Description

Technical field:

[0001] The utility model relates to the technical field of heat exchanger equipment, and more specifically to an evaporation structure of a refrigeration system for a steam box. Background technology:

[0002] The current steamer generally allows steam to enter the box body to steam the materials placed inside. However, the function of the existing steamer is only to steam the materials, and after steaming, the food is not taken out directly, but left inside. After a long time, the food will deteriorate, affecting its edibility;

[0003] Similarly, some steamers also have a reservation function, which requires that the ingredients be placed in the box in advance and steamed at a set time. In summer, if the ingredients are placed in the box in the morning and steamed in the evening, and since the box is closed and the weather is hot in summer, the ingredients in the box may have deteriorated at noon. When they are steamed in the evening, the taste of the ingredients has changed, affecting consumption. Therefore, it is necessary to install a refrigeration coil in the steamer, which can fix a cooling coil for circulating refrigerant on the inner wall of the box, connect the cooling coil with an external refrigeration system, and use it as an evaporator to cool down. However, in the existing steamer, in order to place more pans, support strips are set on the inner walls of the left and right side panels of the box, and slide grooves are formed between the two adjacent support strips, so that the edge of the pan can be inserted into the corresponding slide groove to achieve support. When the cooling coil is also installed on the inner walls of the left and right side panels of the box, it will interfere with the slide groove, affecting the placement of the pan. Utility model content:
