Abstract
The invention relates to the field of energy and power, in particular to a frost-proof cooling unit. The frost-proof cooling unit comprises a cooler, wherein a pulse control valve is arranged at an outlet and / or an inlet of a heat absorbing fluid channel of the cooler. The frost-proof cooling unit is simple in structure, high in efficiency, low in manufacturing cost and long in service life.
Description
Technical field
The present invention relates to energy and power engineering field, particularly a kind ofly keep away white cooling unit.
Background technology
In heat power and field of chemical engineering, there are a large amount of cooling operating units containing humid gas, and in cooling procedure, tend to produce frost and ice, thereby have a strong impact on cooling effect, even make cooler stop up cisco unity malfunction, therefore, need to invent a kind of novel containing humid gas cooler.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the technical scheme that the present invention proposes is as follows:
Keep away a white cooling unit, comprise cooler, in outlet and/or the porch of the heat recipient fluid passage of described cooler, establish pulse control valve.
The wall thickness of described heat recipient fluid passage is made as and is less than 1mm.
In the present invention, for the efficiency of keeping away white cooling unit described in improving, should select thermal capacity is low as far as possible, thermal conductivity is high material as the wall of heat recipient fluid passage, can reduce like this wall of heat recipient fluid passage with the degree of hysteresis of wall both sides fluid temperature variations.
Principle of the present invention is: by described pulse control valve, control flowing of heat recipient fluid, the frost or the ice that are attached to heat recipient fluid passage outer surface are melted rapidly, thereby prevent from affecting because of frost or ice the normal work of cooler.
Of the present inventionly keep away white cooling unit, can be used in thermal power system cooling to carrying out containing humid gas, also can be used in aero-engine cooling to carrying out containing humid gas, thereby improve the efficiency of engine.
In the present invention, the wall thickness of described heat recipient fluid passage is made as and is less than 1mm, 0.9mm, 0.8mm, 0.7mm, 0.6mm, 0.5mm, 0.4mm, 0.3mm, 0.2mm or is less than 0.1mm.
In the present invention, should, according to the known technology in energy and power engineering field, in necessary place, necessary parts, unit or system be set.
Beneficial effect of the present invention is as follows:
Of the present inventionly keep away white cooling unit, simple in structure, efficiency is high, cost is low, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1,
In figure:
1 cooler, 2 pulse control valves.
The specific embodiment
Embodiment 1
As shown in Figure 1 keep away white cooling unit, comprise cooler 1, pulse control valve 2 is all established in outlet and porch at the heat recipient fluid passage of described cooler 1, and the wall thickness of described heat recipient fluid passage is made as and is less than 1mm, and the wall thickness of the passage of heat recipient fluid described in figure is made as 0.5mm.
Convertible ground, only establishes pulse control valve 2 or only in the porch of the heat recipient fluid passage of described cooler 1, establishes pulse control valve 2 in the exit of the heat recipient fluid passage of described cooler 1.
Convertible ground, the wall thickness of described heat recipient fluid passage changes to be made as and is less than 1mm, 0.9mm, 0.8mm, 0.7mm, 0.6mm, 0.4mm, 0.3mm, 0.2mm or is less than 0.1mm, certainly, also can the wall thickness of described heat recipient fluid passage not made to restriction.
Of the present invention when keeping away white cooling unit and normally working, the described pulse control valve 2 of establishing is in opening, when needs defrost deicing, the described pulse control valve 2 of establishing is closed or reduces break-make or the flow that opening degree is controlled heat recipient fluid in described heat recipient fluid passage, be attached to the frost of described heat recipient fluid passage outer surface or ice and melted rapidly by the hot fluid that need to be cooled containing humid gas etc. in described heat absorption circulation road flows outside, thereby prevent from affecting because of frost or ice the normal work of cooler.
Obviously, the invention is not restricted to above embodiment, according to the known technology of this area and technical scheme disclosed in this invention, can derive or association goes out many flexible programs, all these flexible programs, also should think protection scope of the present invention.
Claims (2)
1. keep away a white cooling unit, comprise cooler (1), it is characterized in that: pulse control valve (2) is established in outlet and/or porch at the heat recipient fluid passage of described cooler (1).
2. keep away as claimed in claim 1 white cooling unit, it is characterized in that: the wall thickness of described heat recipient fluid passage is made as and is less than 1mm.
