In the second embodiment of the vent hole 12, the energy storage cavity 11 semi-surrounds the vent hole 12, so that the vent hole 12 has a lateral gap, which is favorable for distributing the liquid level of the energy carrying agent 200 in the energy storage cavity 11 and the liquid level of the energy carrying agent 200 in the second heat exchanger 30 at the same level, so as to be favorable for the circulation of the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30, and thus, the rapid heat exchange between the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30 can be realized; and facilitates the installation of the second heat exchanger 30. Note that the side opening refers to an opening located on one side of the center line of the vent hole 12, and the side direction may refer to a direction away from the center line of the vent hole 12.
In the second embodiment of the vent hole 12, specifically, the hole wall of the vent hole 12 may be used to form a duct wall of a heat exchange duct.
In the second embodiment of the vent hole 12, specifically, the second heat exchanger 30 is disposed in the vent hole 12, so that at least the second heat exchanger 30 can be installed conveniently, and the energy carrier 200 in the energy storage cavity 11 can be distributed around the second heat exchanger 30 in a semi-surrounding manner. When the heat exchanger is used, the lateral notches of the vent holes 12 can be arranged towards the left or the right, so that the liquid level of the energy carrying agent 200 in the energy storage cavity 11 is equal to the liquid level of the energy carrying agent 200 in the second heat exchanger 30, part of the liquid level is higher than the liquid level of the energy carrying agent 200 in the second heat exchanger 30, and part of the liquid level is lower than the liquid level of the energy carrying agent 200 in the second heat exchanger 30, thereby being beneficial to the circulation of the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30, and realizing the rapid heat exchange between the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30.
Of course, in a modified embodiment of the second embodiment of the vent 12, the second heat exchanger 30 may be partially disposed in the vent 12 and partially disposed (i.e., extended) in the energy storage cavity 11, so as to increase the heat exchange speed between the energy carrier 200 in the energy storage cavity 11 and the energy carrier 200 in the second heat exchanger 30, and improve the cooling/heating effect of the mobile air conditioner 100.
Of course, in another variant of the second embodiment of the vent 12, the second heat exchanger 30 may also be partially disposed in the vent 12, and partially protrude laterally beyond the lateral opening of the vent 12.
Of course, in other embodiments of the present invention, the second heat exchanger 30 may also be directly disposed on one side of the energy storage shell 10 without disposing the vent 12, for example, the second heat exchanger 30 and the energy storage shell 10 may be disposed side by side in the horizontal direction, so that the liquid level of the energy carrying agent 200 in the energy storage cavity 11 and the liquid level of the energy carrying agent 200 in the second heat exchanger 30 may be distributed on the same level, which is favorable for the circulation of the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30, and thus, the rapid heat exchange between the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30 may be realized; for another example, the second heat exchanger 30 may be disposed below the energy storage shell 10, so that the liquid level of the energy carrying agent 200 in the energy storage cavity 11 may be higher than the liquid level of the energy carrying agent 200 in the second heat exchanger 30, which may facilitate the circulation of the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30, and thus may achieve rapid heat exchange between the energy carrying agent 200 in the energy storage cavity 11 and the energy carrying agent 200 in the second heat exchanger 30. At this time, the second heat exchanger 30 may be disposed in the heat exchange air duct.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The following mainly describes the arrangement of the first heat exchanger 20 in detail.
In the first embodiment of the first heat exchanger 20, as shown in fig. 1 to 3, the first heat exchanger 20 is disposed in the energy storage chamber 11, that is, the first heat exchanger 20 is disposed in the energy storage chamber 11 in its entirety. Thus, the first heat exchanger 20 can be arranged in the energy carrier 200 in the energy storage cavity 11, and the structure of the heat exchange assembly 1 can be simplified.
