Fig. 4,5 are referred to, is solid combination and the combination section view of the first embodiment of the utility model loop circuit heat pipe, such as schemes
Shown, the capillary structure in the utility model loop circuit heat pipe implements explanation and illustrates embodiment with foregoing capillary structure first embodiment
It is identical, therefore will not be described in great detail herein, only the present embodiment is in the loop circuit heat pipe 2 with foregoing capillary structure embodiment difference,
Comprising：One evaporation cavity 21, a capillary structure 1, one condensation body 22, a working fluid 23；
The evaporation cavity 21 has an accommodation space 211 and an outlet 211 and an entrance 212, the entry and exit 212,
213 are divided into the rear and front end of evaporation cavity 21, and the evaporation cavity 21 can rounded, square, paddle type any of which.
The capillary structure 1 is arranged in aforementioned evaporation cavity 21, the capillary structure 1, comprising：One body 11 has plural number
Groove 111, the groove 111 is arranged at the outer peripheral edge of body 11 and along the axially extending institute's configuration of the body 11, and the groove 111 has
One open sides 1111 and a closed side 1112, the width of open sides 1111 are less than the width of closed side 1112.
The condensation body 22 has a first end 221 and one second end 222, crosses first and second end 221,222 and connects respectively
Connect string outside outlet 211 and the entrance 212 of the evaporation cavity 21, the condenser pipe body and be cased with plurality of radiating fins 223 as increasing
Plus condensation efficiency is used, the radiating fin 223 is also replaceable for plural number radiating body, and the working fluid 23 is filled in foregoing
In evaporation cavity 21, the working fluid 231 being partly in a liquid state is stayed in the condensation body 22 being put without working condition.
The open sides 1111 of the groove 111 of the capillary structure 1 are attached at the wall of the evaporation cavity 21, and the evaporation cavity
21 with more a vapor cavity 213 and a compensation chamber 214, and the vapor cavity 213 and the compensation chamber 214 are by the evaporation cavity
21 define institute's configuration jointly with the body 11 of the capillary structure 1, because the capillary structure 1 is arranged in the evaporation cavity 21, therefore will
The evaporation cavity 21 is defined as the compensation chamber 214 close to one end of entrance 212, and one end close to the outlet 211 is defined as
The vapor cavity 213.
The vapor cavity 213 prevents the working fluid 231 of liquid mainly as the function of the steam precompressed of evaporation cavity 214
In reverse reflux to evaporation cavity 21, the smooth degree for keeping the whole work efficiency of loop circuit heat pipe 2 and steam-condensate circulating is used.
Referring to Fig. 6, being the illustrative view of the utility model loop circuit heat pipe, as illustrated, the utility model loop is warm
The main Pervaporation cavity 21 of pipe 2 at least side or overall contacted with a pyrotoxin 3 conduct heat, when evaporation cavity 21 and heating
During the contact conduction heat of source 3, the heat produced by the absorption pyrotoxin 3 of evaporation cavity 21, further heating is arranged at evaporation cavity
The working fluid 231 of liquid inside 21, and when be stored in the working fluid 231 that is in a liquid state in capillary structure 1 be heated by
When liquid is converted to steam state, it can be provided through the groove 111 of the outer rim located at the capillary structure 1 in the working fluid 232 of steam state
Condensation cycle should be diffused in the flowing of working fluid 231 of steam state, and due to this case in order to which the universe burning for improving capillary structure 1 is asked
Topic, the width of open sides 1111 of the groove 111 is set and is less than the width of closed side 1112, then represents that the capillary structure 1 is whole
Body volume can be increased, and the face of the side contacted with pyrotoxin 3 connects and is also incremented by, and then it is overall to increase capillary structure 1
Water content and increase capillary structure 1 and evaporation cavity 21 wall contact area, and reduce heat transfer thermal resistance.
