The new composite phase changing heat accumulating heating technology includes adding heat accumulating pipe and heat accumulating capsule into traditional electric heating set and filling heat medium in the gaps. The heat accumulating medium takes phase change while being heated and cooled to form one latent heat accumulating process. The heat medium acts as the fluid medium for heat transfer between the heated surface and the heat accumulating medium to strengthen the heat transfer inside the heat accumulating medium on one hand, and takes temperature change as one sensible heat process accompanying the heat accumulating and releasing on the other hand. The technology of the present invention can strengthen the heat transfer process inside heat accumulating medium, raise heat accumulating capacity and decrease size of heat accumulating apparatus.

The invention discloses a heat-insulating fluffy down quilt and a preparation process thereof. The heat-insulating fluffy down quilt comprises a down quilt cover and an inner core, wherein the inner core is coated with the down quilt cover; the inner core is filled with bamboo charcoal fibers and pretreated wool and down feather. The heat-insulating fluffy down quilt is prepared by the following steps: 1) pretreatment of down feather: sterilizing-stem removal of raw materials-removal of sand dust-refining-primary cleaning-washing-dehydration-drying; 2) pretreatment of wool; 3) preparation of the down quilt: uniformly mixing the bamboo charcoal fibers and the pretreated wool and down feather, and then filling an inner core sleeve of the down quilt with the mixture. According to the heat-insulating fluffy down quilt disclosed by the invention, the down feather, wool and bamboo charcoal fibers are taken as the raw materials, the down feather is screened twice through a down feather screening machine to select high-quality large down feather, and then mixed with the wool and bamboo charcoal fibers for filling, and the mixture is treated with an anti-bacterial agent, so that the prepared down quilt has a good anti-bacterial effect, heat-insulating performance and fluffiness.

The invention discloses a trough type light-condensing solar thermoelectric generator which comprises a trough type light-condensing device and a receiving tube. The receiving tube is opposite to the inner cambered surface of the trough type light-condensing device and comprises an inner wall and an outer wall, the inner wall defines a hollow cavity penetrating two ends of the receiving tube, the cavity between the inner wall and the outer wall is divided into multiple sealed filling cavities through metal heat-conducting units, each sealed filling cavity is full of heat-conducting oil, thermoelectric power generation pieces are installed on the side close to the hollow cavity, in the inner wall, in the linear direction, and covers the inner wall partially or wholly, and water-cooling pieces are installed on the cooling face of the thermoelectric power generation pieces. The interlayer cavity of the receiving tube is filled with heat-conducting oil, the heat-conducting oil has certain heat storage effect, and even if sunlight is interrupted, power generation can be also sustained for a period of time. The fluctuation changing with sunlight during electric energy output is reduced, the cavity between the inner wall and the outer wall is discontinuous, the inner wall and the outer wall are still partially connected through the metal heat-conducting units made of aluminum alloy and the like, and the problem that external heat cannot be transferred to the inner wall due to poor heat-conducting performance of the heat-conducting oil is avoided.

The invention discloses a down fabric, which is characterized in that it comprises an outer layer of the fabric, a down layer and an inner layer from top to bottom; Bonded together by an adhesive layer; wherein, the outer layer of the fabric is made of the following raw materials in parts by weight: polypyrazolo[1,5‑A]‑1,3,5‑triazine‑2,4 (1H,3H)-diketone 3-(tert-butyldimethylsiloxy) glutarate 50-70 parts, polydicarboxyethyl germanium trioxide polytetrahydrofuran glycol ester 20-30 parts, oxidation Graphene 10‑15 parts. The down fabric disclosed by the invention has excellent air permeability and the effect of preventing the down from drilling out, and has good water resistance, cold resistance, weather resistance and flame retardancy, and has a good hand feeling. In addition, it also has the health care function of promoting blood circulation .
