Description

Technical Field

[0001] This utility model relates to the field of steam oven technology, specifically to a heat exchanger for condensing steam from a steam oven. Background Technology

[0002] Steam ovens have air ducts at the top of the cavity, and then a cooling fan forces air outwards, blowing the gas in the cavity out through the ducts. Because the gas is blown out of the ducts at a high speed, there is little heat dissipation within the ducts. Therefore, when the gas is exhausted outside the machine, the temperature of the exhaust gas is still very high, which can easily cause burns and affect the user experience.

[0003] Chinese patent application No. 202411619143.0, published on February 18, 2025, discloses a gas-liquid partitioning device and a steam oven, which is equipped with a condenser to reduce the heat of the exhaust gas; however, the condenser only exchanges heat with the gas through the gas rack, and as the steam oven continues to exhaust gas, the temperature of the gas rack rises, which causes the condenser to reach temperature saturation, thus reducing the heat exchange efficiency of the condenser. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a heat exchanger for condensing the exhaust gas of a steam oven, wherein a first cooling gas path and a cooling pipe are set up to cool the heat exchanger together, thereby reducing the operating temperature of the heat exchanger and improving the cooling efficiency of the heat exchanger.

[0005] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0006] The present invention discloses a heat exchanger for condensing steam from a steam oven, comprising a partition plate, a first heat dissipation fin on one surface of the partition plate, and a second heat dissipation fin on the other surface of the partition plate. The first heat dissipation fin forms a first cooling air passage, and the second heat dissipation fin forms a second cooling air passage. Cooling pipes are provided on the partition plate to reduce the heat of the heat exchanger.

[0007] Preferably, the inlet of the cooling pipe is connected to a cooling water source, and the outlet of the cooling pipe is connected to the water tank of the steam oven.

[0008] Preferably, the cooling pipes are arranged in a circuitous manner on the partition plate.

[0009] Preferably, the second cooling air path is arranged in a roundabout manner.

[0010] Preferably, the flow direction of the first cooling air path is perpendicular to the flow direction of the cooling pipe.

[0011] Preferably, the cooling pipes are embedded in the partition plate, and the outer wall of the cooling pipes is connected to the first heat sink and the second heat sink.

[0012] Preferably, the partition plate is provided with mounting holes for installing the heat exchanger.

[0013] Preferably, there are multiple first heat sinks, with adjacent first heat sinks spaced apart, and a first cooling air passage is formed between adjacent first heat sinks.

[0014] Preferably, there are multiple second heat sinks, with adjacent second heat sinks spaced apart, and some second heat sinks are staggered along their own length on the partition plate, forming a second cooling air passage between adjacent staggered second heat sinks.

[0015] Compared with the prior art, the beneficial effects of the heat exchanger for condensing exhaust gas from a steam oven described in this utility model are mainly reflected in the following aspects: A second cooling gas path is provided to cool the gas discharged from the steam oven. The gas discharged from the steam oven flows along the second cooling gas path and exchanges heat with the second heat sink, thereby cooling the gas discharged from the steam oven; a first cooling gas path is provided to cool the heat exchanger. External air flows along the first cooling gas path and exchanges heat with the first heat sink, thereby cooling the heat exchanger and improving its cooling efficiency; simultaneously, cooling pipes are provided on the partition plate, and these cooling pipes cool the entire heat exchanger, further reducing the operating temperature of the heat exchanger and further improving its cooling efficiency.

[0016] By connecting the inlet of the cooling pipe to the cooling water source and the outlet of the cooling pipe to the water tank of the steam oven, the cooling water carries away the heat from the heat exchanger as it flows along the cooling pipe and then flows into the water tank of the steam oven, thereby replenishing the water level in the water tank of the steam oven; at the same time, the cooling water absorbs the heat from the heat exchanger, thus heating the cooling water flowing into the water tank, reducing the energy consumption for heating the liquid in the water tank, and shortening the time it takes for the steam oven to generate steam.

