[0046] In order to enable those skilled in the art to better understand the present utility model and thus more clearly define the scope of protection required by the present utility model, the present utility model will be described in detail below with respect to certain specific embodiments of the present utility model. It should be noted that the following are only some specific implementation manners of the concept of the present utility model and only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present utility model, and each specific feature does not of course and directly limit the scope of implementation of the present utility model. Conventional selections and substitutions made by those skilled in the art under the guidance of the concept of the present utility model shall be regarded as within the scope of protection required by the present utility model.

[0047] Embodiment 1:

[0048] As Figures 1 - 5 shown, the present utility model discloses a temperature-sensing sensor card that is convenient for installation, including a card seat 1. An installation area 2 is provided on the front side of the card seat 1, and an installation part 3 is provided on the rear side, so that the temperature-sensing sensor 4 can be installed on the installation area 2 and installed on the heat exchanger 7 through the installation part 3 to realize the installation of the temperature-sensing sensor 4 relative to the heat exchanger 7, thereby detecting the temperature around the heat exchanger 7 through the temperature-sensing sensor 4.

[0049] Specifically, the installation part 3 includes a first clamping member 31 and a second clamping member 32; the first clamping member 31 is in an L shape or a hook shape, so that a hook groove 313 with a forward single-side opening or forward and downward two-side openings is formed on the first clamping member 31. The first clamping member 31 is hooked on the heat exchanger 7 through the hook groove 313, so that the card seat 1 rotates relative to the heat exchanger 7; and the second clamping member 32 is provided with an arc-shaped buckling groove 321, and the second clamping member 32 first abuts against the heat exchanger 7 during the rotation of the card seat 1, and then continues to rotate so that the heat exchanger 7 passes over the second clamping member 32 and is buckled into the buckling groove 321.

[0050] Therefore, during the process of installing the temperature sensor card on the heat exchanger 7, first, it is easily hooked on the heat exchanger 7 through the hook groove 313 on the first clamping member 31. Then, under the cooperation of the first clamping member 31 and the heat exchanger 7, the card holder 1 is rotated, so that the card holder 1 rotates to make the second clamping member 32 approach and abut against the heat exchanger 7. After that, a force is applied to make the card holder 1 continue to flip. During the flipping process, the second clamping member 32 deforms to enable the heat exchanger 7 to cross over the second clamping member 32 and enter the buckle groove 321. The flipping limit of the card holder 1 is achieved through the snap-fit between the buckle groove 321 and the heat exchanger 7. During the overall installation process, only a certain force needs to be applied when the heat exchanger 7 crosses over the second clamping member 32, making the installation more labor-saving. Moreover, the force applied during this process is also guided under the rotational cooperation of the first clamping member 31 and the heat exchange member, and it is impossible to align the second clamping member 32 and the heat exchanger 7, making the assembly smoother.

[0051] In addition, a positioning surface 11 is provided at the rear side of the card holder 1 in this embodiment. The positioning surface 11 is used to abut against the heat exchanger 7 when the heat exchanger 7 is snapped into the buckle groove 321. Therefore, the stable installation of the temperature sensor card on the heat exchanger 7 is achieved respectively through the hook connection between the first clamping member 31 and the heat exchanger 7, the snap connection between the second clamping member 32 and the heat exchanger 7, and the abutment between the positioning surface 11 and the heat exchanger 7.

[0052] Preferably, the distance from the rotation axis k under the cooperation of the first clamping member 31 and the heat exchanger 7 to the positioning surface 11 in this embodiment is s1, and the distance from the rotation axis k under the cooperation of the first clamping member 31 and the heat exchanger 7 to the plane M where the positioning surface 11 is located is s2, and s1 > s2.

[0053] Therefore, as Figure 4 shown, when the card holder 1 is in an inclined state, the first clamping member 31 is hooked on the heat exchanger 7. At this time, the positioning surface 11 and the heat exchanger 7 are in a non-disengaged state, and the second clamping member 32 and the heat exchanger 7 are in a non-snapped state. After that, the card holder 1 rotates from the Figure 4 shown state to the Figure 5 shown state to achieve the abutment between the positioning surface 11 and the heat exchanger 7 and the snap connection between the second clamping member 32 and the heat exchanger.

[0054] Among them, the inner peripheral wall of the hook groove 311 is an arc surface, and the arc center axis of the hook groove 311 is the rotation axis k under the cooperation of the first clamping member 31 and the heat exchanger 7.

