• intros：{"brand_intro":"雪科（Xueke）成立于2005年，中国浙江民营制冷设备企业，以\"高性价比、快速交付\"著称。创始人李雪峰原是空调维修工，后转型研发实验室冷水机。品牌采用\"互联网直销\"模式，砍掉中间商，价格仅为同类进口1/10。虽然技术积累不如一线品牌，但凭借灵活定制和7天无理由退换，在中小企业和个人实验室中拥有大量粉丝。","product_intro":"XK-2000是一款入门级实验室冷水机，主打\"够用、便宜\"。核心卖点：2000W大制冷量、不锈钢水泵、数显温控。相比新芝DC系列，制冷量更大但精度更低（±1℃）。适用场景包括小型反应釜、UV固化机、激光打标机冷却。用户评价\"便宜大碗\"，但故障率略高。适合预算极低或非关键冷却需求。","key_specs":{"制冷量":"2000W（@20℃）","控温精度":"±1℃","水箱容积":"15L，不锈钢材质","压缩机类型":"涡旋式，低功耗","适用设备功率":"≤1000W"}}
