ABSTRACT:
A projection apparatus having a temperature controlling system is provided. The projection apparatus comprises at least a heat generating element, while the temperature controlling system comprises a liquid flow system, a heat generating device, and a heat transferring device. The liquid flow system is disposed along the heat generating element. The heat generating device produces heat with a positive value (endothermic) or a negative value (exothermic) in response to an environment dependent on the location of the projection apparatus. The heat transferring device transfers the heat generated by the heat generating device along the liquid flow system. The present invention maintains the operation of the projection apparatus under the desired working temperature and enables a thermal equilibrium of the projection apparatus without being influenced by the over-temperature or under-temperature of the external environment.
