Technical Field
The invention relates to the technical field of heat exchange of heat pipes, in particular to a heat pipe cold radiation system.
Background
In building energy consumption, the air conditioner energy consumption ratio can reach 30-40%, and with the promotion of low carbon, it becomes increasingly important to further reduce the air conditioner energy consumption. A conventional air conditioner generally includes a cooling system, which provides a cooling source at a temperature lower than an ambient temperature by a cooling means, and exchanges heat between indoor heat and the cooling source, thereby transferring the heat to an external environment. Since refrigeration requires energy consumption, there is a limit to system energy efficiency, typical household air conditioning systems typically have an energy efficiency ratio of around 3.2, and good systems may be slightly higher, but also have their limits.
The operation of the air conditioning system is related to the indoor temperature setting, for example, at 26 ℃, and the air conditioner enters the cooling operation only if the temperature is higher than the indoor temperature, but the operation is not directly related to the outdoor ambient temperature. In actual use, even in summer, the indoor temperature is higher than that of the outdoor temperature for many times. If the outside is just raining too much, the user can feel cool obviously if the user walks out of the room. Or at night, the indoor temperature is often higher than outdoors. In this time, the compressor is still started during the operation of the air conditioner, and large energy consumption exists. If the method of low energy consumption can be adopted, the heat is conducted to the natural environment by utilizing the temperature difference between the indoor and the outdoor, and the energy consumption of indoor temperature reduction can be obviously reduced.
