DETAILED DESCRIPTION
[0019] In order to make the objects, technical solutions and advantages of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.
[0020] It should be noted that when an element is described as "fixed" to another element, it can be directly on the other element or one or more intervening elements can be present therebetween. When an element is described as "connected" to another element, it can be directly connected to the other element or one or more intervening elements can be present therebetween. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", and the like as used in this specification and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0021] As described in the background, in the related art of heat exchange, the heat exchange device has the problems of low heat exchange efficiency of the heat exchanged element, slow heat exchange, and uneven temperature of the heat exchanged element during heat exchange.
[0022] The heat exchanged element includes some frozen elements, such as plastic bottled frozen juice or jam raw materials used in tea shops. These bottled frozen elements need to be thawed to a liquid state before use. The current common thawing method is slow thawing in a refrigerator compartment, which usually takes several hours or even a whole night. For urgent thawing, water thawing is usually used. Water thawing usually consumes a lot of water, and if the thawing amount is large, water thawing is not economical and environmentally friendly. Moreover, water thawing usually needs someone to watch over and adjust the water flow and turn over the bottles in time to ensure uniform thawing, which is time-consuming and labor-intensive. The thawing time is greatly affected by water temperature, water flow, bottle size, and initial freezing temperature. If the operation is improper (such as using too hot water), it will accelerate the quality deterioration of the frozen juice or jam raw materials.
[0023] In addition, the water thawing method is prone to cause uneven temperature of the juice or jam, and the juice or jam can have ice core inside although the outside is already warm. This can make the juice or jam taste thin, and the sweetness and flavor of the juice or jam are not so strong. The ice crystals formed during the freezing process can break the cell walls of the fruit cells, cause the fruit fibers to break, and the fruit pulp or pectin originally suspended to precipitate, thereby causing stratification and uneven texture. The juice can have "grit-water separation" and lose the smooth feeling of the fresh juice.
[0024] The heat exchange device and thawing system provided by the application can thaw the frozen bottled juice or jam without long-time water thawing, reduce waste of water resources, accelerate replacement of energy inside the frozen plastic bottle, accelerate the thawing speed, and ensure the taste of the juice or jam. In addition, the thawing is uniform, and personnel are not required to watch and turn the bottles, thereby saving labor.
[0025] Embodiment one The application provides a heat exchange device, as shown in Figure 2 , Figure 4 , which comprises a heat exchange container 1, heat exchange liquid (not shown), heat exchange columns 2, and a heat exchange assembly 3.

The heat exchange liquid contacts the heat exchanged object 100 and the heat exchange columns 2. The heat exchange container 1 can be a sink basin. When the heat exchanged object 100 needs to be cooled, the heat exchange liquid is a cooling liquid. When the heat exchanged object 100 is a frozen object, the heat exchange liquid is normal temperature water or hot water.
[0026] As shown in Figure 2 , Figure 3 , the heat exchange assembly 3 comprises a heat exchange pipe 31 and a pump element 32 connected to each other. The heat exchange pipe 31 is arranged in an atmospheric environment.

[0027] As shown in Figure 4 , the heat exchange pipe 31 is arranged in the atmospheric environment, and the heat exchange liquid circulates in the heat exchange pipe 31 through the inlet 311 and the outlet 312.As shown, the heat exchange device further comprises a heat exchange column base 4 arranged in the heat exchange container 1, and the heat exchange column 2 comprises a cylindrical column and a square column, the cylindrical column being suitable for a cylindrical heat exchanged object 100, and the square column being suitable for a square heat exchanged object 100, so as to increase the heat exchange area. One end of the heat exchange column 2 is detachably arranged on the heat exchange column base 4, and the arrangement position of the heat exchange column 2 on the heat exchange column base 4 is adjustable to adapt to different heat exchanged objects 100. The heat exchange columns 2 can be uniformly distributed on the heat exchange column base 4. The heat exchange column base 4 can be formed with grooves (not shown) for mounting the heat exchange columns 2, and the grooves can be circular to adapt to the cylindrical column or square to adapt to the square column, so that heat exchange columns 2 of different shapes can be detachably mounted and heat exchange columns 2 at different positions can be detachably mounted, so as to use heat exchanged objects 100 of different shapes and different sizes.
[0028] The heat exchange column 2 is made of high thermal conductivity material (thermal conductivity coefficient ≥ 200 W / (m·K)), which can be a metal such as copper with excellent thermal conductivity.

