Referring to fig. 1-10, heat exchange unit 101 is shown in various embodiments. The heat exchange unit 101 comprises a main body 102, the main body 102 is provided with a flow channel 901, and a heat exchange medium can flow in the flow channel 901; heat exchange unit 101 further includes first connector 301 and/or connecting channel 103, first connector 301 is connected to main body 102, connecting channel 103 is opened on main body 102, and first connector 301 of one heat exchange unit 101 can enter and exit connecting channel 103 of another heat exchange unit 101.

Some possible arrangements of the first connection body 301 and the connection channel 103 are described in detail below. Referring to fig. 1, which shows a heat exchange unit 101 in some embodiments, the heat exchange unit 101 shown in fig. 1 is provided with only the connection channels 103, the first connection body 301 is not provided, and the connection channels 103 provided on the main body 102 are groove-shaped. Referring to fig. 3, illustrating heat exchange unit 101 in other embodiments, heat exchange unit 101 shown in fig. 3 is provided with only first connection body 301, without connection channel 103, and first connection body 301 is provided as a strip-shaped protrusion. Fig. 5 and 7 show the heat exchange unit 101 provided with both the first connection body 301 and the connection channel 103, the first connection body 301 and the connection channel 103 being provided on different wall surfaces of the main body 102; in fig. 5, the first connection body 301 and the connection passage 103 are provided on the opposite wall surfaces of the main body 102; in fig. 7, the first connection body 301 and the connection passage 103 are provided on two adjacent wall surfaces of the main body 102.

First connection body 301 on one heat exchange unit 101 may be connected with connection channel 103 on another heat exchange unit 101, taking connection between heat exchange unit 101 shown in fig. 1 and heat exchange unit 101 shown in fig. 3 as an example: firstly, turning the heat exchange unit 101 shown in fig. 3 upside down to make the first connector 301 face downward (the position state of the heat exchange unit 101 shown in fig. 1 is kept unchanged), then inserting the first connector 301 from the rightmost end of the connecting channel 103, and moving the first connector 301 until the end of the first connector 301 abuts against the wall surface at the leftmost side of the connecting channel 103; due to the obstruction of the wall surface of the connection channel 103, the first connection body 301 cannot move in the depth direction of the connection channel 103 to leave the connection channel 103, and the fixation between the heat exchange units 101 is achieved. Taking fig. 1 as an example, the depth direction of the connecting channel 103 referred to herein corresponds to the up-down direction in fig. 1.

In some embodiments, the heat exchanging unit 101 may be configured such that the wall surface of the connecting channel 103 can abut against the first connecting body 301 to block the first connecting body 301 from leaving the connecting channel 103, thereby making the connection between the heat exchanging units 101 more stable. Specifically, it may be arranged that the connection channel 103 is capable of blocking the first connection body 301 from moving in the depth direction of the connection channel 103, and for this purpose, the first connection body 301 and the connection channel 103 may be arranged such that: the first connecting body 301 protrudes in a direction away from the main body 102, and the width of the first connecting body 301 gradually increases along the protruding direction of the first connecting body 301; the connection passage 103 is recessed toward a direction near the center of the body 102, and the width of the connection passage 103 gradually increases in the direction in which the connection passage 103 is recessed. Referring to fig. 2 and 4, the cross sections of the first connecting body 301 and the connecting channel 103 are trapezoidal, the connecting channel 103 is concave downward, the first connecting body 301 is convex upward, the width of the connecting channel 103 gradually increases from top to bottom, and the width of the first connecting body 301 gradually increases from bottom to top. The width direction of the connection passage 103 or the first connection body 301 referred to herein corresponds to the left-right direction in fig. 2 or 4. Under the arrangement condition, when the first connecting body 301 tends to move upwards and separate from the connecting channel 103, the wall surface of the connecting channel 103 will abut against the first connecting body 301, so as to prevent the first connecting body 301 from separating from the connecting channel 103, and the arrangement mode is relatively simple in shape of the first connecting body 301 and the connecting channel 103, and is convenient for manufacturing and processing.

It should be noted that, on the basis that the wall surface of the connecting channel 103 can prevent the first connecting body 301 from separating from the connecting channel 103, the shape arrangement of the first connecting body 301 and the connecting channel 103 is not limited to the above arrangement, and the width of the first connecting body 301 or the connecting channel 103 is not limited to monotone increase along a specific direction. For example, as shown in fig. 14, the first connection body 301 and the connection passage 103 have a cross-section in a "T" shape; alternatively, as shown in fig. 15, the first connection body 301 and the connection passage 103 have a hexagonal cross section. In addition, the connecting channel 103 may also be configured as a long and narrow cavity, and is not limited to be configured as a slot, and other possible configurations are not limited to this.