[0055] Specifically, the first clamping member 31 in this embodiment is L-shaped and is located at the lower rear side of the card holder 1. Among them, the first clamping member 31 includes an extension section 311 and a hook portion 312. One end of the extension section 311 is integrally formed and connected to the card holder 1, and the other end extends backward. One end of the hook portion 312 is integrally formed and connected to the rear end of the extension section 311, and the other end extends downward. Thus, the rotation axis k formed by the cooperation of the first clamping member 31 and the heat exchanger 7 is located below the extension section 311 and in front of the hook portion 312, that is, the rotation axis k formed by the cooperation of the first clamping member 31 and the heat exchanger 7 is located at the lower rear side of the positioning surface 11, so as to ensure s1>s2. In addition, after the installation is completed, any force acting backward on the front side of the card holder 1 cannot generate a component force that causes the second clamping member 32 to move in the direction of disengaging from the heat exchanger 7, so that the installation of the card holder 1 is more stable.

[0056] Specifically, the second clamping member 32 in this embodiment is located at the vertical middle position of the card holder 1, and one side of the second clamping member 32 is integrally formed on the card holder 1, and the other side extends backward. Among them, a buckle groove 321 is opened at the upper rear side of the second clamping member 32, and the buckle groove 321 is arranged in an arc shape with an arc less than Π. In addition, the arc opening of the buckle groove 321 is arranged upward and backward, and the included angle between the orientation of the arc opening of the buckle groove 321 and the front-rear direction is α, and α is about 60°.

[0057] Therefore, during the process of the heat exchanger 7 being clamped into the second clamping member 32, the heat exchanger 7 and the second clamping member 32 are only released from force at a single position, so that it is more convenient and labor-saving for the heat exchanger 7 to cross over the second clamping member 32.

[0058] Preferably, a deformation area 12 is provided between the first clamping member 31 and the second clamping member 32 in this embodiment, so that the deformation area 12 provides a deformation space for the second clamping member 32 during the process of the heat exchanger 7 crossing over the second clamping member 32, so that the second clamping member 32 deforms more smoothly to complete the assembly.

[0059] Preferably, the number of the first clamping members 31 and the second clamping members 32 in this embodiment is two each, and they are arranged on the left and right sides of the card holder 1, so as to improve the installation stability of the temperature sensor card under the action of multiple groups of the first clamping members 31 and the second clamping members 32.

[0060] In addition, a first wire routing area 21 with a left-right direction and a second wire routing area 22 with an up-down direction are provided in the installation area 2 of this embodiment, and the right side of the first wire routing area 21 intersects with the upper side of the second wire routing area 22. In addition, a wire winding post 23 is provided at the intersection of the first wire routing area 21 and the second wire routing area 22 in the installation area 2. Therefore, the wire parts of the temperature sensors 4 to be installed on the temperature sensor card are respectively clamped in the first wire routing area 21 and the second wire routing area 22, and are bent orderly through the wire winding post 23 to change the direction.

[0061] Among them, a first wire blocking rib 211 is integrally formed on the upper side wall of the first wire routing area 21. The first wire blocking rib 211 extends downward and tilts forward at the same time, and a first opening 212 is provided between the lower side of the first wire blocking rib 211 and the lower side of the first wire routing area 21.

[0062] Therefore, the wire part of the temperature sensor 4 that needs to be placed in the first wire routing area 21 enters the first wire routing area 21 through the first opening 212, and is stably placed in the first wire routing area 21 under the restriction of the upper and lower side walls of the first wire routing area 21 and the first wire blocking rib 211, and can be conveniently disassembled and assembled.

[0063] Among them, a second wire blocking rib 231 is integrally formed on the front side of the wire winding column 23; so that the wire part wound around the wire winding column 23 is restricted forward by the second wire blocking rib 231 to ensure the stability of wire winding.

[0064] Among them, the second wire routing area 22 includes a wire body area 221 and a head area 222. The wire body area 221 intersects with the first wire routing area 21 above, and the head area 222 is below. So that the wire part of the temperature sensor 4 that needs to be placed in the second wire routing area 22 is located in the wire body area 221, and the sensor head 43 of the temperature sensor 4 is placed in the head area 222.

[0065] Among them, a first positioning rib 2211 extending leftward is provided on the right side wall of the wire body area 221, so that a first positioning groove 2212 is formed between the first positioning rib 2211 and the left side wall of the wire body area 221. Therefore, under the action of the first positioning groove 2212, the wire part located in the wire body area 221 is bundled, making the installation more stable.

[0066] Among them, a second positioning rib 2221 is integrally formed in the middle of the left and right sides of the head area 222. A second positioning groove 2222 is formed between the second positioning rib 2221 and the left side wall of the head area 222, so that the sensor head 43 of the temperature sensor 4 is placed in the second positioning groove 2222 and is more stable.

