to move. The fixing block compresses the limit spring through the slider. When the connecting block is completely inserted into the first heat exchanger, the pressure on the limit spring disappears. The limit spring drives the fixing block to reset and insert into the groove of the connecting block through the slider, so as to limit and fix the connecting block. The second heat exchanger and the first heat exchanger can be combined and assembled, so that it is convenient to combine and assemble the heat exchanger during use, and the combination and assembly process is time-saving and labor-saving;

[0004] The above application document realizes the connection and installation between heat exchangers through components such as springs. However, each heat exchanger has a water inlet, an air inlet, an exhaust port and a drain port. Therefore, when installing two heat exchangers, it is necessary to connect each of their ports, and the connection operation is cumbersome, and the connection efficiency is low. Moreover, the entire heat exchanger cannot be disassembled, and the effect is poor.

[0005] Therefore, we propose a combined heat exchanger. Summary of the Utility Model

A liquid pipe extending outward is fixedly connected in the end cylinder. Fifteen sets of annularly distributed air holes are provided on the inner wall of the end cylinder. The air holes are communicated with an air pipe, and a sealing groove is arranged on the outer side of the end cylinder.

[0009] Preferably, the air pipe consists of fifteen sets of arc-shaped regular hexagonal pipes;

[0010] Among them, the arc shape and regular hexagonal shape of the air pipe can increase the contact area and duration between the inner airflow and the outer fluid, ensuring the heat exchange efficiency.

[0011] Preferably, an outer flange is fixedly installed on the outer end side of the end cylinder. A sealing groove is provided at the center of the outer flange, and a sealing plug is sleeved in the sealing groove;

[0012] Among them, the setting of the sealing groove facilitates the gas connection between adjacent heat exchangers, and the setting of the sealing plug can ensure its sealing effect and prevent gas leakage.

[0013] Preferably, the liquid pipe is an L-shaped steel pipe. The outer end of the liquid pipe is a right-angled end, and a sub-flange is fixedly installed on the outer end face of the liquid pipe;

[0014] Among them, the setting of the liquid pipe and the sub-flange can make the adjacent fluids communicate with each other, ensuring the connection efficiency.

[0015] Preferably, an insertion cylinder is fixedly installed inside the end cylinder. The insertion cylinder is clamped inside the end of the heat exchange cylinder, and a sealing ring is filled between the insertion cylinder and the inner side of the end of the heat exchange cylinder;

[0016] Among them, the setting of the insertion cylinder facilitates clamping the end head assembly at the end of the heat exchange cylinder, and the sealing ring ensures the sealing effect at the sleeved part.

[0018] Among them, the setting of the inner flange and the support flange facilitates disassembling and assembling the end head assembly at the end of the heat exchange cylinder, ensuring the assembly effect of the heat exchanger itself.

[0019] The present utility model provides a combined heat exchanger. It has the following beneficial effects:

[0020] The combined heat exchanger, through the setting of the end components at the ends of the heat exchange cylinders, can uniformly transport gas through the connection of the inner flange plates in the end components at the adjacent ends of the heat exchange cylinders during connection. At the same time, the setting of the split flange plates at the ends of the liquid pipes can also uniformly transport liquid, so that there is no need to separately connect the gas and liquid during connection, greatly increasing the combination efficiency. In addition, the trachea can be drawn out of the heat exchange cylinder by disassembling the heat exchange cylinder and the end components, solving the problems that the integral heat exchanger of the existing device is difficult to disassemble and the connection efficiency between adjacent heat exchangers is relatively low.
