However, in this device, "the side of the combustion chamber is connected to a heat-conducting element; the heat-conducting element is connected to the ventilation pipe," meaning that heat is transferred at the connection between the heat-conducting element and the ventilation pipe. The limited contact area between the heat-conducting element and the ventilation pipe affects the overall heat exchange efficiency of this device. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a ventilation device for a box-type heat exchanger unit. The heat generated inside the combustion furnace is transferred to the upper vertical heat exchange tube to heat the gas inside the upper vertical heat exchange tube. By designing the upper vertical heat exchange tube to pass through the inside of the combustion furnace, the heat generated inside the heat exchange tube mounting groove is completely wrapped around the outside of the upper vertical heat exchange tube, resulting in a larger contact range and higher heat exchange efficiency.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A ventilation device for a box-type heat exchanger unit includes an outer bearing shell, an upper insulation cover, an upper heat exchange pipe connecting block, auxiliary heat exchange pipes, a combustion furnace, a heat exchange pipe mounting platform, a lower heat exchange pipe connecting block, an upper bearing cover, and heat exchange pipe connecting nuts. The bottom of the outer bearing shell has a combustion furnace mounting platform and a lower heat exchange pipe clearance groove. The combustion furnace mounting platform is centrally located, and the lower heat exchange pipe clearance grooves are evenly arranged around the combustion furnace mounting platform. The combustion furnace is fixedly connected to the top of the combustion furnace mounting platform. One side of the outer bearing shell has a packing port mounting groove, and the other side of the combustion furnace has a packing port. The packing port is inserted into the packing port mounting groove. The combustion furnace is fixed, with a heat exchange tube installation slot in the middle. The number and position of the heat exchange tube installation slots correspond to the lower heat exchange tube clearance slot. The bottom of the combustion furnace has heat exchange tube connecting screws, which are evenly arranged around the heat exchange tube installation slots. The bottom of the combustion furnace is fixedly connected to the heat exchange tube installation platform. The heat exchange tube connecting screws pass through the heat exchange tube installation platform and are threadedly connected to the heat exchange tube connecting nut. The heat exchange tube connecting nut is pressed against the lower part of the heat exchange tube installation platform. The top of the heat exchange tube installation platform has an upper vertical heat exchange tube, which is adapted to the heat exchange tube installation slot and is connected to the heat exchange tube installation slot.

[0006] The upper vertical heat exchange pipe is inserted into the heat exchange pipe mounting groove. The bottom of the heat exchange pipe mounting platform has a lower vertical heat exchange pipe. The lower vertical heat exchange pipe is adapted to the lower heat exchange pipe clearance groove. The lower vertical heat exchange pipe is connected to the lower heat exchange pipe clearance groove. The lower vertical heat exchange pipe is inserted into the lower heat exchange pipe clearance groove. The bottom of the outer bearing shell is fixedly connected to the lower heat exchange pipe connecting block. The top of the lower heat exchange pipe connecting block has a lower heat exchange pipe connecting groove. The lower heat exchange pipe connecting groove is adapted to the lower vertical heat exchange pipe. The lower heat exchange pipe connecting groove is connected to the lower vertical heat exchange pipe. The lower heat exchange pipe connecting groove is sleeved on the outside of the lower vertical heat exchange pipe. One side of the lower heat exchange pipe connecting block has a lower heat exchange pipe, and the other side of the lower heat exchange pipe connecting block has an external heat exchange branch pipe.

[0007] The top of the outer bearing shell is connected to the upper bearing cover. The surface of the upper bearing cover has an upper heat exchange pipe clearance groove. The number and position of the upper heat exchange pipe clearance grooves correspond to the heat exchange pipe installation grooves. The upper heat exchange pipe clearance grooves are adapted to the upper vertical heat exchange pipes.

The bottom of the upper heat exchange pipe connecting block has an upper heat exchange pipe connecting groove. The upper heat exchange pipe connecting groove is adapted to the upper vertical heat exchange pipes and is connected to the upper vertical heat exchange pipes.

[0008] Beneficial effects: 1. When the box-type heat exchanger unit is ventilated, the gas driven by the heat exchange pump flows sequentially through the lower heat exchange tube, the lower heat exchange tube connecting block, the upper vertical heat exchange tube, the upper heat exchange tube connecting block, and the upper heat exchange tube. The heat generated inside the combustion furnace is transferred to the upper vertical heat exchange tube to heat the gas inside the upper vertical heat exchange tube. Through the design of the upper vertical heat exchange tube passing through the inside of the combustion furnace, the heat generated inside the heat exchange tube mounting groove is completely wrapped around the outside of the upper vertical heat exchange tube, resulting in a larger contact area and higher heat exchange efficiency.

[0009] 2. In this utility model, the auxiliary heat exchange tube is sleeved on the outside of the upper exhaust pipe. The high-temperature gas generated by combustion inside the combustion furnace will exchange heat with the auxiliary heat exchange tube when passing through the upper exhaust pipe, thus avoiding the waste caused by the heat not being recovered when the flue gas generated by fuel inside the combustion furnace is discharged from the upper exhaust pipe.

[0010] 3. The upper heat insulation cover of this utility model covers the outside of the upper heat exchange tube connecting block and the auxiliary heat exchange tube. The upper heat insulation cover can protect the upper heat exchange tube connecting block and the auxiliary heat exchange tube, and at the same time, it can also keep the upper heat exchange tube connecting block and the auxiliary heat exchange tube warm, so as to prevent the heat inside the auxiliary heat exchange tube and the upper heat exchange tube connecting block from escaping after the heat exchange is completed, and ensure the subsequent heat exchange effect.
