Low-temperature heating radiator

Abstract

The invention relates to a low-temperature heating radiator which comprises one or more sets of plate like heat transportation devices and one or more parallel channel type fin heat exchange structures combined with the plate like heat transportation devices. Each plate like heat transportation device is of a plate like structure formed by extruding metal materials, wherein two or more micro pipes arranged side by side are arranged in the plate like structure, and heat exchange transfer is carried out in the micro pipes through flowing media.

Heat exchange is enhanced by means of the plate like heat transportation devices of the special structures, and the parallel channel type fin heat exchange structures are attached to the plate surfaces of the corresponding plate like heat transportation devices correspondingly, so that natural air convection heat exchange and forced air convection heat exchange can be carried out as needed, the heat exchange efficiency is improved, an effective heating function is achieved, the low-temperature heating radiator has the advantages of being low in temperature, capable of saving energy, low in cost and free of maintenance, and meanwhile precision management and energy saving can be achieved.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation engineering, in particular to a low-temperature heating radiator. Background technique [0002] At present, one type of indoor air heat exchange at the heating end is natural convection with radiation heat exchange, that is, passive heat dissipation methods such as radiators, floor heating, etc., and one type is radiant heating based on high-temperature radiation, such as Yuba, etc. Passive, there is also a fan coil type forced convection heating, which is an active method. At present, both passive and active heaters have advantages and disadvantages, but they are completely independent systems and are not compatible with each other. [0003] The water supply temperature of the current natural convection radiators is relatively high, and the heat dissipation area on the surface of the radiator is generally designed according to the most unfavorable load. Wastes a lot of energy an...

[0005] The invention aims at traditional radiators adopting larger diameter circular tubes with small surface area, resulting in low heat transfer coefficient and traditional plate-type low-heating radiators with high cost and complex process, and it is impossible to adopt forced convection active way to enhance heat exchange and traditional radiator air side heat exchange To adapt to the poor adjustment ability of changing loads, a low-heat radiator is provided, which strengthens heat exchange through a plate-shaped heat transport device with a specific structure and compound parallel channel fin heat exchange structure on its plate surface, with parallel channels enclosed around The finned heat exchange structure has a specific air convection channel, which can perform natural air convection heat exchange according to needs, and further cooperate with forced air convection heat exchange. According to needs, the convection mode can be automatically adjusted and selected to improve heat exchange efficiency and realize effective heating functions. , since the air heat exchange area outside the tube, convective heat transfer and liquid flow heat transfer in the tube have been greatly improved, it can realize heating at low water supply temperature, realize the advantages of energy saving, low cost, and maintenance-free, and can realize Intelligent fine management and energy saving
