Description

A kind of reactor heat abstractor

Technical field

The utility model relates to a kind of radiating element of power equipment, refers in particular to a kind of large power reactor heat abstractor, and international Patent classificating number is B61F05/02, is mainly used in the heat radiation of various large power reactors or transformer.

Background technology

Because various reactors all can generate heat when work, so generally all will cool off to reactor, the medium of cooling mainly is You Heshui at present, reactor is divided into open-core type, iron core formula, dry type, oil immersed type etc. by structure and coolant, for example dry-type air-core reactor, reactor with T-shaped core, oil immersion iron core reactor, oil-immersed hollow reactor, clipping dry-type air-core reactor, wrapped formula dry-type air-core reactor, cement reactor etc.High-power iron core formula reactor is a kind of electrical auxiliary service that is widely used in various High power Traction electric power systems, because the big caloric value of power is also just big, so generally adopt external water-filled radiator to dispel the heat for this class reactor; This water-cooling is that a water cooling plant is arranged in the reactor, by circulation pipe the hot water in the reactor derives again, is input in the reactor after entering the cooling water tank cooling again, and the water by continuous circulation cools off reactor, reaches the purpose of heat radiation.

But this class iron core formula water-cooling reactor all is to adopt the lateral location at reactor winding that heating panel is set at present, and the cooling water pipe of some circulations is set and the heating panel of reactor side couples together at the peripheral position of reactor winding and iron core, taking (sending out) heat of reactor out of radiator by recirculated cooling water cools off, though such type of cooling has certain radiating effect, but exist bulkyly, structure comparatively complexity waits some problems; Especially because the cooling water of circulation must carry out heat exchange cooling by an external cooling water tank, so a recirculated water cooling station must be set around reactor again, make whole (reactor) electrical system volume increase, and become more complicated, and there is the hidden danger of leaking (also very worrying at work to leak) in water circuit system, the decreasing insulating that causes iron core is therefore necessaryly improved this.

The utility model content

This patent utility model problem to be solved is: at the deficiency of existing high-power iron core formula water-cooling reactor radiator structure, not changing under the existing integrally-built condition of high-power iron core formula reactor, the better high-power iron core formula of a kind of heat dispersion reactor radiator structure is proposed.

The purpose of this utility model is achieved through the following technical solutions: a kind of high-power iron core formula reactor heat abstractor, comprise heat pipe and heating panel, the lower part of heat pipe is inserted in core of reactor or the reactor winding, the top of heat pipe is direct and heating panel links together, and heating panel is positioned on the end face of core of reactor; In order to guarantee that heat pipe can effectively be fitted on iron core or the coil, heat pipe is whole to be segmentation unequal section structure, and wherein inserting iron core or coiler part is square structure, and heat pipe and heating panel contact portion are circular configuration.

The utility model utilizes heat pipe to come reactor is dispelled the heat, and dispel the heat by directly fin being set at the reactor end face, have simple in structure, easy to make, the cooling water leakage problem can not appear, especially adopt the heat pipe of straight pipe type can be arranged on any part of core of reactor or coil as required arbitrarily, each root heat pipe all is an independent radiator, and therefore a heat pipe failure can not occur just causes the problem of entire heat dissipation thrashing; And heat pipe can be made the flat-shaped structure of quadrangular section, so that heat pipe can be close on the device surface that needs heat radiation, can effectively improve radiating efficiency.The utility model reactor is compared with traditional reactor under high-power condition, the utlity model has following advantage:

1) the heat pipe density of heat flow rate is big, has a narrow range of temperature; The capacity of heat transmission of its unit are is 3～5 times of silver, so product with compact structure, and volume is little, manufacturability is strong, stable performance; Under equal power situation, reduce weight 1/4th;

2) every heat pipe dispels the heat separately, and power (self-loopa of internal work medium) need be provided during work, and energy-conserving and environment-protective have improved the fault redundance of reactor cooling system;

3) adopt the straight tube heat pipe, cost of manufacture descends, and reduces cost 1/3rd.
