Embodiment Construction
[0019] Compared with traditional organic phase change materials such as paraffin, the thermal conductivity of low-temperature alloys has been improved by two numbers. Therefore, using low-temperature alloys as energy storage materials can store a large amount of heat during the solid-liquid phase transition process, and can effectively resist thermal shock. And maintain the temperature of the cooling target constant. Low temperature alloys also have good electrical conductivity. In addition, as a heat transfer device with good thermal conductivity, the heat pipe has good isothermal properties.
[0020] Such as Figure 1-3 As shown, the energy storage composite temperature control system based on low-temperature alloys includes heat pipe 1, energy storage unit 2, diversion tube 3, and temperature-equalizing heat sink 4; energy storage unit 2 is made of metal, generally light-weight Metal, the inner cavity contains a low-temperature alloy, a plurality of energy storage units 2...

Abstract
The invention discloses a combined energy storage temperature control system based on low-temperature alloy. The system comprises a heat pipe, an energy storage unit, a guide pipe and a temperature equalization cooling fin, wherein the energy storage unit is made of metal materials and communicated with the guide pipe, and low-temperature alloy is arranged in an inner cavity of the energy storage unit; the condensation section of the heat pipe is connected with the energy storage unit, the evaporation section of the heat pipe is connected with the temperature equalization cooling fin, and the temperature equalization cooling fin is connected with a target to be cooled. The system further comprises a fan, wherein the fan is used for cooling the heat pipe and the energy storage unit according to needs, start or stop of the fan is controlled according to the dilatometric change of the size of the low-temperature alloy in the guide pipe, and the rotation frequency of the fan is controlled according to the change of the temperature of the interior of the energy storage unit. By means of the combined cooling method with the good temperature equalization performance of the heat pipe and the energy storage characteristic of the low-temperature alloy combined, the capacity of intermittent working equipment for resisting instantaneous high-temperature heat shock can be effectively improved; by controlling start or stop of the fan according to the change of the size of the low-temperature alloy and controlling the rotation frequency of the fan according to the change of the temperature of the interior of the energy storage unit, energy consumption is lowered.
Description
technical field [0001] The invention relates to a temperature control system, in particular to an energy storage type temperature control system and a method thereof for intermittent work and transient overload applications of high-power heating equipment. Background technique [0002] Brakes in equipment such as elevators and electric vehicles typically operate in an intermittent fashion. This kind of equipment will generate a lot of heat instantaneously when it is working, but it will not generate heat when it is not working. If this part of heat cannot be dissipated to the environment immediately, it will easily cause safety problems of related equipment. In the prior art, a fan for external power supply is usually used to control the temperature of such devices. However, considering the working characteristics of such equipment, it is not economical to simply use fans for temperature control. Contents of the invention [0003] The purpose of the present invention is...