In the second embodiment of the first heat exchanger 20, the first heat exchanger 20 comprises a first heat exchanging part 21 and a second heat exchanging part 22 which are connected with each other, the first heat exchanging part 21 is arranged in the energy storage shell 10, and the heat exchanging pipes of the second heat exchanging part 22 and the heat exchanging pipes of the second heat exchanger 30 are at least partially arranged alternately at intervals. Thus, during energy storage, the first heat exchanging part 21 can exchange heat with the energy carrier 200 in the energy storage shell 10 to store energy in the energy carrier 200 in the energy storage shell 10; because the heat exchange tubes of the second heat exchange part 22 and the heat exchange tubes of the second heat exchanger 30 are at least partially alternately arranged at intervals, the second heat exchange part 22 can directly exchange heat with the second heat exchanger 30 to directly store energy in the energy carrier 200 in the second heat exchanger 30; that is, the first heat exchanger 20 can directly store energy not only for the energy carrier 200 in the energy storage shell 10, but also for the energy carrier 200 in the second heat exchanger 30; therefore, the energy storage speed can be effectively improved, the time required by energy storage is reduced, and the use comfort is improved.
It should be noted that, during energy releasing, since the heat exchange tubes of the second heat exchange portion 22 and the heat exchange tubes of the second heat exchanger 30 are at least partially alternately arranged at intervals, when air passes through the second heat exchanger 30, the air also passes through the second heat exchange portion 22, so that the second heat exchange portion 22 also exchanges heat with the air to change the temperature of the air. In particular, when the energy in the energy carrier 200 is low, i.e., when the second heat exchanger 30 cannot effectively change the temperature of the air, the second heat exchanging part 22 may sufficiently exchange heat with the air to effectively change the temperature of the air, so that the use flexibility of the mobile air conditioner 100 may be improved.
In the second embodiment of the first heat exchanger 20, specifically, there are various forms of the "heat exchange tubes of the second heat exchange portion 22 and the heat exchange tubes of the second heat exchanger 30 are at least partially alternately arranged" as illustrated below.
In the first embodiment of the second heat exchanging part 22, as shown in fig. 4, the second heat exchanging part 22 includes at least one layer of the first heat exchanging tubes 221a, and the second heat exchanger 30 includes a plurality of layers of the second heat exchanging tubes 331 a. Specifically, when the number of the first heat exchange tubes 221a is set to one layer, the layer of the first heat exchange tubes 221a is disposed between any two adjacent layers of the second heat exchange tubes 331a, or the layer of the first heat exchange tubes 221a is disposed on the outer side surface of the outermost second heat exchange tube 331 a. When the number of the first heat exchange tubes 221a is set to be multiple layers (greater than or equal to two layers), at least one layer of the second heat exchange tube 331a is disposed between any two adjacent layers of the first heat exchange tubes 221 a.
In the first embodiment of the second heat exchanging part 22, it can be understood that after the energy storage process is completed, the energy storage system is normally closed, that is, the first heat exchanger 20 is in an idle state, so that the second heat exchanging part 22 cannot change the temperature of the air, and the wind resistance is increased. Based on this, optionally, the number of the first heat exchange tubes 221a is set to be multiple, and two, three or four layers of second heat exchange tubes 331a are arranged between any two adjacent layers of the first heat exchange tubes 221 a; in this way, the capability of changing the air temperature of the second heat exchanging part 22 during energy releasing can be reserved, and the wind resistance can be reduced.
In the first embodiment of the second heat exchanging part 22, specifically, as shown in fig. 4, any two adjacent layers of the first heat exchanging pipes 221a are communicated with each other.
In the second embodiment of the second heat exchanging part 22, as shown in fig. 4, the second heat exchanging part 22 includes a plurality of third heat exchanging pipes 221b, the second heat exchanger 30 includes a plurality of fourth heat exchanging pipes 331b, and at least one of the third heat exchanging pipes 221b and at least one of the fourth heat exchanging pipes 331b are located in the same layer of heat exchanging pipes.