[0017] By using a circuitous cooling pipe system, the coverage area of ​​the cooling pipes on the partition plate is increased, thereby improving the cooling effect of the heat exchanger. At the same time, the circuitous second cooling air path increases the flow distance of the exhaust gas from the steam oven within the second cooling air path, increasing the contact area between the gas and the second heat sink, further improving the cooling efficiency of the exhaust gas from the steam oven.

[0018] By setting up a first cooling air path and a cooling pipe with the flow direction perpendicular to each other, the first cooling air path and the cooling pipe are evenly covered in different areas of the heat exchanger, resulting in good cooling uniformity of the heat exchanger.

[0019] By embedding cooling pipes into the partition plate, and through the contact between the cooling pipes and the first and second heat sinks, the cooling effect of the heat exchanger is further improved.

[0020] This invention uses a first cooling air path and a cooling pipe path to cool the heat exchanger together, thereby reducing the operating temperature of the heat exchanger and improving its cooling efficiency. Attached Figure Description

The first heat sink 2 forms a first cooling air passage 4, and the second heat sink 3 forms a second cooling air passage 5. A cooling pipe 6 is provided on the partition plate 1 to reduce the heat of the heat exchanger. An air inlet 11 is provided on the surface of the partition plate 1 near the second heat sink 3. The air inlet 11 is connected to the second cooling air passage 5 and is correspondingly arranged with the exhaust port of the steam oven (not shown in the figure).

[0033] In this embodiment, there are multiple first heat sinks 2, with adjacent first heat sinks 2 spaced apart, and a first cooling air passage is formed between adjacent first heat sinks 2; there are multiple second heat sinks 3, with adjacent second heat sinks 3 spaced apart, and some second heat sinks 3 are staggered along their own length direction on the partition plate 1, and a second cooling air passage 5 is formed between adjacent staggered second heat sinks 3.

[0034] The second cooling air passage 5 is used to cool the gas discharged from the steam oven. The gas discharged from the steam oven flows along the second cooling air passage 5 and exchanges heat with the second heat sink 3, thereby cooling the gas discharged from the steam oven. The first cooling air passage 4 is used to cool the heat exchanger. External air flows along the first cooling air passage 4 and exchanges heat with the first heat sink 2, thereby cooling the heat exchanger and improving the cooling efficiency of the heat exchanger for the gas. At the same time, a cooling pipe 6 is provided on the partition plate 1. The cooling pipe 6 cools the entire heat exchanger, thereby further reducing the operating temperature of the heat exchanger and further improving the cooling efficiency of the heat exchanger.

[0035] Cooling pipe 6 is embedded in partition plate 1, and the outer wall of cooling pipe 6 is connected to the first heat sink 2 and the second heat sink 3.

[0036] The inlet 61 of cooling pipe 6 is connected to a cooling water source (not shown in the figure), and the outlet 62 of cooling pipe 6 is connected to the water tank of the steam oven. By connecting the inlet 61 of cooling pipe 6 to the cooling water source and the outlet 62 of cooling pipe 6 to the water tank of the steam oven, the cooling water carries away the heat from the heat exchanger as it flows along cooling pipe 6 and then flows into the water tank of the steam oven, thereby replenishing the water level in the water tank of the steam oven; at the same time, the cooling water absorbs the heat from the heat exchanger, thus heating the cooling water flowing into the water tank, reducing the energy consumption for heating the liquid in the water tank, and shortening the time it takes for the steam oven to generate steam.

[0037] In a preferred embodiment, refer to Figure 4 As shown, the cooling pipe 6 is arranged in a circuitous manner on the partition plate 1. This circuitous arrangement increases the coverage area of ​​the cooling pipe 6 on the partition plate 1, improving the cooling effect of the heat exchanger. The second cooling air path 5 is also circuitous. This circuitous arrangement increases the flow path of the exhaust gas from the steam oven within the second cooling air path 5, increasing the contact area between the gas and the second heat sink 3, further improving the cooling efficiency of the exhaust gas from the steam oven.

[0038] In a preferred embodiment, the flow direction of the first cooling air passage 4 is perpendicular to the flow direction of the cooling pipe 6. This ensures that the first cooling air passage 4 and the cooling pipe 6 evenly cover different areas of the heat exchanger, resulting in good cooling uniformity.
