The invention relates to an ultraviolet nonlinear crystal temperature control furnace and a temperature control method and an assembly method thereof, the ultraviolet nonlinear crystal temperature control furnace comprises a furnace core assembly, a temperature control assembly and a gas guide assembly, and the ultraviolet nonlinear crystal temperature control furnace adopts flowing high-temperature gas to carry out temperature control in a mode of wrapping and purging an ultraviolet nonlinear crystal. According to the temperature control furnace for the ultraviolet nonlinear crystal, the ultraviolet nonlinear crystal can be uniformly heated, the temperature gradient problem can be solved, the heating and cooling speed is high, meanwhile, flowing high-temperature gas can play a role in protecting the ultraviolet nonlinear crystal, and the temperature control furnace for the ultraviolet nonlinear crystal adopts the annular cavity and the annular gas guide port to circulate gas, so that the temperature control
