Description
Technical field
The utility model relates to energy-conservation Refrigeration Technique, particularly a kind of natural refrigerated separation formula heat exchange of heat pipe.
Background technology
Heat dissipation equipment is concentrated in equipment room, the machine room, and heat dissipation capacity is big, adopts common air-conditioning to move throughout the year, and power consumption is big, is unfavorable for energy-saving and emission-reduction.Make full use of outdoor cold source at transition season, can effectively reduce the operation of air conditioner power consumption, but existing introduce brand-new wind and carry out a lot of at home regions of temperature reduction way and is not suitable for, a large amount of outdoor dust and humid air can be brought into indoorly, influence the indoor equipment safe operation; The another kind of form of wind-wind heat exchanger that adopts can avoid that outdoor dust and humid air introducing is indoor, but need offer bigger ventilation hole in equipment room, machine room building enclosure, not only destroys wall stability, also brings the stolen potential safety hazard of indoor equipment.
Be 200910072346.1 as application number at present, name is called the patent application of " split type compressor-free heat exchange air conditioner ", basically the problems referred to above have been solved, its disclosed air-conditioner, comprise indoor set, off-premises station, be connected with down-comer by tedge between indoor set and the off-premises station, indoor set is positioned at the off-premises station below, indoor set is made up of heat exchange unit and heat exchange blower fan, off-premises station is made up of heat-sink unit and cooling fan, and heat-sink unit and heat exchange unit are formed by many heat exchanger tubes, two collectors and Duo Gen tube connector.The gravity that utilizes the difference in height of refrigerant pressure reduction that indoor/outdoor temperature-difference causes and indoor and outdoor heat exchanger tube to form circulates refrigerant between the heat exchanger tube of indoor and outdoor, thereby reached the purpose of atural beat exchange, it is many to have solved the common air-conditioning power consumption, increase the defective of greenhouse gas emission, but still there are some problems in the air-conditioner of this patent application: it is in order to improve rate of heat exchange and efficient, the quantity that need as often as possible increase heat-exchange tube is to increase heat exchange surface area, this can increase the air-conditioning volume on the one hand, make air-conditioning cost and price have to improve on the other hand, increased use cost.
The utility model content
Problem according to the existence of above-mentioned field, provide exploitation a kind of natural refrigerated separation formula heat exchange of heat pipe that utilizes the separate heat pipe technology, the equipment room, the machine room that can be used for concentrating to heat dissipation equipment dispel the heat, and its hot utensil of heat pipe pipe than equal volume has higher heat exchange efficiency.
A kind of natural refrigerated separation formula heat exchange of heat pipe, constitute by the off-premises station of tedge and down-comer connection and the refrigerant of indoor set and the interior filling of pipe, indoor set comprises indoor heat exchange unit, off-premises station comprises the outdoor heat exchange unit, described indoor heat exchange unit and outdoor heat exchange unit all comprise heat exchanger tube, form the closed conduit that described refrigerant can circulate therein between described outdoor heat-sink unit, tedge, down-comer and the indoor heat exchange unit, it is characterized in that described vertical heat exchanger tube all twines the aciculiform fin outward.
Described refrigerant is the ammonia heat-exchange working medium.
There is airtight valve described down-comer and tedge and outdoor heat-sink unit or indoor heat exchange unit junction.
The heat exchanger tube of indoor heat exchanger of the present utility model and outdoor heat exchanger all twines the aciculiform fin outward with enhanced heat exchange, because big many of the external surface area of the more traditional flat fin of aciculiform fin, in same heat exchanger volume, can possess bigger heat exchange area, therefore can strengthen the heat exchange effect, reduce the heat transfer temperature difference of heat pipe, make separate heat pipe have higher heat exchange Energy Efficiency Ratio.Thereby can realize low cost, high efficiency heat exchange effect.
The utility model preferably adopts the ammonia heat-exchange working medium as refrigerant, because the operating temperature range of ammonia is-200 ℃～120 ℃, and has very big potential heat value, the heat dissipation environment temperature of equipment and heat dissipation element is generally-30 ℃～80 ℃, therefore is well suited for being used for separate heat pipe as giving equipment room, machine room heat radiation.Ammonia working medium is in a liquid state in indoor heat exchanger.The heat that indoor equipment or other heat dissipation element distributed is by ammonia working medium heat exchange in the vertical heat exchange tube and tube, ammonia working medium becomes gaseous state by the liquid state evaporation, the pushed at high pressure effect that gaseous ammonia working medium produces in evaporation, enter off-premises station along tedge, under outdoor Cryogenic air cooling effect, in the outdoor heat exchanger efficient heat-exchanging pipe, condense, condensation water is under the gravity effect, be back to indoor set along down-comer, finish the circulation cooling.
In a kind of preferred embodiment of the present utility model, described down-comer or tedge and outdoor heat-sink unit and indoor heat exchange unit junction are provided with airtight valve, are used for the ammonia working medium that the utility model separate type heat pipe exchanger is filled in heat exchange unit and the outdoor heat-sink unit in the transportation confined chamber; Be pre-charged with ammonia working medium and be to make indoor heat exchanger and outdoor heat exchanger to be in barotropic state all the time, avoid air to enter heat exchanger and cause corrosion with the airtight benefit of valve; Not be used in the on-the-spot ammonia working medium of filling of equipment room, machine room, reduce the site operation amount, and avoid on-the-spot loading can't guarantee the hidden danger of quality that brings when accurate.
Among all embodiment of the present utility model, can preferably adopt a control system and equipment room, the original air-conditioning of machine room to link, when judging that automatically outdoor cold source is sufficient, control system closes original air-conditioning, start nature refrigerated separation formula heat exchange of heat pipe operation cooling, section is by between original operation of air conditioner cooling support equipment, equipment operates in proper temperature environment in the machine room At All Other Times.
In sum, heat exchange of heat pipe of the present utility model has does not increase greenhouse gas emission, low-carbon energy-saving, and economical and practical advantage can be used as normal domestic air-conditioning, office's air regulator, and operating office is with air-conditioning etc., but is not limited thereto.
