Description

Technical Field

[0001] This utility model relates to the field of radiative cooling technology, and in particular to a radiative cooling temperature control effect testing device that can simulate various climates. Background Technology

[0002] With the escalating global warming and energy crisis, the development of efficient cooling technologies has become an urgent need for the international community. Radiation cooling technology, with its unique mechanism of dissipating heat into outer space through infrared radiation, possesses significant advantages in energy conservation, environmental protection, and sustainable operation, showing broad application prospects in areas such as building energy conservation, thermal management of electronic equipment, and cooling of new energy equipment. However, the actual effectiveness of this technology is highly dependent on complex climatic environments. Dynamic changes in environmental parameters such as temperature, humidity, wind speed, and solar irradiance can significantly affect the performance of radiation cooling materials. Therefore, constructing a testing platform capable of simulating multiple climatic conditions and achieving accurate performance evaluation has become a key bottleneck in promoting the engineering application of radiation cooling technology.

[0003] Current radiative cooling performance testing technology faces several technical bottlenecks: First, traditional testing devices generally employ a single environmental parameter control mode, making it difficult to reproduce the multi-parameter coupling effects in real atmospheric environments. For example, some radiative cooling materials exhibit significant performance degradation under high temperature and humidity conditions, while performing excellently under low temperature and low humidity conditions. However, existing devices cannot dynamically switch environmental parameters across climate zones within the same system. Second, insufficient equipment integration leads to low testing efficiency. Most devices use a discrete instrument combination mode, resulting in bloated structures, cumbersome operation procedures, and long calibration cycles. Furthermore, they lack multi-sample parallel testing capabilities, and a single test can only complete the evaluation of a single sample, failing to meet the high-throughput testing requirements of the material formulation screening stage. Third, existing devices cannot accurately capture the characteristics of temperature, humidity, and wind speed, further limiting the research and application of radiative cooling technology. For example, Chinese patent application CN202310804404.5 discloses an all-weather radiative cooling material radiative energy power testing device and its testing method. Its drawback is that it is only suitable for monitoring external environmental parameters and cannot achieve temperature control effect testing and cooling power testing under specific environments. Chinese patent application CN202210950755.2 discloses a device and method for measuring radiative cooling power, but its drawback is that it only has a power testing function and does not consider the intuitive effect of temperature comparison in the application of radiative cooling. Chinese patent application CN202010600538.1 discloses a device and system for measuring radiative cooling power, but it cannot achieve comparative analysis between multiple samples, nor can it perform targeted evaluation tests under actual climatic conditions.

[0004] In summary, there is an urgent need to design a device that can solve problems such as single climate simulation, low sample testing efficiency, and reliance on manual data processing, so as to improve the efficiency and accuracy of radiation cooling material testing.
