半导体制冷制热便携式饭盒设计说明书

北京理工大学珠海学院 2020 届本科生毕业设计半导体制冷制热便携式饭盒设计说明书半导体制冷制热便携式饭盒摘 要半导体制冷制热便携式饭盒（Semiconductor HOT/COLD Food Preserve Box，）是一种能够根据保存的食物所需温度的不同，在一个箱体里同时拥有冷暖两个分区的箱子，并且通过电池供电，满足外卖送餐员的送餐工作的需求。设计过程中使用 CREO 5 软件进行 3D 建模，绘制出三维视图，做出最终的实物成品并测试。相较于市面上使用的绝大部分外卖箱采用的被动保温，本设计采用主动保温，可以更好地维持餐品在运输过程中有着更适宜进食的温度，提高顾客的满意度，也为外卖店铺拓展更远距离的业务提供了条件。关键词：半导体制冷；冷热两用；电池供电； 北京理工大学珠海学院 2020 届本科生毕业设计Design specification of portable lunch box made of semiconductor refrigerationAbstractSemiconductor HOT / COLD Food Preserve Box (Semiconductor HOT / COLD Food Preserve Box,) is a kind of box that can have both cold and warm partitions in a box according to the temperature of the stored food, and is powered by batteries. Demand for food delivery from the food delivery staff. In the design process, CREO 5 software was used for 3D modeling, drawing a three-dimensional view, and making the final physical product. Compared with the passive insulation used in most of the takeout boxes on the market, this design uses active insulation, which can better maintain the 北京理工大学珠海学院 2020 届本科生毕业设计temperature of the food during the transportation process to be more suitable for eating, and also expand the distance for takeaway shops Business provides the conditions.Keywords: Semiconductor refrigeration; cold and hot; battery-powered;目 录1. 前言..............................................................................................................................................1 1.1 本设计的目的、意义及应达到的技术要求............................................
