The utility model discloses a reciprocating piston compressor split type air cylinder seat which comprises a lower base, a positioning groove is formed in the top of the lower base, an air cylinder head is connected in the positioning groove in an abutting mode, the air cylinder head is installed on the lower base through a fastener, a shaft hole is formed in the lower base, and a cylinder hole is formed in the air cylinder head. According to the split type air cylinder seat, due to the fact that the bottom end part of the back plate abuts against the interior of the first positioning groove, the lower base can be used for providing more support for the air cylinder head and the air cylinder, and the requirement for the connection strength between a fastener and the lower base is lowered; and meanwhile, the first positioning groove and the second positioning groove are used for positioning when the back plate and the piston cylinder are installed, so that the installation position of the air cylinder head is conveniently determined, and the air cylinder head is prevented from moving at will in the installation process.

This application provides an on-board cooling device and a cooling vehicle. The on-board cooling device includes: a housing with multiple vents; and multiple heat dissipation systems, each including a fan and a cooling system. The fans of the multiple heat dissipation systems are respectively disposed at the multiple vents to drive gas in the housing to flow out through the multiple vents. The cooling systems of the multiple heat dissipation systems are all disposed in the housing and connected in parallel to provide cooling liquid to the heat-generating equipment to absorb heat from the heat-generating equipment, and the absorbed heat is carried away by the gas driven by the fans, thereby cooling the heat-generating equipment. In this way, the cooling capacity of the on-board cooling device and the cooling vehicle can be enhanced, better meeting cooling needs.

This invention provides a two-dimensional triangular lattice rare-earth-based titanate polycrystalline material, its preparation method, and its applications. The chemical formula of the rare-earth-based titanate polycrystalline material is Ba6M2Ti4O. 17 The space group is P63 / mmc, where M is one or more of Nd, Gd, and Yb. The novel two-dimensional triangular lattice rare-earth-based titanate polycrystalline material provided by this invention has a compact structure, a simple preparation process, and its frustrated structure of localized electron spins significantly reduces the minimum cooling temperature to the tens of millikons. Furthermore, it exhibits high magnetic ion density and large cooling capacity, making it an excellent magnetic refrigerant.
