The pan 100 of the present embodiment five also has following additional technical feature.

In certain embodiments, thermal deformation component can include：Seal assembly and thermal deformation part 5, seal assembly be located at every In hot chamber 3, the lower edge of seal assembly and the inner surface of outer courage 2 are tightly connected, and are limited between the inner surface of seal assembly and outer courage 2 Make holding tank 8, and the adjustable volume of holding tank 8.The optional position on the upper edge of holding tank 8 is not less than the bottom surface of inner bag 1, That is holding tank 8 on be bonded along the bottom surface completely with inner bag 1.When heat-conducting block 4 is located at first state, holding tank has First volume (such as volume of the holding tank shown in Figure 13), the heat-conducting block 4 for being suitable for solid-state contact outer courage 2 and inner bag 1, real Existing heat transfer.When heat-conducting block 4 is located at the second state, holding tank has the second volume (such as holding tank shown in Figure 14 Volume), the heat-conducting block 4 for being suitable for liquid separates with inner bag 1, the not heat conduction of heat-conducting block 4, and the first volume is less than the second volume；Heat Deformable member 5 is connected with seal assembly, and thermal deformation part 5 is used for the volume for changing holding tank 8.

Further, seal assembly can include multiple sealing blocks 7, and multiple sealing blocks 7 coordinate with inner bag 1 and outer courage 2 to be limited Holding tank 8 is made, multiple sealing blocks 7 can include at least one movable seal block 7 for being suitable to change the volume of holding tank, That is multiple sealing blocks 7 can only include a movable seal block 7, only one movable seal block 7 is used for by movement Change the volume of holding tank 8, multiple sealings can also include the movable seal block 7 of two, three or four and the above, lead to soon Cross move two, three, four and the above movable seal block 7 can be used for change holding tank 8 volume.Thermal deformation part 5 It can be connected with movable seal block 7, thermal deformation part 5 is used to drive movable seal block 7 to move, to change the body of holding tank 8 Product.

With reference to Figure 13 and Figure 14, when heat-conducting block 4 is in first state, heat-conducting block 4 is solid, and heat-conducting block 4 is filled up completely with First volume of full whole holding tank 8, heat-conducting block 4 contact realization heat transfer with inner bag 1 and outer courage 2 respectively.When temperature reaches predetermined During temperature, it be liquid that heat-conducting block 4, which melts, and the second volume due to accommodating liquid heat conductive block 4 is more than the of receiving solid-state heat-conducting block 4 One volume, therefore, liquid heat conductive block 4 can not be completely filled with the holding tank with the second volume, and so, the heat-conducting block 4 of liquid is then It can not be contacted with the bottom wall of inner bag 1, it is impossible to realize heat transfer.

Advantageously, as shown in figure 13, seal assembly can include two sealing blocks 7, and two sealing blocks 7 are positioned opposite, and Two sealing blocks 7 (such as direction towards inner bag 1 and the central axis of outer courage 2) close to each other and remote direction (such as In the radially outward direction along inner bag 1 or outer courage 2) on may move, thermal deformation part 5 is connected with least one sealing block 7, also It is to say, thermal deformation part 5 only can be connected with a sealing block 7, and thermal deformation part 5 can also be connected with two sealing blocks 7.When heat becomes When shape part 5 deforms, thermal deformation part 5 can drive sealing block 7 close to each other or remote, so as to realize holding tank 8 first Switching between volume and the second volume.

Further, in certain embodiments, thermal deformation part 5 can be located between two sealing blocks 7, and thermal deformation part 5 can To be connected respectively with two sealing blocks 7, thermal deformation part 5 is configured to promote two phases of sealing block 7 when temperature is higher than predetermined temperature It is mutually remote.That is, when temperature is higher than predetermined temperature, it is liquid that heat-conducting block 4 melts from solid-state, meanwhile, thermal deformation part 5 is sent out Change shape, promotes two sealing blocks 7 to be located remotely from each other so that holding tank 8 increases to the second volume, liquid heat conductive block from the first volume 4 separate with inner bag, not heat conduction.

Preferably, thermal deformation part 5, which can be configured to extend when temperature is increased to predetermined temperature, is not less than 0.1 millimeter, In other words, when temperature is increased to predetermined temperature, thermal deformation part 5 extends at least 0.1 millimeter, and thus, thermal deformation part 5 can promote Two sealing blocks 7 are located remotely from each other at least 0.1 millimeter, so that the first volume of holding tank 8 increases to the second volume.

In further embodiments, thermal deformation part 5 can also be located at the outside of two sealing blocks 7, and the one of thermal deformation part 5 End is connected with sealing block 7, and the other end of thermal deformation part 5 is connected with outer courage 2 or inner bag 1, and thermal deformation part 5 can be configured in temperature Two sealing blocks 7 are pulled to be located remotely from each other when degree is higher than predetermined temperature.Further, thermal deformation part 5 can be configured in temperature Shorten when being increased to predetermined temperature and be not less than 0.1 millimeter.

Specifically, when temperature is increased to predetermined temperature, it is liquid that heat-conducting block 4 melts from solid-state, while thermal deformation part 5 is sent out Raw deformation, shortens at least 0.1 millimeter, and now, thermal deformation part 5 can pull two seals to be located remotely from each other at least 0.2 millimeter, from And make holding tank that there is the second bigger volume of volume so that liquid heat conductive block 4 separates with inner bag 1, not heat conduction.

In certain embodiments, multiple sealing blocks 7 can be located between the bottom wall of inner bag 1 and the bottom wall of outer courage 2, and multiple It is connected between sealing block 7 yielding section (not shown).It is variable when thermal deformation part 5 pulls at least one sealing block 7 to move Shape section can deform upon, and to ensure that multiple sealing blocks 7 are connected all the time, thus, multiple sealing blocks 7 can be with inner bag 1 and outer courage 2 The holding tank of adjustable volume is limited jointly, to avoid breaking between sealing block 7 and sealing block 7, or avoids sealing block 7 and sealing Deformation can not be recovered between block 7, avoid the heat-conducting block 4 of liquid from leaking.

In certain embodiments, when heat-conducting block 4 is located at first state, the gap ratio heat-conducting block 4 of two sealing blocks 7 is located at Spacing during the second state between two sealing blocks 7 is small at least 0.1 millimeter.Thus, just can guarantee that when heat-conducting block 4 is from first state Switch to the second state, when solid-state is molten into liquid, be effectively spaced apart between heat-conducting block 4 and inner bag 1, heat-conducting block 4 and inner bag 1 Between not heat conduction.

Alternatively, thermal deformation component can include one or more.

Due to heat-conducting block 4 from first state switch to the second state when, heat-conducting block 4 is changed into liquid from solid, but this reality With the predetermined temperature of new embodiment in the range of 120 DEG C to 300 DEG C, it is therefore preferred that heat-conducting block 4 is low melting point heat conduction Block 4, specifically, heat-conducting block 4 can be heat-conducting block 4 of the fusing point between 120 degrees Celsius to 300 degrees Celsius.Such as heat-conducting block 4 can Think the heat-conducting metal block of low melting point.
