Abstract
The utility model relates to a heat tube heat exchanger, which can meet the requirement that a heat source is positioned at the upper part of a cold source. The heat exchanger is characterized in that an evaporation apparatus is composed of an evaporation casing, and imbibitions which are embedded in the evaporation casing. A liquid imbibing core can be formed into a hollow body which is composed of a wire mesh and metal powders, or can be formed into a hollow body which is sintered by a micropore molding, and the inner part of the hollow body is injected with working fluid, namely, the acetone. When the heat is imbibed, the working fluid is hoisted and returned under the action of pressure difference formed by the liquid imbibing core, and therefore, the circulation of a vapor and liquid phase transition in a heat pipe. The utility model can be used for cooling electronic components of a semiconductor refrigeration, a semiconductor air conditioner, a spacecraft, etc.
Description
The utility model relates to a kind of heat exchanger, exactly is a kind of antigravity heat exchange of heat pipe.
Existing heat exchange of heat pipe is formed by gravity assisted heat pipe or capillary wick heat pipe.Disclose with many gravity assisted heat pipes as Chinese patent 85103275 and to have inserted in the liquid tank device as the condenser of refrigerator, the gravity assisted heat pipe in this patent, hydraulic fluid refluxes by gravity, can only be used for the heat exchange occasion of thermal source below low-temperature receiver.The capillary wick heat pipe can be used for the heat exchange occasion that thermal source and low-temperature receiver are positioned at same horizontal plane theoretically, and condensation segment that will heat pipe in can practicality is placed in the position that is higher than evaporator section, and heat pipe and horizontal angle are greater than 5 degree.Require thermal source to be positioned at the special heat exchange occasion of low-temperature receiver top for some, can't directly use gravity heat pipe heat exchanger or capillary wick heat exchange of heat pipe.
The purpose of this utility model is: provide a kind of and can satisfy the heat exchange of heat pipe that special heat exchange that thermal source is positioned at low-temperature receiver top certain distance requires.
Its technical solution is as follows: a kind of antigravity heat exchange of heat pipe, form by vaporising device, steam pipe, liquid back pipe, it is characterized in that: vaporising device is made up of the imbibition core in evaporation housing and the embedding evaporation housing, one end of liquid back pipe stretches into housing to imbibition core top by the bottom of evaporation housing, the other end is communicated with steam pipe, and the other end of steam pipe is located at a side of evaporation housing.The imbibition core can be the ducted body of being made up of silk screen and metal dust, or can be the micro molding ducted body of sintering, and wall thickness is even, its outer wall vertically uniform at least two steam grooves, one end of its outer wall is provided with the annular groove of all vertical steam grooves of connection, and the height of imbibition core is lower than the height of evaporation housing.The steam pipe that is located at evaporation housing one side is communicated with imbibition core steam annular groove.The working media that injects in this heat exchanger is an acetone, and injection rate is more than 1/3rd of evaporating space volume.
The utlity model has the advantage that can effectively the heat that is positioned at the thermal source of top directly be reached the low-temperature receiver that is positioned at the below, it is little also to have the heat exchange of heat pipe thermal resistance, and heat-transfer capability is big, the advantage of compact conformation.

Fig. 2 is an A--A cutaway view among Fig. 1.
Reference numeral:
1 evaporation housing, 2 silk screens, 3 metal dusts, 4 liquid storehouses, 5 steam grooves, 6 steam pipes, 7 liquid back pipes, Q heat, L liquid, V steam, G gravity direction.
Below in conjunction with drawings and Examples the utility model is described further.
The utility model is made up of vaporising device, steam pipe 6, liquid back pipe 7, vaporising device is made up of evaporation housing 1 and the imbibition core that embeds in it, evaporation housing 1 material is a red copper, it is long to be 80mm, wide is 60mm, the high 120mm of being, the imbibition core is by 200 ducted bodies of making from above copper mesh 2 and nickel powder 3, wall thickness is even, its outer wall vertically uniform at least two steam grooves 5, one end of its outer wall is provided with the annular groove of all vertical steam grooves 5 of connection, and the height of imbibition core is lower than the height of evaporation housing 1.The cavity that is formed with imbibition core difference in height by evaporation housing 1 is liquid storehouse 4.Diameter is φ 4mm, one end of long liquid back pipe 7 for 1m is stretched in the housing to the liquid storehouse 4 on imbibition core top by the bottom of evaporation housing 1, and the other end and diameter are φ 8mm, long steam pipe 4 connections for 1m, the other end of steam pipe 4 is located at a side of evaporation housing 1, and is communicated with imbibition core steam annular groove.The working media that injects in this heat exchanger is an acetone.Injection rate is more than 1/3rd of evaporating space volume.
When the heat pipe vaporising device when thermal source absorbs heat, liquid storehouse 4 in its evaporation housing 1 and the heat absorption of the working solution in imbibition core rear section become steam, increase along with the working solution caloric receptivity, quantity of steam constantly increases, vapour pressure rises thereupon, steam enters steam pipe 6 along steam groove 5, steam pipe 6 causes the low-temperature receiver place with steam, it is the junction of steam pipe 6 and liquid back pipe 7, steam discharges heat to being condensed into liquid behind the low-temperature receiver with convection current and radiation mode by tube wall in the pipe, this liquid is raised under the effect of the pressure reduction that the imbibition core forms and is back to liquid storehouse 4, and this has just formed the cyclic process of inside heat pipe liquid-gas phase transition (hoisting depth of imbibition core is greater than 0.5m).
The utility model can be used for semiconductor refrigerating, as condenser as refrigerator, the antigravity heat pipe directly is connected with the hot side of 40W semiconductor chilling plate, thermal source is positioned at low-temperature receiver top certain distance, the dischargeable capacity of refrigerator is 40 liters, in environment temperature is under 12 ℃ of situations of switching on 30 minutes continuously, can make the refrigeration in-cabinet temperature reach 3 ℃.The utility model also can be used for semiconductor air conditioner, the heat exchanger of aspects such as Spacecraft Electronic components and parts cooling.
