Embodiment, the every other embodiment obtained under the premise of creative work is not made by those skilled in the art, belongs to
The scope of this utility model protection.
Embodiment 1
Embodiment square frame shown in Fig. 1 represents rack, is the pyrotoxins such as server or memorizer, now rack is entered in rack
Row radiating.
The embodiment of the present invention provides the purpose of this device, be exactly should not in the case of compressor, by vaporizer in
Gas (being now that pond is evaporated) after coolant heat absorption generation liquid phase conversion takes heat to outdoor and is condensed into liquid through condenser
Vaporization chamber is flow back into automatically, this withdrawing fluid is evaporated by film and combines pond evaporation, is so moved in circles, until it reaches evaporation is cold
Solidifying dynamic equilibrium.
As shown in figure 1, during to cooling machine cabinet, refrigerant evaporator is placed in the rack passage of heat and closes the passage of heat, coolant steams
Chamber 3 (is configured to cavity top as gas collection altogether with vapour point liquid is integrated by the evaporation tube 11 of the hydrophilic aluminium foil fin with shutter to send out device
Room, bottom are liquid collecting room) and liquid collecting room 1 constitute.Refrigerant medium liquid accumulation is in collection vapour point liquid 3 bottom liquid collecting room of chamber, steaming altogether
Send out the bottom of pipe 2, in liquid collecting room 1.When closed gas space temperature is raised, the hydrophilic aluminium foil wing with shutter of evaporation tube overcoat
Piece efficient absorption heat, causes the refrigerant medium rapid vaporization in collection vapour point liquid common chamber 3,11 bottom of evaporation tube and liquid collecting room 1
Pool evaporation is carried out, working medium vaporization rises, from the top that 11 upper end open of evaporation tube is pooled to the common chamber 3 of collection vapour point liquid, then entered
Enter the gas increase in pipeline 42 of this device, then the condenser upper header to condenser 5, then liquefied by condenser, liquefaction cold
Matchmaker's working medium under gravity, by 43 flow down of back liquid pipeline, enters back into the bottom of collection vapour point liquid chamber 3 altogether, then by arranging
Hole for back flow on evaporation tube 11 enters evaporation tube, from top to bottom shower evaporation tube inner pipe wall, forms film evaporation.
The refrigerant medium of circulation is to collect vapour point liquid the bottom coolant of chamber 3, evaporation 11 bottom of sleeve pipe and liquid collecting altogether for the first time
Coolant in room 1 does pool evaporation, and the refrigerant medium of evaporation is back to evaporation tube again carries out film evaporation, at the same collection vapour point liquid altogether
The bottom coolant of chamber 3, the coolant of 11 bottom of liquid collecting room 1 and evaporation tube continue pool evaporation.So, the evaporation of second circulation
Measure the evaporation of capacity of returns film plus the pond evaporation capacity sum of second circulation for first time circulation, its evaporation capacity than first time circulation
Greatly；Such circulation, evaporates collective effect until evaporation and the dynamic equilibrium of condensation by film evaporation and pond.
In such scheme, evaporation tube epimere puts in more than 26mm in the common within the chamber of collection vapour point liquid, and evaporation tube is multiple, institute
There is evaporation tube upper end in same level height, putting on the evaporation tube for collecting the common chamber of vapour point liquid, dividing liquid chamber altogether near collection vapour
1-1.5mm liquid hole for back flow is symmetrically opened at the about 8mm of bottom, and liquid hole for back flow is in same level height, on evaporation tube
Liquid hole for back flow position more than 7mm higher than the liquid outlet position of liquid back pipe.
Experimental data
Refrigeration pair has been done to advanced means of the embodiment of the present invention invention device with the different structure of existing same principle
Than test, under same environment, same operating mode, the embodiment of the present invention collects outlet in equipment cabinet server or memorizer fan hot blast
Passage upper end, middle part upper end, middle part lower end, bottom end, do temperature detection, and it is as follows which contrasts observed temperature：
Its measured result shows that embodiment of the present invention device is made in same environment with current most efficient on the market refrigeration plant
Contrast test at temperature and each parameter equal state, averagely warm in the stable relief hot blast collection channel of hot-air channel temperature
Degree decreases by 3.9 degree, i.e., per kilowatt 0,43 degree, and, with point detection difference about 4-5 degree, refrigerating efficiency will for its server outlet temperature
It is higher by nearly 30%, it is seen that the refrigeration of the embodiment of the present invention is much better than existing product.
It should be noted that：Treat heat dissipation equipment can be rack, or other any need radiating equipment or
Gas and liquid thermal source, it can be integrated with vaporizer housing, and vaporization chamber housing is also served as treats that heat dissipation equipment installs fixing component,
Also can be separate.
This utility model is for a combination for thermal source load, may also be the group of the same coolant system of different heat sources load
Close, but with thermal source or different heat sources same column parallel combination no more than 3.
When actually used, each vaporizer setting height(from bottom) of parallel combination, size must be consistent, and evaporation tube inlet opening is high
Degree, size must be consistent, ensure the backflow balance of evaporation liquid as far as possible.To same thermal source also can be by a vaporizer bottom above
Liquid collecting room is in series with the common chamber of the collection vapour point liquid of a following vaporizer, by the way of evaporation relay provides more high-power system
Cold.
Evaporation tube 11 is from the copper pipe with female thread or groove (depending on caliber is with thermic load requirement).Evaporation tube overcoat fin 2
From the hydrophilic aluminium foil fin with shutter, increase flow perturbation.
Under same liquid filled ratio, there is the gradient radiating effect meeting of 3-5 degree during evaporation tube right angle setting with vertical line more preferably.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, change or replace that any those familiar with the art is expected in the technical scope that this utility model is disclosed
Change, should all cover within protection domain of the present utility model.
