Embodiment Construction
[0021] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0022] Such as Figure 1-3 As shown, the pipeline antifreeze protection device of an embodiment of the present invention includes a microchannel heat exchanger 10 and an insulating layer 20 arranged oppositely; the microchannel heat exchanger 10 is arranged on the inner peripheral surface of the pipeline 11 for absorbing the The heat of the inner medium can transfer heat to the pipe wall of the pipe 11 to prevent freezing of the pipe 11;
[0023] The microchannel heat exchanger 10 and the insulation layer 20 are arranged oppositely on the inner and outer sides of the pipeline 11, and enclose the pipe wall of the pipeline 11 therein.
[0024] The micro-channel heat exchanger 10 is ring-shaped and fits closely on the inn...

The invention discloses a pipeline anti-freezing protection device and a pipeline anti-freezing protection device for a liquid energy storage tank. The pipeline anti-freezing protection device comprises a micro-channel heat exchanger used for absorbing medium heat in a pipeline and transmitting the heat to the pipe wall of the pipeline, and a heat preservation layer used for carrying out heat preservation on the pipeline. The micro-channel heat exchanger is arranged on the inner peripheral surface of the pipeline, the heat preservation layer is arranged on the outer peripheral surface of the pipeline, and the micro-channel heat exchanger and the heat preservation layer are oppositely arranged on the inner side and the outer side of the pipeline to wrap and the pipe wall of the pipeline. Heat stored in media in the pipeline is absorbed through the micro-channel heat exchanger, and the characteristic that the micro-channel heat exchanger is used for rapidly transferring heat is utilized, so that heat is transmitted to the pipeline; the problem that the pipeline is frozen or damaged by freezing can be effectively solved, and no extra heat source and auxiliary equipment are needed; and the use method is simple and convenient, and the anti-freezing effect is good.
Description
technical field [0001] The invention relates to the field of antifreeze technology for pipe fittings, in particular to a pipeline antifreeze protection device and a pipeline antifreeze protection device for a liquid energy storage tank. Background technique [0002] Energy storage technology utilizes the difference in peak and valley electricity prices to store cold / heat in the medium during the low-valley electricity price period, and use the stored cold / heat medium to provide cooling / heating for air conditioning during the peak hours of electricity consumption during the day. The energy storage tank has low initial investment, simple system, convenient maintenance, and has broad development space and application prospects. Its social benefits are reflected in the balance of power grid load, reduction of power plant investment, and environmental purification. The use of energy storage tanks is increasing year by year, and the northern cold regions are also developing rapidl...