[0067] Among them, a third positioning rib 2223 is integrally formed on the left side wall of the head area 222. The third positioning rib 2223 includes an extending body 22231 extending rightward and an inclined body 22232 extending rightward and forward. A second opening 2224 is provided between the inclined body 22232 and the other side wall in the width direction of the head area 222. Therefore, the sensor head 43 of the temperature sensor 4 is placed into the head area 222 through the second opening 2224, and the inclined body 22232 more smoothly guides the sensor head 43 of the temperature sensor 4 into the extending body 22231, and under the action of the extending body 22231, the front and back movement of the sensor head 43 of the temperature sensor 4 is restricted to ensure the stability of installation.

[0068] Embodiment 2:

[0069] A temperature-sensing sensor card that is easy to install has the same main structure as that of the first embodiment. The difference is that the first clamping member 31 is hook-shaped, so that the hook-shaped first clamping member 31 has the ability to hook the heat exchanger 7, and the rotation of the first clamping member 31 and the heat exchanger 7 in the hooked state is more stable, and the problem of the first clamping member 31 and the heat exchanger 7 becoming unhooked will not occur.

[0070] Embodiment Three:

[0071] As Figures 6 - 9 shown, the present utility model discloses a heat exchanger, which includes a plurality of heat exchange tubes 5, a plurality of fins 6, and the temperature-sensing sensor card that is easy to install described in the first embodiment or the second embodiment, and a temperature-sensing sensor 4.

[0072] Specifically, the heat exchange tubes 5 are arranged in a matrix, and the length direction of the heat exchange tubes 5 is along the left-right direction. The fins 6 are arranged along the length direction of the heat exchange tubes 5, and through holes are formed in each fin 6 for the heat exchange tubes 5 to pass through, so as to realize the connection between the fins 6 and the heat exchange tubes 5.

[0073] Therefore, the gas-liquid flowing in the heat exchange tubes 5 heats up or cools down the fins 6 through heat conduction, and the fins 6 are in large-area contact with the outside to quickly exchange heat.

[0074] Specifically, the temperature-sensing sensor 4 includes a first wire 41 bent in an L shape and a second wire 42. A PVC sheath 44 is sleeved on the outer periphery of the first wire 41 to play a protective role, and a sensor head 43 is arranged at the lower end of the second wire 42.

[0075] Therefore, the PVC sheath 44 together with the first wire 41 enters the first wire routing area 21 from the first opening 212, the second wire 42 enters the wire body area 221, and a part of the structure of the second wire 42 is stuck in the first positioning groove 2212 and is subjected to the effect of receiving and positioning. In addition, the sensor head 43 enters the head area 222 through the second opening 2224, and then enters below the extension body 22231 along the inclined body 22232. Under the action of the extension body 22231, the sensor head 43 is stably restricted in the head area 222. In addition, the sensor head 43 entering the head area 222 further enters the second positioning groove 2222, and the installation stability is improved under the clamping action of the second positioning groove 2222. In addition, the first wire 41 and the second wire 42 turn at the wire winding post 23, and are prevented from coming out of the wire winding post 23 under the action of the second wire blocking rib 231.

[0076] Among them, a sleeve member 61 is respectively arranged corresponding to each heat exchange tube 5 on the right side of each fin 6. The sleeve member 61 is in the shape of a cylinder extending to the right, so that the sleeve member 61 is sleeved on the heat exchange tube 5 to improve the installation stability of the fin 6, making the fin 6 not prone to lodging. In addition, the sleeve member 61 includes a first mounting member 611 and a second mounting member 612. The first clamping member 31 is hooked on the outer periphery of the first mounting member 611, the second clamping member 32 is buckled on the outer periphery of the second mounting member 612, and the positioning surface 11 abuts against the front side of the fin 6.

[0077] Therefore, the first clamping member 31, the second clamping member 32, and the positioning surface 11 all act on the fin 6, making the force on the fin 6 more stable, so that the fin 6 is not prone to lodging during the installation process. Moreover, the first mounting member 611 and the second mounting member 612 are sleeved on the heat exchange tube 5, so that the first positioning member and the second positioning member are more stable due to the support of the heat exchange tube 5.

[0078] Embodiment 4:

[0079] A heat exchanger, whose main structure is the same as that of Embodiment 3, except that the sleeve member 61 is not arranged on the fin 6. A first mounting member 611 and a second mounting member 612 in the shape of a cylinder or a cylinder are arranged on the right side of each fin 6, and the first mounting member 611 and the second mounting member 612 do not need to be sleeved on the outer periphery of the heat exchange tube 5.

[0080] Embodiment 5:

[0081] As Figure 10 shown, a heat exchanger, whose main structure is the same as that of Embodiment 3, except that the first mounting member 611 and the second mounting member 612 are not arranged on the fin 6. Instead, the heat exchange tube 5 includes a first tube body 51 and a second tube body 52. The first clamping member 31 is hooked on the outer periphery of the first tube body 51, and the second clamping member 32 is buckled on the outer periphery of the second tube body 52.
