Abstract
The utility model relates to a cooling and warming seat cushion which is provided with a metal panel. A box under the seat cushion is split into a cold zone and a hot zone by a heat-insulating board. A semiconductor cooling element is arranged on the heat-insulating board, cooling down the metal panel, and heating the metal panel while the power supply is inversed. Only cooling down or heating the local part of a chair surface, the seat cushion has low power consumption and energy saving and is particularly suitable for a driving cab seat, and can effectively improve working conditions of the driver just by locally cooling down or heating in summer or winter.
Description
The utility model relates to seat cushions, particularly a kind of changes in temperature seat cushion of conductor refrigeration.
In summer, car steering is indoor, and the chair cushion of driver's buttocks and legs minister's time with softness contacts, even the upper body well-ventilated still feels lower part of the body muggy and oppressive.In the seat cushion that is to use rattan, bamboo pad or enclosed liquid.But chair cushion also can very fast absorption heat and the basic isothermal of human body, loses refrigerant effect, and terribly cold in the driver's cabin winter, warm seat cushion also can make the people drive away nip in the air.
The purpose of the utility model is to provide a kind of changes in temperature seat cushion, to improve the condition of work of driver driving under the non-air conditioner surroundings.
Described changes in temperature seat cushion has casing and metal seat, and the cold junction of semiconductor cooling element is connected with heat-conducting plate, and heat-conducting plate is adjacent to and is fixed on the metal seat, and the hot junction of semiconductor cooling element connects fin, and lower box has exhaust window and ventilating fan is housed.
The utility model adopts semiconductor cooling element as cold (heat) source, and it is low in energy consumption, can use automobile storage battery to be power supply, and noiselessness.The cold junction of semiconductor cooling element directly contacts with the metallic chair panel by heat-conducting plate, does not need the central fluid medium to conduct heat the heat transfer efficiency height.Because local the feeling nice and cool of human body buttocks and legs just can make general sensation refrigerant, thereby only local refrigeration just can improve driver's condition of work effectively to seat cushion, and is energy-conservation.In addition, change the sense of current of semiconductor cooling element, Refrigeration cushion just becomes the heating pad, and described seat cushion promptly is suitable for also being suitable for summer using winter.
Fig. 1, the cutaway view of described seat cushion;
Fig. 2 adopts the automotive seat of described seat cushion.
Horizontal thermal insulation board 8 will be divided into cold-zone and hot-zone in the casing 5 in the casing, semiconductor cooling element 3 is in the installing hole place of thermal insulation board 8, the heat-conducting plate 2 that its cold junction connects is in the cold-zone, the another side of heat-conducting plate 2 is adjacent to metal seat 1, and the fin 6 that the hot junction of semiconductor cooling element 3 connects is in the hot-zone.Casing 5 bottoms have exhausting window 4, and ventilating fan 7 is housed, and it stirs the air heat radiation of hot-zone, and elastic mechanism 9 is installed in described seat cushion bottom, and backrest is installed at the rear portion, constitutes automotive seat shown in Figure 2.The utility model also can be made into the seat of conventional chair, and the room that is suitable for non-air conditioner surroundings uses.
Claims (2)
1, a kind of changes in temperature seat cushion, it is characterized in that having casing 5 and metal seat 1, the cold junction of semiconductor cooling element 3 is connected with heat-conducting plate 2, heat-conducting plate 2 is adjacent to and is fixed on the metal seat 1, the hot junction of semiconductor cooling element 3 connects fin 6, and casing 5 bottoms have exhaust window 4 and ventilating fan 7 is housed.
2, by the described changes in temperature seat cushion of claim 1, it is characterized in that horizontal thermal insulation board 8 is arranged in the casing 5, casing 5 is divided into cold-zone and hot-zone, heat-conducting plate 2 is in the cold-zone, and fin 6 is in the hot-zone.