In order to achieve connection and assembly between a larger number of heat exchange units 101, in some embodiments, heat exchange units 101 are provided with both first connection body 301 and connection channels 103. As shown in fig. 5 and 6, in some embodiments, the first connection body 301 and the connection channel 103 are disposed on two opposite wall surfaces of the main body 102, and a plurality of heat exchange units 101 shown in fig. 5 are sequentially connected to each other, so as to form a heat exchanger 1101 having a plate shape as a whole. As shown in fig. 7 and 8, in some embodiments, the first connection body 301 and the connection channel 103 are disposed on two adjacent wall surfaces of the main body 102; as shown in fig. 7, the upper side and the right side of the heat exchange unit 101 are respectively connected with one heat exchange unit 101, and the three heat exchange units 101 are connected to form an "L" shape, and a heat exchanger 1101 required to be bent can be assembled by using the heat exchange unit 101 shown in fig. 7, as shown in fig. 12 and 13 (the heat exchange unit 101 shown in fig. 7 is located at a corner in fig. 12). In the heat exchange unit 101 shown in fig. 1 to 8, the body 102 has a quadrangular prism shape, and the gap is small after the heat exchange unit 101 is connected.

The shape of the main body 102 and the relative positions of the first connecting body 301 and the connecting channel 103 on the same heat exchange unit 101 are not limited to the above arrangement. In other embodiments, the body 102 may be shaped as a triangular prism, a hexagonal prism, an octagonal prism, or a cylinder, among others; taking the shape of the main body 102 as a regular hexagonal prism as an example, the first connecting body 301 and the connecting channel 103 may be respectively disposed on two wall surfaces of the main body 102, wherein an included angle between the two wall surfaces is 60 degrees; the remaining possible arrangements are not different here.

As shown in fig. 5 to 8, two wall surfaces of the heat exchange unit 101 are respectively provided with the first connectors 301 and the connection channels 103, and for the heat exchange unit 101 with the prismatic shape of the main body 102, the first connectors 301 and the connection channels 103 can be optionally provided on a larger number of wall surfaces, so that a single heat exchange unit 101 can be connected with other heat exchange units 101 in multiple directions, which is beneficial to assembling a heat exchanger with a more complex shape. For example, the first connecting body 301 is provided on two wall surfaces of the body 102, and the connecting passage 103 is provided on the other two wall surfaces (the number of wall surfaces on which the first connecting body 301 is provided and the number of wall surfaces on which the connecting passage 103 is provided may be larger). In addition, the number of the wall surfaces of the body provided with the first connection body 301 and the number of the wall surfaces provided with the connection passage 103 may not be equal, and will not be exemplified in detail here.

Different heat exchange units 101 are selected for assembly to obtain different heat exchangers 1101, the shape and the size of the heat exchangers 1101 can be changed by increasing or decreasing the heat exchange units 101 or replacing part of the heat exchange units 101, so that the heat exchangers 1101 can be adapted to different shapes and sizes of targets to be heated, various different heat exchangers 1101 do not need to be designed and manufactured, and production and manufacturing costs are saved. In addition, the heat exchange units 101 are connected and disassembled in a mode that the first connecting body 301 enters and exits the connecting channel 103, and are fixed by abutting between the wall surface of the connecting channel 103 and the first connecting body 301, so that the assembly and fixing modes of the heat exchange units 101 are simple.

Referring to fig. 5 to 8, and fig. 17, in some embodiments, the body 102 is provided with a first end face 1601 and a second end face 1602, one end of the connection channel 103 is flush with the first end face 1601 or the second end face 1602, and one end of the first connector 301 is flush with the first end face 1601 or the second end face 1602. For example, in the heat exchange unit 101 shown in fig. 17, one end of the connecting channel 103 is flush with the first end surface 1061, and the other end of the connecting channel 103 extends toward the direction close to the second end surface 1602; this arrangement facilitates the movement of the first connecting body 301 into and out of the connecting passage 103.

On the basis of the above arrangement, the relative positions of the first connecting body 301 and the connecting channel 103 can be arranged in different manners. In one arrangement, as shown in fig. 16, the first connecting body 301 and the connecting channel 103 start from the same end face (the second end face 1602), and both extend in the same direction (towards the first end face 1601). After the heat exchange units 101 are connected as shown in fig. 16, if one (or more) heat exchange unit 101 located in the middle is to be taken out to adjust the size of the heat exchanger 1101, no matter the heat exchange unit 101 is taken out forward or the heat exchange unit 101 is taken out backward, the heat exchange unit 101 which needs to be taken out is always blocked by one adjacent heat exchange unit 101 and cannot be taken out smoothly (the rear side wall surfaces of the first connecting body 301 of one heat exchange unit 101 and the connecting channel 103 of the other heat exchange unit 101 abut against each other). The heat exchange unit 101 in the heat exchanger 1101 cannot be easily shifted or separated, and the structural stability of the heat exchanger 1101 is high.

