Description

Technical Field

[0001] This application relates to the field of refrigeration technology, specifically to an evaporator and refrigeration equipment. Background Technology

[0002] In the field of refrigeration, the evaporator, as one of the components of the refrigeration system, absorbs heat through the evaporation process of the refrigerant, thereby achieving a cooling effect on the surrounding environment or a specific space.

[0003] Existing evaporators typically employ conventional structures such as spiral copper tubes or fins, positioned between an inner and outer cooling liner. The object to be cooled is placed inside the inner liner. However, these structures have limited or no contact area with the inner liner. For example, when a spiral copper tube is positioned between the inner and outer liner, the contact area is limited to a single spiral line; similarly, when fins are positioned between the inner and outer liner, they do not contact the inner liner. Consequently, heat transfer efficiency is low, resulting in poor cooling efficiency. Utility Model Content

[0004] One objective of this application is to provide an evaporator to solve the problem of low refrigeration efficiency.

[0005] Another object of this application is to provide a refrigeration device.

[0006] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: an evaporator, comprising a shell and a refrigerant section disposed within the shell, the refrigerant section comprising an upper end, a lower end, a plurality of first tubes and a plurality of second tubes, the first tubes and the second tubes being alternately arranged around the inner wall of the shell, the first tubes and the second tubes respectively enclosing and defining a first channel and a second channel with the shell, the upper end comprising a plurality of independent upper cavities, the lower end comprising a plurality of independent lower cavities, the top end of the first tube and the top end of an adjacent second tube being connected to the upper cavity, the bottom end of the first tube and the bottom end of an adjacent second tube being connected to the lower cavity, thereby each first channel and each second channel being connected by the upper cavity and the lower cavity to form the refrigerant channel.

[0007] As a preferred embodiment, both the first tube and the second tube extend axially along the housing.

[0008] As another preferred embodiment, both the first tube and the second tube have semi-circular cross-sections.

[0009] Further preferably, a partition is provided in one of the upper cavities at the upper end, the partition defining the upper cavity into two independent inflow cavities and outflow cavities, the inflow cavity being connected to the top end of a first tube, the outflow cavity being connected to the top end of a second tube, and the upper end also having an inlet and an outlet, the inlet being provided corresponding to the inflow cavity, and the outlet being provided corresponding to the outflow cavity; Alternatively, a partition is provided in one of the lower cavities at the lower end, which defines the lower cavity as two independent inflow cavities and outflow cavities. The inflow cavity is connected to the bottom end of one of the first tubes, and the outflow cavity is connected to the bottom end of one of the second tubes. An inlet and an outlet are also provided on the lower end, with the inlet corresponding to the inflow cavity and the outlet corresponding to the outflow cavity.

[0010] Furthermore, the evaporator also includes a refrigerant inlet pipe and a refrigerant outlet pipe, the refrigerant inlet pipe being adapted to connect with the inlet to communicate with the inflow chamber, and the refrigerant outlet pipe being adapted to connect with the outlet to communicate with the outflow chamber.

[0011] Furthermore, the housing includes an outer wall and a bottom wall disposed at the bottom end of the outer wall. The outer wall has a cylindrical structure and is hollow inside. The bottom wall has an annular structure. The upper end is adapted to enclose and define the upper cavity with the outer wall, and the lower end is adapted to enclose and define the lower cavity with the outer wall and the bottom wall.

[0012] Furthermore, the upper end portion includes a first end wall, a second end wall, and a third side wall. The first end wall and the second end wall extend radially along the housing, and the third side wall extends axially along the housing. The first end wall and the second end wall are respectively disposed at the top and bottom ends of the third side wall. A plurality of partition walls are also disposed between the first end wall, the second end wall, the third side wall, and the third side wall. Thus, the first end wall, the second end wall, the third side wall, and the partition walls, together with the outer wall, enclose and define each of the upper cavities.

