Operation principle of the present utility model is described as follows:
See Fig. 1, when refrigerating chamber 7 temperature is higher, temperature-sensing valve 4 is opened, the many ducted working medium of annular heat pipe become gaseous state at annular heat pipe evaporator section 3 by thermal evaporation, gas rises and enters annular heat pipe condensation segment, and be cooled to liquid state with heat-conducting plate 5 heat exchange, the evaporator section 3 that condensed liquid refrigerant relies on capillary force effect and Action of Gravity Field to be back to annular heat pipe again completes circulation, the cold of refrigerating chamber 6 is delivered in refrigerating chamber 7 by working medium simultaneously, reduces its temperature; When refrigerating chamber 7 temperature is lower, temperature-sensing valve 4 cuts out, and annular heat pipe working medium can not circulate, and the cold of refrigerating chamber 6 can not be delivered in refrigerating chamber 7, then refrigerating chamber 7 temperature is slowly gone up, until temperature-sensing valve 4 is opened again when temperature is higher.Many annular heat pipe high-frequency ground discontinuous are comparatively stable to maintain cold compartment of refrigerator 7 temperature.
See Fig. 1 and Fig. 2, when refrigerating chamber 7 temperature is higher, temperature-sensing valve 4 is opened, the refrigerating chamber 6 of refrigerator uses annular heat pipe mechanism transport portion cold to go to cold compartment of refrigerator 7, by reducing the heat conduction temperature difference in thermal insulation layer between heat-conducting plate and outcase of refrigerator, the cold that the refrigerating chamber 6 reducing refrigerator loses to surroundings; When refrigerating chamber 7 temperature is lower, temperature-sensing valve 4 cuts out, and the cold of refrigerating chamber 6 can not be delivered in refrigerating chamber 7, and at this moment the cold that loses to surroundings of the refrigerating chamber 6 of refrigerator is similar to field ice case.
When refrigerator stable operation, annular heat pipe mechanism also operationally, considers that refrigerating chamber 6 thermal insulation layer inwall and outer wall exist the larger temperature difference, can ignore the variations in temperature of refrigerating chamber 6 thermal insulation layer inwall and outer wall, by its temperature difference △ T=
-
be considered as definite value, and the conduction process in refrigerating chamber 6 thermal insulation layer is considered as steady heat conduction.
Polyurethane foam material 1 thermal conductivity factor is considered as definite value λ, further heat transfer problem in refrigerating chamber 6 thermal insulation layer can be reduced to one dimension steady heal conduction problem.
The temperature of heat-conducting plate 2 should change with variations in temperature in refrigerating chamber 7 in theory, considers that cold transmits resistance and hysteresis quality, the temperature of heat-conducting plate 2 is considered as mean temperature in refrigerating chamber 7
.
Then can make following theoretical analysis and calculation:
See Fig. 3, heat-conducting plate is positioned at inner chamber outer surface to being example during 1/4th place of outcase of refrigerator spacing distance:
See Fig. 4, when heat-conducting plate is positioned at the x(1/8<x<1/3 of inner chamber outer surface to outcase of refrigerator spacing distance) place time be example:
In formula:
for the cold of general refrigerator refrigerating chamber thermal insulation layer unit are loss,
for heat-conducting plate is positioned at the cold that inner chamber outer surface transmits to thermal insulation layer unit are during 1/4th place of outcase of refrigerator spacing distance to refrigerating chamber,
for heat-conducting plate is positioned at the cold of inner chamber outer surface to thermal insulation layer unit are loss during 1/4th place of outcase of refrigerator spacing distance,
for being positioned at the cold that inner chamber outer surface transmits to thermal insulation layer unit are during the x place of outcase of refrigerator spacing distance to refrigerating chamber when heat-conducting plate,
for being positioned at the cold of inner chamber outer surface to thermal insulation layer unit are loss during the x place of outcase of refrigerator spacing distance when heat-conducting plate,
λ is polyurethane foam material thermal conductivity factor,
L is general refrigerator refrigerating chamber thermal insulation layer polyurethane foam material thickness,
for refrigerating chamber thermal insulation layer outside wall temperature,
for refrigerating chamber thermal insulation layer inner wall temperature,
for refrigeration average indoor temperature.
If with refrigerating chamber thermal insulation layer outside wall temperature
be 20 DEG C, refrigerating chamber thermal insulation layer inner wall temperature
for-20 DEG C, refrigeration average indoor temperature
be the ideal situation of 5 DEG C be that example makes simple analysis, heat-conducting plate be positioned at inner chamber outer surface to during 1/4th place of outcase of refrigerator spacing distance its
=2.5
,
=0.5
.Ideally, when heat-conducting plate is positioned at inner chamber outer surface to the x place of outcase of refrigerator spacing distance, the cold that the position of heat-conducting plate in refrigerating chamber thermal insulation layer is transported to cold compartment of refrigerator the closer to refrigerating chamber inner chamber outer surface (namely x is less) annular heat pipe mechanism is more, the cold that freezer compartment of refrigerator loses to surroundings is less, and energy-conservation effect is better.Be positioned at inner chamber outer surface for heat-conducting plate and get 1/4th places to the x of outcase of refrigerator spacing distance, the cold with the freezer compartment of refrigerator thermal insulation layer unit are loss of annular heat pipe mechanism is reduced to 1/2nd of initial value, obviously reduces the loss of refrigeration capacity of freezer compartment of refrigerator; Refrigerating chamber is 10 by four box body walls with heat-conducting plate towards the cold of refrigerating chamber transmission
, consider that family expenses general refrigerator refrigerating chamber is similar to refrigerating chamber cold damage amount, annular heat pipe mechanism can meet the refrigeration requirement of refrigerating chamber completely.
