[0019] The utility model discloses a quick cooling large capacity air conveying baking oven, combines Figures 1 to 4As shown, it comprises an oven body 1, a cold water machine 2, a condenser 3 and a circulating fan 4. The condenser 3 comprises a cooling chamber. The water outlet pipe 20 and the water return pipe 21 of the cold water machine 2 are respectively communicated with the heat exchange pipe in the cooling chamber. The cold water machine 2 is used to drive the cold water to circulate along the water outlet pipe 20, the water return pipe 21 and the heat exchange pipe. The air inlet of the circulating fan 4 is communicated with one side of the baking chamber of the oven body 1 through the air inlet pipe 40. The air outlet of the circulating fan 4 is communicated with the other side of the baking chamber of the oven body 1 through the air outlet pipe 41. The circulating fan 4 is used to drive the airflow to circulate along the air inlet pipe 40, the air outlet pipe 41 and the oven body 1.

[0020] In the above structure, the baking chamber of the oven body 1 is provided with a plurality of baking shelves 11. The batteries to be baked are placed on the baking shelves 11 layer by layer. Then the oven door is closed and the oven body 1 enters the baking mode. After baking is completed, the cold water machine 2 and the circulating fan 4 are powered on. When the cold water machine 2 works, it drives the cold water to circulate along the water outlet pipe 20, the water return pipe 21 and the heat exchange pipe. The heat exchange pipe exchanges heat with the air in the cooling chamber of the condenser 3. During the operation of the circulating fan 4, it drives the airflow to circulate along the air inlet pipe 40, the air outlet pipe 41 and the oven body 1. Thus, the hot air is sucked into the cooling chamber of the condenser 3, and the airflow cooled in the cooling chamber is delivered to the oven body 1.

[0028] In the above structure, the battery placing plate 12 is used for carrying batteries, and when the batteries are loaded, the batteries are aligned with the middle positions of the plurality of battery blocking strips 13, and under the guiding action of the inclined portion 14, the batteries can avoid interfering with the top end of the battery blocking strip 13, thereby smoothly entering between the plurality of battery blocking strips 13. Under the surrounding action of the plurality of battery blocking strips 13, the battery can be peripherally limited and hollow space can be provided, so that the battery can be fully heated and the baking effect is better.
