[0002] With the rapid development of modern kitchen appliances, steam ovens, as a composite cooking device integrating steaming and baking functions, are gradually becoming an important part of family kitchens. By combining the functions of a traditional steamer and an oven, steam ovens can meet diverse cooking needs, such as steaming fish, baking bread, and baking cakes. Their working principle mainly relies on internal heating elements generating high temperatures and a steam generator producing steam to heat and cook food. Currently, most steam ovens on the market use electronic control systems to precisely adjust temperature and time, and are equipped with various preset programs to meet the cooking requirements of different ingredients. However, in actual use, users have gradually discovered some shortcomings in most steam ovens on the market: the internal environment of a steam oven is constantly exposed to a harsh high-temperature and high-humidity environment, which poses a serious challenge to the temperature resistance and long-term reliability of the internal electronic components.

[0026] like Figure 1 and Figure 2 As shown, the heat dissipation device provided by this utility model includes: a refrigeration system, a refrigeration housing 109, a cold air fan 106, and a cold air outlet duct.

[0027] The refrigeration system includes a condenser 104, an evaporator 116, and a refrigerant, which circulates between the condenser 104 and the evaporator 116. The refrigeration system also includes a compressor 103 and a throttling device. The compressor 103 is located between the condenser 104 and the evaporator 116, forming a high-pressure gaseous refrigerant and delivering it to the condenser 104. The throttling device is located downstream of the condenser 104; the high-pressure liquid refrigerant flows through the throttling device, is reduced in pressure, and becomes a low-pressure liquid refrigerant before entering the evaporator 116.

[0028] A cooling housing 109 covers the outside of the fins of the evaporator 116, and the cooling housing 109 has a first air inlet and a first air outlet that communicate with each other. The air outlet of the cooling fan 106 is connected to the first air inlet. The inlet of the cooling air outlet duct is connected to the first air outlet, and the cooling air outlet duct has an exhaust port facing the air to be cooled. Through the above structure, a cold airflow is formed by the external environment flowing through the evaporator 116 and being cooled, and the cold airflow is then directed towards the electronic devices to be cooled.

[0029] The air duct for cold air outlet includes a first pipe 110, a pressure valve 111, a second pipe 112, and an air guide mechanism 113. One end of the first pipe 110 is connected to the first air outlet, and the other end is connected to one end of the pressure valve 111. The other end of the pressure valve 111 is connected to one end of the second pipe 112, and the other end of the second pipe 112 is connected to the air guide mechanism 113. The exhaust port is located on the air guide mechanism 113. The pressure valve 111 is used to form a jet airflow, thereby accelerating the gas flow and making the discharged cold air jet farther and cover more devices.

[0030] The heat dissipation device includes a first air guide shroud 201, which includes a first port and a second port, and a first air duct connecting the first port and the second port. The area of ​​the first port is smaller than that of the second port, and the first air duct gradually thickens from the first port to the second port. The air outlet of the air cooler 106 is connected to the first port, and the first air inlet is connected to the second port.

[0031] The horn-shaped first air guide shroud 201 allows the airflow generated by the air cooler fan 106 to be directed towards the evaporator 116 inside the first air guide shroud 201, and to be evenly distributed with the fins on the evaporator 116, thereby improving heat exchange efficiency.

[0032] The heat dissipation device includes a second air guide shroud 202, which includes a third port and a fourth port, and a second air duct connecting the third port and the fourth port. The area of ​​the third port is larger than that of the fourth port, and the second air duct gradually narrows from the third port to the fourth port. A first air outlet is connected to the third port. The inlet of the cold air outlet air duct is connected to the fourth port.

[0033] The trumpet-shaped second air guide shroud 202 collects the airflow after heat exchange, and the cold air flows out from the fourth port and enters the cold air outlet duct.

[0034] The specific process is as follows: When the unit is operating, the refrigerant, driven by the compressor 103, forms a high-pressure gaseous refrigerant and is delivered to the condenser 104. The high-pressure gaseous refrigerant condenses and releases heat in the condenser 104, transforming into a high-pressure liquid refrigerant. Subsequently, this high-pressure liquid refrigerant flows through a throttling device, where it is reduced in pressure and transformed into a low-pressure liquid refrigerant, which then enters the evaporator 116. The low-pressure liquid refrigerant evaporates and absorbs heat within the evaporator 116, absorbing heat from the surrounding ambient air and thus lowering its temperature. Simultaneously, the air cooler fan 106 starts, generating airflow. This airflow passes through the first air guide shroud 201 and enters the refrigeration casing 109, contacting the fins of the evaporator 116 and exchanging heat with it, thus being cooled to form a low-temperature airflow. This low-temperature airflow is guided to the pressure valve 111 via the first pipe 110. Under the action of the pressure valve 111, the low-temperature airflow is pressurized, forming a low-temperature jet. The cryogenic jet is delivered to the air guide mechanism 113 via the second pipe 112. The air guide mechanism 113 directs the cryogenic jet to the electronic component area located above the main unit. Through forced convection heat exchange between the cryogenic jet and the electronic components, the operating temperature of the electronic components is effectively reduced, and their temperature rise is suppressed, thereby significantly improving the reliability and service life of the electronic components.