[0013] Furthermore, the lower end portion includes a fourth end wall and a fifth side wall. The fourth end wall extends radially along the housing, and the fifth side wall extends axially along the housing. The fourth end wall is disposed at the top of the fifth side wall. A plurality of isolation walls are also disposed between the fourth end wall and the fifth side wall. Thus, the fourth end wall, the fifth side wall, and the isolation walls, together with the outer wall and the bottom wall, enclose and define each of the lower cavities.

[0014] Furthermore, the diameters of the first and second pipe bodies can be implemented as 7mm to 10mm.

[0015] To achieve at least one of the above objectives, the technical solution adopted in this application is: a refrigeration device, including a body, wherein the evaporator described above is disposed within the body.

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] like Figure 1-5 As shown, this application provides an evaporator, which includes a housing 100 and a refrigerant section 200 disposed within the housing 100. The housing 100 and the refrigerant section 200 enclose and define a refrigerant channel, in which refrigerant can flow to cool the object to be cooled.

[0028] The housing 100 includes an outer wall 110 and a bottom wall 120 disposed at the bottom end of the outer wall 110. The outer wall 110 has a cylindrical structure and is hollow inside, while the bottom wall 120 has a ring-shaped structure. The outer wall 110 and the bottom wall 120 together form a cylindrical space, within which the object to be cooled can be placed. A refrigerant section 200 is disposed within the cylindrical space. The refrigerant section 200 includes an upper end 210, a lower end 220, a plurality of first tubes 230, and a plurality of second tubes 240. The plurality of first tubes 230 and the plurality of second tubes 240 are alternately arranged around the inner side of the outer wall 110. The first tubes 230 and the outer wall 110 enclose and define a first channel, and the second tubes 240 and the outer wall 110 enclose and define a second channel. The upper end 210 is connected to the top ends of the first tubes 230 and the second tubes 240, and the lower end 220 is connected to the first tubes 230 and 240. The bottom end of the first tube 230 and the bottom end of the second tube 240 are connected to the upper end 210, which includes multiple independent upper cavities 211, and the lower end 220, which includes multiple independent lower cavities 221. The top end of the first tube 230 and the top end of the adjacent second tube 240 are connected to the upper cavity 211, and the bottom end of the first tube 230 and the bottom end of the adjacent second tube 240 are connected to the lower cavity 221. Thus, each first channel and each second channel are connected by the upper cavity 211 and the lower cavity 221 to form a refrigerant channel for refrigerant flow. The object to be cooled (such as drinking water) placed in the cylindrical space can directly contact the first tube 230 and the second tube 240. The evaporation process of the refrigerant in the refrigerant channel can fully interact with the object to be cooled, thereby improving the cooling effect of the object to be cooled and rapidly reducing the temperature of the object to be cooled in a relatively short time (e.g., cooling drinking water into ice).

[0029] Furthermore, both the first tube 230 and the second tube 240 extend along the axial direction of the housing 100, and the cross-sections of both the first tube 230 and the second tube 240 are semi-circular. The semi-circular cross-sections of the first tube 230 and the second tube 240 allow for a larger contact area between the object to be cooled and the first tube 230 and the second tube 240, while ensuring the size of the refrigerant channel, thus enhancing the efficiency of heat exchange.

[0030] In some preferred embodiments, the diameters of the first tube 230 and the second tube 240 can be 7 mm to 10 mm. More preferably, the diameters of the first tube 230 and the second tube 240 can be 9 mm.

[0031] Furthermore, the upper end portion 210 includes a first end wall 212, a second end wall 213, and a third side wall 214. The first end wall 212 and the second end wall 213 extend radially along the housing 100, and the third side wall 214 extends axially along the housing 100. The first end wall 212 and the second end wall 213 are respectively disposed at the top and bottom ends of the third side wall 214, so that the cross section of the upper end portion 210 has a U-shaped structure. The upper end portion 210 is disposed on the inner side of the outer wall 110, and thus the first end wall 212, the second end wall 213, and the third side wall 214 together with the outer wall 110 define a cavity. The upper end 210 also includes a plurality of partition walls 215, which are connected to the first end wall 212, the second end wall 213 and the third side wall 214, and the partition walls 215 are adapted to be sealed to the outer wall 110. Thus, the partition walls 215 divide the cavity into a plurality of independent upper cavities 211, and the top end of the first channel and the top end of the adjacent second channel can communicate with each other through the upper cavity 211.

