The invention relates to a driver casing (10). The driver casing (10) is characterized by comprising a first part (1) and a second part (2); the first part (1) is made of electrical insulating material, and the second part (2) is made of conducting material; and the first part (1) and the second part (2) are formed integrally, and the second part (2) extends out of the first part (1) and serves as the electrical connecting part of the driver casing (10). The invention also relates to a luminous device and a lamp. According to the luminous device and the lamp disclosed by the invention, the manufacturing technique is simple, the cost is low, and the heat dissipation capability is remarkably improved.

The invention provides a thermal bridge blocking structure for an aircraft and a preparation method thereof. The thermal bridge blocking structure is located between the high temperature structure and the cold load bearing structure of the aircraft. The thermal bridge blocking structure includes a plurality of heat insulation units, A plurality of heat insulation units are stacked along the direction from the high temperature structure to the cold bearing structure, any heat insulation unit includes a first heat insulation part and a plurality of second heat insulation parts, and a plurality of second heat insulation parts are arranged at intervals on the first The heat insulation parts are distributed along one end face of the stacking direction and along the circumferential direction of the end face, and the projections of multiple second heat insulation parts of any two adjacent heat insulation units on the stacking direction are staggered to extend the high temperature structure and the cold load-bearing structure heat conduction path between. Applying the technical solution of the present invention can solve the technical problem in the prior art that the thermal bridge blocking structure has a poor heat insulation effect in a narrow space and thus cannot meet the heat insulation requirements of high-speed aircraft.

The invention provides a liquefied natural gas cylinder for vehicle and a heavy-duty truck using the liquefied natural gas cylinder for vehicle. A cryopump is connected to a hydraulic control system, a split type inside sleeve comprises a flange, a thin walled tube and a pedestal, and a thermal insulation layer is provided on the outer wall of the thin walled tube as well as between the flange and the pedestal; an overlay welding is carried out for an outside sleeve and the inside sleeve after positioning through a corresponding through hole and a corresponding tapped hole, grooves are respectively formed at bottom parts of the inside sleeve and the outside sleeve, an inverted V-shaped part is combined after connection, and a welding is carried out; a valve seat in a front end supporting device is provided with multifunctional holes, a liquid inlet tube, a liquid outlet tube, a blow-down tube, a liquidometer tube or a safety valve tube are installed in the holes, an over-filling preventing head and an over-filling preventing cylindrical shell are equipped, and the bottom of the over-filling preventing head is provided with a small hole; a rear end supporting device is provided with a small hole on a supporting head, so that the internal space of the supporting head is communicated with the space of the cylinder; a rear end supporting shaft sleeve is made of epoxy glass fiber reinforced plastic; front and back heads of an inner container are provided with molecular sieves; a head of a housing is provided with palladium oxide. The cryopump can be stably installed on the liquefied natural gas cylinder, and heat leakage is effectively reduced.

The invention provides a vacuum thermal insulating plate and a refrigerator. The vacuum thermal insulating plate comprises a core material and a blocking membrane bag. A groove is formed in the side face of the core material. The core material is sealed in the blocking membrane bag. The blocking membrane bag is attached to the outer surface of the core material. The blocking membrane bag is attached to the inner wall face of the groove. By forming the groove in the side face of the vacuum thermal insulating plate, on one hand, the heat conduction route of the blocking membrane bag is lengthened, the heat conduction heat resistance of the blocking membrane bag is increased, and therefore the heat bridge effect in the vacuum thermal insulating plate is reduced, and the thermal insulating effect of the vacuum thermal insulating plate is improved; on the other hand, the contact area between the side face of the vacuum thermal insulating plate and a foamed layer is enlarged, the side face of the vacuum thermal insulating plate and the foamed layer are clamped, the adhesive force between the side face of the vacuum thermal insulating plate and the foamed layer is increased, the foamed layer and the vacuum thermal insulating plate are more firmly combined, and the disengagement phenomenon between the vacuum thermal insulating plate and the foamed layer is effectively avoided.