In the second embodiment of the second heat exchanging part 22, specifically, as shown in fig. 5, at least one fourth heat exchanging tube 331b is arranged between any two adjacent third heat exchanging tubes 221b in the same layer of heat exchanging tubes.
For substantially the same reason as in the first embodiment of the second heat exchanging portion 22, optionally, two, three, or four fourth heat exchanging tubes 331b are provided between any adjacent two third heat exchanging tubes 221b in the same layer of heat exchanging tubes.
In the second embodiment of the second heat exchanging part 22, specifically, as shown in fig. 5, the heat exchanging pipes of the second heat exchanging part 22 and the heat exchanging pipes of the second heat exchanger 30 form a plurality of layers of heat exchanging pipes, wherein the third heat exchanging pipe 221b in one layer of heat exchanging pipes is arranged in a staggered manner with the third heat exchanging pipe 221b in the adjacent layer of heat exchanging pipes. Optionally, the third heat exchange tube 221b in any layer of heat exchange tubes is staggered with the third heat exchange tube 221b in the adjacent layer of heat exchange tubes. In this way, the heat exchange efficiency between the second heat exchange portion 22 and the second heat exchanger 30 can be improved.
In the second embodiment of the second heat exchanging part 22, specifically, as shown in fig. 5, any two adjacent third heat exchanging pipes 221b communicate with each other in the same layer of heat exchanging pipes. In two adjacent layers of heat exchange tubes, two third heat exchange tubes 221b located on the same side are communicated with each other.
It should be noted that the above technical solutions between the embodiments of the first heat exchanger 20 and the second heat exchanger 30 can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
Further, as shown in fig. 1-3, the second heat exchanger 30 may alternatively be a finned heat exchanger. Thus, the heat exchange area can be increased. Specifically, the second heat exchanger 30 includes a heat exchange tube 33 and a fin 34 disposed outside the heat exchange tube, and the heat exchange tube may be a copper tube.
It should be noted that, in a specific embodiment, the second heat exchanger 30 and the energy carrier 200 in the energy storage cavity 11 may be exchanged through a liquid level difference, a temperature change, and the like, or may be exchanged through a power system. In the present embodiment, the second heat exchanger 30 exchanges with the energy carrier 200 in the energy storage cavity 11 through a liquid level difference, a temperature change, and the like.
Further, the inner wall surface of the energy storage cavity 11 is provided with a first thermal insulation layer (not shown); and/or the outer surface of the energy storage shell 10 is provided with a second heat insulation layer (not shown). Thus, the thermal insulation performance of the energy storage chamber 11 can be improved, energy leakage and loss can be reduced or even avoided, and energy consumption can be reduced.
In another embodiment of the heat exchange assembly 1 of the present invention, as shown in fig. 3, the second heat exchanger 30 exchanges with the energy carrier 200 in the energy storage cavity 11 through a power system; specifically, in this embodiment, the heat exchange assembly 1 further includes a power system, and the power system is configured to drive the energy carrier 200 in the energy storage cavity 11 to circulate between the second heat exchanger 30 and the energy storage cavity 11, so as to improve a heat exchange effect between the first heat exchanger 20 and the energy carrier 200, and also improve a heat exchange effect between the second heat exchanger 30 and air. In this embodiment, as shown in fig. 3, the power system optionally comprises a water pump 60, and the water pump 60 is arranged in the energy release flow path between the second heat exchanger 30 and the energy storage shell, that is, the water pump 60 is arranged at the energy carrier outlet 32 or the energy carrier inlet 31 of the second heat exchanger 30 to drive the energy carrier 200 to circulate between the second heat exchanger 30 and the energy storage cavity 11 (it is understood that when a plurality of energy carrier outlets 32 and a plurality of energy carrier inlets 31 are provided, the water pump 60 may be arranged at one of the energy carrier outlets 32 or one of the energy carrier inlets 31).