[0032] Furthermore, the lower end portion 220 includes a fourth end wall 222 and a fifth side wall 223. The fourth end wall 222 extends radially along the housing 100, and the fifth side wall 223 extends axially along the housing 100. The fourth end wall 222 is disposed at the top of the fifth side wall 223, making the cross-section of the lower end portion 220 L-shaped. The lower end portion 220 is disposed inside the outer wall 110, thereby the fourth end wall 222 and the fifth side wall 223, together with the outer wall 110 and the bottom wall 120, define a cavity. The lower end portion 220 also includes a plurality of isolation walls 224. The isolation walls 224 are connected to the fourth end wall 222 and the fifth side wall 223, and the isolation walls 224 are adapted to be sealed to the outer wall 110 and the bottom wall 120. Thus, the isolation walls 224 divide the cavity into a plurality of independent lower cavities 221. The bottom end of the first channel and the bottom end of an adjacent second channel can communicate with each other through the lower cavities 221.

[0033] Furthermore, a partition 250 is provided in one of the upper cavities 211 of the upper end 210. The partition 250 divides the upper cavity 211 into two independent cavities. One side of the partition 250 forms an inflow cavity 260, and the other side of the partition 250 forms an outflow cavity 270. The inflow cavity 260 is connected to the top end of the first tube 230, and the outflow cavity 270 is connected to the top end of the second tube 240. An inlet and an outlet are also provided on the upper end 210. The inlet is correspondingly provided on the wall of the inflow cavity 260, and the outlet is correspondingly provided on the wall of the outflow cavity 270. The evaporator also includes a refrigerant inlet pipe 300 and a refrigerant outlet pipe 400. The refrigerant inlet pipe 300 is adapted to be connected to the inlet so that the refrigerant inlet pipe 300 is connected to the first channel, and the refrigerant outlet pipe 400 is adapted to be connected to the outlet so that the refrigerant outlet pipe 400 is connected to the second channel. That is, the refrigerant inlet pipe 300 is connected to the inlet end of the refrigerant channel, and the refrigerant outlet pipe 400 is connected to the outlet end of the refrigerant channel. Refrigerant can flow into the refrigerant channel through the refrigerant inlet pipe 300 and can flow out of the refrigerant channel through the refrigerant outlet pipe 400.

[0034] Optionally, in some other embodiments, a partition 250 is provided in one of the lower cavities 221 of the lower end 220. The partition 250 divides the lower cavity 221 into two independent cavities. One side of the partition 250 forms an inflow cavity 260, and the other side of the partition 250 forms an outflow cavity 270. The inflow cavity 260 is connected to the bottom end of the first tube 230, and the outflow cavity 270 is connected to the bottom end of the second tube 240. The lower end 220 is also provided with an inlet and an outlet. The inlet is correspondingly provided on the wall of the inflow cavity 260, and the outlet is correspondingly provided on the wall of the outflow cavity 270. The evaporator also includes a refrigerant inlet pipe 300 and a refrigerant outlet pipe 400. The refrigerant inlet pipe 300 is adapted to be connected to the inlet so that the refrigerant inlet pipe 300 is connected to the first channel, and the refrigerant outlet pipe 400 is adapted to be connected to the outlet so that the refrigerant outlet pipe 400 is connected to the second channel. That is, the refrigerant inlet pipe 300 is connected to the inlet end of the refrigerant channel, and the refrigerant outlet pipe 400 is connected to the outlet end of the refrigerant channel. Refrigerant can flow into the refrigerant channel through the refrigerant inlet pipe 300 and can flow out of the refrigerant channel through the refrigerant outlet pipe 400.
