Description
Technical field
The utility model relates to heat exchanger, is specifically related to a kind of heat exchanger for flat heat pipe.This heat exchanger for flat heat pipe is specially adapted to the cooling of confined spaces such as outdoor electric power, communication or electrical control rack, and to the energy-conservation ventilation in the place of using air-conditioning.
Background technology
In electric power, communication or industry such as electric, be extensive use of the control rack, in order to prevent that moisture, dust, pernicious gas from entering rack, rack is usually to outer closure, be in operation because of device in the rack self evolution of heat or outdoor solar radiation, temperature can constantly raise in the rack, will certainly influence the operate as normal of device in the rack as untimely heat radiation, therefore in electric power, communication or electrical control rack, need the special heat exchanger of configuration to rack in the air heat radiation.
On the other hand, in the place of using air-conditioning,, no matter be the refrigeration in summer as market, office, hospital, dwelling house etc., still heat winter,, help keeping indoor temperature if close window, but at this moment indoor air can dirtyly gradually lose, and makes us producing tiredness, and unfavorable health.If directly window, open the door or can make room air keep pure and fresh with ventilating fan ventilation, but can cause the loss of cold and heat thereupon.If adopt a kind of heat exchanger that the air and the outdoor ozone of indoor dirty erosion are carried out heat exchange, outdoor like this fresh air is after summer will precooling in the inlet chamber, after winter can preheating in the inlet chamber, thereby reduce the loss of cold (or heat), reach the energy-conservation again effect of ventilation.
In present heat exchanger, the product that can satisfy above two kinds of use occasion requirements on the performance has plate-fin heat exchanger, cross-flow plate type heat exchanger and heat exchange of heat pipe.The plate-fin heat exchanger complex manufacturing technology, consumptive material is many, and weight is heavy again, and the cost of manufacture height causes the price height, and it is infeasible substantially to use it for above-mentioned two kinds of occasions.And the structure of cross-flow plate type heat exchanger can be announced on April 1st, 2009 disclosed referring to Chinese patent, notification number is the utility model patent of CN201215454, it has light weight, volume is little, production technology is simple, the advantage that cost of manufacture is low, be applicable to above-mentioned two kinds of use occasions, but it has the loss of thermograde, its heat exchange efficiency is still limited, and its needs to have under the condition of a fixed difference difference (Δ t is bigger) the heat exchange both sides could operate as normal, as summer outdoor temperature up to more than 45 ℃, and temperature is at 50 ℃ in the control rack, and this moment, the cross-flow plate type heat exchanger was with regard to cisco unity malfunction.And the heat exchange of heat pipe structure as shown in Figure 1, by tens or tens cross sections is that circular heat pipe 21, polylith heat exchanger fin 22 and central dividing plate 23 formed, heat exchanger fin 22 and central dividing plate 23 are layer by layer at a distance of arranging, central dividing plate 23 is positioned at the centre position, 22 of each heat exchanger fins form air channel 24, tens or tens heat pipe 21 arrayed and vertically run through heat exchanger fin 22 and central dividing plate 23,22 modes by expand tube or welding of heat pipe 21 and heat exchanger fin are fixed, and guarantee transmission of heat by contact between the two.During use, with the thermal insulation board be boundary's one side as condensation end, opposite side is as evaporation ends.Above-mentioned heat exchange of heat pipe is applied to dispel the heat on the electric equipments such as electric welding machine at present, and because of it adopts hot pipe technique, its heat exchange efficiency is than cross-flow plate type heat exchanger height, and still, it still has the following disadvantages:
1, reach tens independent heat pipe because of adopting, every heat pipe individual packages, its cost of manufacture height, and the package quality of numerous heat pipes also is difficult for protecting levying;
2, with the assembling of heat pipe and heat exchanger fin the time, if with the expand tube mode big heat exchange efficiency that influences of thermal resistance between the two then, if then limited the selection of worker quality liquid in scolder and the heat pipe with welding manner, it is improper to select, and the high temperature during welding can cause the explosion of heat pipe;
3, because of the heat pipe of the cross section circle that adopts arrayed, the air channel is longer, and heat pipe to take the sectional area in air channel more, windage is increased, for this gas-distributing fan power also need strengthen, energy consumption increases.