[0035] The heat dissipation device also includes: a heating cover 105, a hot air fan 108, and a hot air outlet duct. The heating cover 105 is installed on the outside of the fins of the condenser 104. The heating cover 105 is provided with a second air inlet and a second air outlet that are connected to each other. The air outlet of the hot air fan 108 is connected to the second air inlet. The inlet of the hot air outlet duct is connected to the second air outlet, and the outlet of the hot air outlet duct is connected to the interior of the cooking cavity 300 of the cooking equipment.

[0036] The heat emitted by the condenser 104 is concentrated inside the heating shell 105. Under the action of the hot air fan 108, outside air can enter the heating shell 105 and exchange heat with the condenser 104, thereby forming a hot airflow. This hot airflow is then introduced into the cooking cavity 300 through the hot air outlet duct to cook the food in the cooking cavity 300 at a low temperature.

[0037] The hot air outlet duct includes a third pipe 115, an electric valve 102, and a fourth pipe 205. One end of the third pipe 115 is connected to the second air outlet, and the other end is connected to one end of the electric valve 102. The other end of the electric valve 102 is connected to one end of the fourth pipe 205, and the other end of the fourth pipe 205 is connected to the cooking cavity 300. The electric valve 102 is used to open or close the hot air outlet duct, allowing hot air to enter the cooking cavity 300 when necessary. Furthermore, the electric valve 102 is a high-pressure electric valve, which can increase the airflow speed. Under the action of the high-pressure electric valve 102, the flow rate of the hot air is accelerated, forming a high-temperature, high-pressure hot air jet.

[0038] The heat dissipation device also includes an auxiliary fan 101, the outlet of which is connected to a fourth pipe 205 to propel the airflow from the electric valve 102 into the cooking chamber 300, thereby increasing the airflow velocity. The auxiliary fan 101 is connected to the fourth pipe 205 via a reducing pipe 204, wherein the reducing pipe 204 has a larger connection port to the auxiliary fan 101 and a smaller connection port to the fourth pipe 205.

[0039] The heat dissipation device includes a third air guide shroud 206, which includes a fifth port and a sixth port, and a third air duct connecting the fifth port and the sixth port. The area of ​​the fifth port is smaller than that of the sixth port, and the third air duct gradually thickens from the fifth port to the sixth port. The air outlet of the hot air fan 108 is connected to the fifth port, and the second air inlet is connected to the sixth port.

[0040] The horn-shaped third air guide shroud 206 allows the airflow generated by the hot air blower 108 to be directed towards the condenser 104 inside the third air guide shroud 206, and to be evenly distributed with the fins on the condenser 104, thereby improving heat exchange efficiency.

[0041] The heat dissipation device includes a fourth air guide shroud 208, which includes a seventh port and an eighth port, and a fourth air duct connecting the seventh port and the eighth port. The area of ​​the seventh port is larger than that of the eighth port, and the fourth air duct gradually narrows from the seventh port to the eighth port. A second air outlet is connected to the seventh port. The inlet of the hot air outlet air duct is connected to the eighth port.

[0042] The trumpet-shaped fourth air guide shroud 208 collects the airflow after heat exchange, and the hot air flows out from the eighth port and enters the heat-contact chamber.

[0043] The specific workflow is as follows: Driven by compressor 103, the refrigerant forms a high-pressure gaseous refrigerant and is transported to condenser 104. In condenser 104, the high-pressure gaseous refrigerant undergoes a condensation phase change, releasing heat and transforming into a high-pressure liquid refrigerant. Simultaneously, hot air fan 108 starts, generating airflow. This airflow passes through the third air guide shroud 206 and enters the heating shroud 105. As the airflow passes through the fins of condenser 104, it exchanges heat with the condenser, absorbing the heat released during condensation, thus being heated to form a hot airflow with a temperature range of approximately 50°C to 60°C. This hot airflow, approximately 50°C to 60°C, is guided to high-pressure electric valve 102 via fourth pipe 205. Under the action of high-pressure electric valve 102, the flow rate of the hot airflow is accelerated, forming a high-temperature, high-pressure hot air jet. This high-temperature, high-pressure hot air jet is injected into the cooking cavity 300 of a cooking appliance (e.g., a steam oven). The heating fan 117 in the cooking equipment operates simultaneously, driving forced convection of air within the cooking chamber 300 to ensure uniform temperature distribution within the chamber. By precisely controlling the temperature of the hot air jet within the range of approximately 50°C to 60°C (preferably below 60°C), combined with the forced convection effect of the heating fan 117, low-temperature cooking of food within the chamber is achieved. In this precisely controlled low-temperature environment (approximately 50°C to 60°C), and maintaining sufficient cooking time, the connective tissue in food (especially meat) is effectively softened. Simultaneously, by controlling the temperature below the point of significant muscle fiber contraction (typically 60°C to 65°C), excessive muscle fiber contraction is maximally suppressed. This significantly reduces the loss of juices (moisture), ensuring that cooked food (such as meat) achieves an exceptionally tender and juicy texture.

[0044] Secondly, the cooking equipment provided by this utility model includes the aforementioned heat dissipation device. Because the cooking equipment provided by this utility model incorporates the aforementioned heat dissipation device, it also possesses the advantages of a heat dissipation device.