In another arrangement, as shown in fig. 17, the first connecting body 301 and the connecting channel 103 respectively extend towards the other end surface of the main body 102 with the different end surfaces as starting points; if a certain heat exchange unit 101 in fig. 17 is to be taken out, the heat exchange units 101 may be extracted forward or backward (whether forward or backward depends on the placement direction of the target heat exchange unit 101), and the heat exchange units 101 do not need to be detached one by one from the heat exchange units 101 at the two ends in order to take out the middle heat exchange unit 101, so that the size and shape of the heat exchanger 1101 formed by the plurality of heat exchange units 101 are adjusted more flexibly and conveniently.

On the basis that the end of the first connecting body 301 and the end of the connecting channel 103 are flush with one end face of the main body 102, the lengths of the first connecting body 301 and the connecting channel 103 can be set to be equal, so that the heat exchanger 1101 formed by arranging and connecting the plurality of heat exchange units 101 in a specific manner has a regular overall shape and does not occupy too much storage space (as shown in fig. 16 and 17). The longitudinal direction here corresponds to the front/rear direction in fig. 16 or 17.

Referring to fig. 9 and 10, heat exchange needs to be performed through a heat exchange medium, and in order to facilitate introduction and extraction of the heat exchange medium into and out of the flow channel 901, in some embodiments, the heat exchange unit 101 further includes a second connection body 104, the second connection body 104 is connected to both ends of the main body 102, the second connection body 104 is disposed in a hollow manner, and an inner cavity of the second connection body 104 is communicated with the flow channel 901. The second connector 104 may be connected to a pipe for providing or collecting a heat exchange medium, the pipe for the heat exchange medium may be sleeved on an outer edge of the second connector 104, and the pipe may be a pipe made of metal such as a copper pipe, or may be a rubber pipe (made of rubber or plastic). In order to increase the connection reliability with the rubber or plastic pipe, in some embodiments, the second connection body 104 includes a pipe fastening portion 1001, and the pipe fastening portion 1001 protrudes in a direction away from the center of the second connection body 104. Specifically, the second connection body 104 has a substantially cylindrical shape, and the pipe fastening portion 1001 projects in a direction away from the axis of the second connection body 104. Due to the arrangement of the pipe fastening portion 1001, the rubber pipe sleeved on the periphery of the second connecting body 104 can deform to a larger extent, and due to the tendency of resetting of the rubber pipe, the inner wall surface of the rubber pipe can apply a larger pressure to the second connecting body 104, so that the friction between the rubber pipe and the second connecting body 104 is increased, and the tightness and the connection reliability between the heat exchange medium pipe and the second connecting body 104 are improved.

The invention also provides a heat exchanger 1101 which comprises the heat exchange unit 101 in the embodiment, the heat exchanger 1101 is simple to assemble, high in connection reliability, easy to adjust the shape and size of the whole body, and low in design and manufacturing cost.

Referring to fig. 11-13, a specific embodiment of two heat exchangers 1101 is shown. The heat exchanger 1101 shown in fig. 11 is plate-shaped and includes a plurality of heat exchange units 101 shown in fig. 5, and the heat exchange units 101 at two ends of the heat exchanger 1101 are the heat exchange unit 101 shown in fig. 1 and the heat exchange unit 101 shown in fig. 3. Heat exchanger 1101 shown in fig. 12 and 13 is of the "C" type wherein heat exchange unit 101 is selected and assembled in a manner similar to that of fig. 11, except that the corner of heat exchanger 1101 is selected to be heat exchange unit 101 as shown in fig. 7.

In addition, regarding the flow path design of the heat exchange medium in the heat exchanger 1101, as shown in fig. 18, each heat exchange unit 101 has an inlet pipe 1801 and an outlet pipe 1802 connected thereto; as shown in fig. 19, the flow passages 901 of the adjacent heat exchange units 101 may be connected by a plurality of U-shaped pipes 1803, and then the inflow pipe 1801 and the outflow pipe 1802 of the heat exchange medium may be connected to the heat exchange units 101 at both ends of the heat exchanger 1101. Wherein the heat exchange medium flows into heat exchange unit 101 through inflow tube 1801 and flows out of heat exchange unit 101 through outflow tube 1802.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
