Description
Technical Field
The invention relates to a hydrogen-nickel storage battery for a space, belonging to the technical field of space batteries.
Background
The hydrogen-nickel storage battery monomer for the space is a cylinder with two hemispherical ends, when the storage battery pack is assembled, the hydrogen-nickel storage battery monomer is combined with the conical heat dissipation sleeve, then the heat dissipation sleeve is fixed on the bottom plate through a fastener, the combination of the hydrogen-nickel storage battery monomer and the conical heat dissipation sleeve adopts a cementing method, namely a certain gap is designed between a shell of the hydrogen-nickel storage battery and the heat dissipation sleeve so as to be filled with heat-conducting silica gel, and the battery monomer is supported and fixed by utilizing the good bonding performance of the heat-conducting silica gel. The silica gel is required to meet the requirement of mechanical and thermal properties, and meanwhile, a silica gel bonding area must have an enough area, because the bonding strength is related to the shearing strength of the silica gel, and is also directly related to the size of the bonding area of the silica gel, if the bonding area of the silica gel is not enough, a storage battery monomer is separated from a heat dissipation sleeve under the mechanical environment conditions of impact, vibration and the like in the process of launching, attitude adjustment or orbital transfer of a spacecraft, and the storage battery pack fails.
Moreover, the heat-conducting silica gel filled between the storage battery monomer and the heat dissipation sleeve also plays a role in transferring the heat of the storage battery. On a spacecraft with a vacuum environment, the most important heat transfer routes are as follows: the heat generated in the storage battery monomer is conducted out from the storage battery shell to the bottom plate through the heat conducting silica gel, the heat conducting silica gel and the heat radiating sleeve, and then the heat is conducted out from the bottom plate through the spacecraft cabin plate. If the heat conduction silica gel between the storage battery monomer and the heat dissipation sleeve is not uniformly or insufficiently filled, the area which is not coated is in a vacuum heat insulation state or a gas state (the heat conductivity coefficient of air is about 0.0251W/m.K), the heat conduction of the part is blocked, the temperature of different parts of the storage battery monomer is uneven, the performance of the storage battery monomer is reduced, meanwhile, the silicon rubber shortage between the storage battery monomer and the heat dissipation sleeve is equivalent to the reduction of the heat transfer area of the storage battery monomer, the heat flow density is increased, the aggravation of unsmooth heat transfer is caused, the heat transfer effect is poor, the temperature among the storage battery monomers is uneven, the performance and the reliability of the battery pack are reduced.
The existing heat-conducting silica gel filling process adopts a method of manually coating natural flow gel, namely, a layer of glue material is manually coated on the surface of a straight cylinder section of a storage battery shell by a scraper, and then the glue material is inserted into a heat dissipation sleeve to be cured.
During manual coating, the thickness of the sizing material on the shell is not uniform, and during the process of inserting the heat dissipation sleeve, because the silicon rubber has viscosity and is difficult to flow under the condition that the gap is very small, most of the silicon rubber is blocked outside the gap, so that the sizing material in the gap is not completely filled, even less than 50%. Therefore, the manual coating process has poor filling effect, low production efficiency and is not suitable for the requirement of batch production.
