The repetitive description thereof will be omitted.
(embodiment 1)
Fig. 1 is the perspective view of the heat exchange cabinet 100 of the embodiments of the present invention 1, and Fig. 2 is the heat exchange case
The cross-sectional view of body 100.As shown in Figure 1 and Figure 2, heat exchange includes shell 110 with cabinet 100 and is detachably mounted on
Lid 120 on shell 110.In heat exchange with the inside of cabinet 100 with the heat exchange for carrying out the heat exchange of article
Space 140, the heat exchange space 140 are defined by shell 110, that is to say, that are handed over by the space that shell 110 surrounds for heat
Change space 140.Lid 120 closes the heat exchange space 140 limited by shell 110.Lid 120 can by with it is (not shown)
The buckle being arranged on shell 110 engages and is fixed on shell 110, magnetic can also be arranged between shell 110 and lid 120
Property body they are fixed together, but lid 120 and the fixed form of shell 110 are without being limited thereto, can also be used it is other often
Use fixing means.
In present embodiment 1, it is in rectangular shape that heat exchange is whole with cabinet 100, shell 110 have 1 bottom surface and
4 sides with plane perpendicular on bottom surface are set, but the utility model is without being limited thereto, heat exchange cabinet can also basis
It needs to be arranged to arbitrary shape, as long as having the heat exchange space for the heat exchange that can carry out article, shell inside it
It can have any number of bottom surface and side, can not also be open upwards, and be open to other directions, lid can not also
The top of shell is set, can be appropriately arranged with according to the aperture position of shell.
As shown in Fig. 2, the shell 110 of heat exchange cabinet 100 is with the inner wall layer 111 for being located inside and to be located at outside
Outer wall layer 112 double-layer structure, and air intake passage 113 is formed between inner wall layer 111 and outer wall layer 112.Herein, it enters the wind
Channel 113 can be arranged to one interconnectedly, can also be independently set to being spaced from each other multiple.
Outer wall layer 112 be provided with can make external heat exchange entered with gas in multiple air intake passages 113 into
Air port 114 is provided with the air outlet 115 of multiple connection air intake passages 113 and heat exchange space 140 in inner wall layer 111, as a result,
Multiple air inlets between inner wall layer 111 and outer wall layer 112 are entered via air inlet 114 from external heat exchange gas to lead to
In road 113, entered in heat exchange space 140 via the air outlet 115 that inner wall layer 111 is arranged in again later, thus with placement
Article in heat exchange space 140 of the heat exchange with cabinet 100 carries out heat exchange, to cool down article or heating article.
In present embodiment 1, lid 120 also has double-layer structure, and lid return air channel is formed in lid 120
122, and including the first return air inlet 121 to heat exchange 100 inside opening of cabinet and to 100 outer openings of heat exchange cabinet
The second return air inlet 123, lid return air channel 122 is connected to the first return air inlet 121 and the second return air inlet 123.Heat exchange is empty as a result,
Between gas after heat exchange in 140 can be successively via the first return air inlet 121, lid return air channel 122 and the second return air inlet 123
Back to the heat exchange outside of cabinet 100.
Bottom surface and 3 sides in addition to the side for being provided with air inlet 114 is arranged in as shown in Figure 2 in air outlet 115, but

It is interior such as refrigerating chamber 510, temperature-changing chamber 520 and freezing chamber 530 between carry out the air duct 550 of gas circulation.Cooling end 540
It such as include evaporator and fan, the cooling gas generated in evaporator is blown into each via air duct 550 using fan
Room.The body interior of refrigerator 500 is arranged in air duct 550, such as can be set on the wall surface of each compartment.
Air duct 550 includes air-supply passage and return air channel.The cooling gas that air-supply passage is used to be generated by evaporator is defeated
The multiple compartments being sent in refrigerator 500, return air channel are used to multiple indoor gas sending back to cooling end 540.In ice
It is additionally provided in the compartment of case 500：Be connected to the air-supply passage in air duct 550, and opening size and heat exchange cabinet 100 into
The corresponding air outlet 560 in air port 114；It is connected to with the return air channel in air duct 550, and opening size and heat exchange cabinet
The 100 corresponding return air channel opening 570 of the second return air inlet 123.Heat exchange is with cabinet 100 with its air inlet 114 and refrigerator
The mode that 500 air outlet 560 docks is removably mountable in the compartment of refrigerator 500, and thus, it is possible to will flow in air-supply passage
Logical cooling gas is inducted into the heat exchange space 140 of heat exchange cabinet 100, uses cabinet 100 as quickly cooling heat exchange
Room come using.When heat exchange cabinet 100 is installed on the compartment of refrigerator 500, the second return air inlet of heat exchange cabinet 100
123 can also dock with the return air channel of refrigerator 500 opening 570, and the gas after the heat exchange in heat exchange space 140 is sent back to
Into the return air channel of refrigerator 500.
In addition, being provided with fan 130 in the air inlet 114 of heat exchange cabinet 100, but the utility model is not in Fig. 3
It is limited to this, such as fan can not also be set in the air inlet 114 of heat exchange cabinet 100, and in the air outlet of refrigerator 500
560 setting fans.
In Fig. 4, heat exchange cabinet 100 is installed in the refrigerating chamber 510 of refrigerator 500, but the utility model is not limited to
This, such as also can according to need and be mounted in other compartments such as temperature-changing chamber 520 or freezing chamber 530.
Air outlet 560 and return air channel opening 570 are also not necessarily limited to that a compartment of refrigerator 500 is arranged in, and can need to pacify
It fills and is respectively provided with above-mentioned air outlet 560 and return air channel opening 570 in multiple compartments of the refrigerator 500 of heat exchange cabinet 100.Ice
Case 500 also has the baffle that can open and close air outlet 560 and return air channel opening 570, uses being fitted without heat exchange
When cabinet 100, air outlet 560 and return air channel opening 570 can be closed with baffle.
By the above-mentioned heat exchange cabinet 100 of present embodiment 1 and the refrigerator of the heat exchange cabinet 100 is installed
500, heat exchange gas can be blowed to the article being placed in heat exchange space 140 from multiple directions, so that the heat of article
Exchange efficiency greatly improves, and does not need in addition to increase evaporator, can be realized the simplification of structure, and reduce manufacturing cost.
Moreover, the heat exchange of the utility model is removable relative to refrigerator with cabinet 100, therefore can be arranged according to the needs of users
The different compartments of refrigerator, can flexibly use, and improve convenience.Further, it is also possible to as needed, to heat exchange cabinet 100
Supply lower temperature gas come as snap-chill cabinet, or to heat exchange with cabinet 100 supply higher temperature gas by
It comes as defrosting room using can be realized multiple functions.
(embodiment 2)
The embodiments of the present invention 2 is related to a kind of heat exchange cabinet 200, and the heat exchange with embodiment 1 is used
The difference of cabinet 100 is that the second return air inlet 223 of heat exchange cabinet 200 is not open with the return air channel of refrigerator 500
570 docking.The other structures of embodiment 2 are identical with cabinet 100 as the heat exchange of embodiment 1, and description will be omitted.
Fig. 5 is the cross-sectional view of the heat exchange cabinet 200 of the embodiments of the present invention 2.As shown in figure 5, heat exchange