For example, the two side portions of the serpentine coil 313 protrude out of the heat exchange fins 33, the serpentine coil 313 protruding out of the heat exchange fins 33 can be arranged vertically or obliquely, the first end of the serpentine coil 313 protrudes out of the heat exchange fins 33 and is connected with the liquid inlet 311, and the second end of the serpentine coil 313 protrudes out of the heat exchange fins 33 and is connected with the liquid inlet 311 through the pump element 32. The heat exchange fins 33 can be made of copper or aluminum alloy, and the fin spacing is reasonably set, for example, 2-5 mm, so as to increase the heat exchange area.
[0030] As shown in Figure 5 The heat exchange assembly 3 further comprises a heat exchange fan 34, which is arranged corresponding to the serpentine coil 313 and / or the heat exchange fins 33. The heat exchange fan 34 can be an axial flow fan with adjustable air speed, and is fixed to one side of the serpentine coil 313 and the heat exchange fins 33, and blows air against the serpentine coil 313 and the heat exchange fins 33 to generate forced convection, accelerates the air flow through the serpentine coil 313 and the heat exchange fins 33, and enhances the heat exchange efficiency. The serpentine shape of the serpentine coil 313 can optimize the air duct shape of the heat exchange fan 34, reduce air resistance, and ensure uniform air flow through the serpentine coil 313 and the heat exchange fins 33.
[0031] As shown in Figure 3As shown, the liquid inlet 311 is connected to the bottom of the heat exchange container 1, and the heat exchange liquid in the heat exchange container 1 enters the heat exchange pipe 31 through the liquid inlet 311; the liquid outlet 312 is connected to the top of the heat exchange container 1, and the heat exchange liquid in the heat exchange pipe 31 enters the heat exchange container 1 through the liquid outlet 312. During heat exchange, the cold water with large density is located at the lower part of the heat exchange container 1, and the hot water with small density is located at the upper part of the heat exchange container 1. When the heat exchange member 100 is a freezing member, the cold water at the bottom of the heat exchange container 1 directly enters the heat exchange pipe 31, and after heat exchange through the heat exchange assembly 3, the temperature is increased and then the cold water enters the heat exchange container 1 from the top of the heat exchange container 1. In this way, the cold and hot circulation exchange can be accelerated, and the heat exchange efficiency can be improved.

The above structure can enhance the flowability of the heat exchange liquid, so as to further improve the heat exchange efficiency.
[0033] The heat exchange device further comprises a temperature detection member (not shown) and a controller (not shown) connected thereto. The temperature detection member is used for real-time monitoring of the temperature of the heat exchange member 100 and the temperature of the heat exchange liquid during heat exchange, and the controller is connected to the heat exchange assembly 3. The temperature detection member can adopt a PT100 or a thermocouple sensor, and the controller is connected to the pump element 32 and the heat exchange fan 34. The controller can adjust the speed of the pump element 32 and the rotating speed of the heat exchange fan 34 based on a PID algorithm, so as to realize accurate control of the heat exchange process.

The heat exchange column 2 is closely attached to the heat exchange member 100 for heat exchange. The heat exchange liquid changes in temperature after heat exchange with the heat exchange column 2 and the heat exchange member 100, and then enters the heat exchange pipe 31. The heat exchange liquid exchanges energy with the external air during the flow in the heat exchange pipe 31. The heat exchange fins 33 and the heat exchange fan 34 take away the heat or cold of the heat exchange pipe 31 and the ice water, so as to realize energy exchange. The heat exchange liquid changes in temperature and then returns to the heat exchange container 1. The heat exchange liquid circulates to heat exchange the heat exchange member 100 and continuously provides heat source or cold source for the heat exchange column 2 through convection, so as to avoid the accumulation of heat or cold of the heat exchange column 2, and maintain the stable heat exchange temperature difference of the heat exchange column 2.
