This creation, which ties up to, provides a kind of pad with changes in temperature effect,The pad can choose at hot day to feel cold,And can choose fever in cold day,Have the function of to adjust temperature,It includes there is upper heat-conducting plate,For a flat plate body,Heat-conducting plate has a upper surface and a lower surface on this； Lower heat-conducting plate,For a flat plate body,The lower heat-conducting plate has a upper surface and a lower surface； Thermal insulation board,For a flat plate body,The thermal insulation board has a upper surface and a lower surface,And the thermal insulation board offers hole； Cooling wafer,The cooling wafer system sets in the what hole,The cooling wafer has a upper surface and a lower surface； The thermal insulation board system is laminated on what between heat-conducting plate and lower heat-conducting plate,And the upper surface of the cooling wafer attaches the lower surface of heat-conducting plate on what,And the lower surface of cooling wafer attaches the upper surface of heat-conducting plate under what. Polarity by control input cooling wafer DC power supply carrys out the effect of heating up or cooling down as pad using face.本創作係在提供一種具有冷暖效果之墊體，該墊體在熱天時可以選擇發冷，而在冷天時可以選擇發熱，具有調節溫度之功能，其包含有上導熱板，為一扁平之板體，該上導熱板具有一上表面及一下表面；下導熱板，為一扁平之板體，該下導熱板具有一上表面及一下表面；隔熱板，為一扁平之板體，該隔熱板具有一上表面及一下表面，且該隔熱板開設有孔；致冷晶片，該致冷晶片係設於該孔中，該致冷晶片具有一上表面及一下表面；該隔熱板係層疊於上導熱板及下導熱板間，且該致冷晶片之上表面貼附於上導熱板之下表面，而致冷晶片之下表面貼附於下導熱板之上表面。藉由控制輸入致冷晶片直流電源之極性來做為墊體使用面升溫或降溫之功效。
