Detailed Description
In the present application, the terms of orientation such as "thickness direction" and "horizontal direction" are used for clarity of the technical solution of the present application, and are not intended to limit the scope of the present application.
The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 and 2, the present application provides an electric heating apparatus of an electric vehicle, the electric heating apparatus including: a heat exchange assembly 10, the heat exchange assembly 10 being provided with a cavity therein for receiving and heating a fluid medium; the first shell 20 is mounted on the first periphery 11 of the heat exchange assembly 10 in an adhering mode through a sealant, and an electrical cavity 21 provided with the control circuit board 16 is formed between the first shell 20 and the heat exchange assembly 10; and a second housing 30, the second housing 30 being adhesively attached to the second peripheral edge 12 of the heat exchange assembly 10 by a sealant and forming with the heat exchange assembly 10 a heating cavity 31 containing the electrical resistance heating element 14.
The heat exchange assembly 10 is communicated with a flow path in a heat dissipation system of the electric vehicle, when a fluid medium in the flow path passes through the interior of the heat exchange assembly 10, the fluid medium is heated by an electric heating device to raise the temperature of the fluid medium, and in order to fully heat the fluid medium, a flow path can be arranged in a cavity of the heat exchange assembly 10 to increase the stroke of the fluid medium in the heat exchange assembly 10. In order to increase the integration of the electric heating apparatus, it is generally preferable that the resistance heating element 14 and the control circuit board 16 are both disposed in the electric heating apparatus and are disposed separately, so as to avoid the over-temperature of the control circuit board 16 caused by the heat generation of the resistance heating element 14. Wherein the control circuit board 16 is disposed in an electrical cavity 21 formed between the first housing 20 and the heat exchange assembly 10 and the resistive heating element 14 is disposed in a heating cavity 31 formed between the second housing 30 and the heat exchange assembly 10. To protect the control circuit board 16 and the resistive heating element 14 from external influences, the electrical cavity 21 and the heating cavity 31 are preferably arranged to have a high gas tightness or complete sealing, but preferably with a controlled venting design, as will be described in detail below.
According to the electric heating device of the present application, the first casing 20 and/or the second casing 30 are adhesively mounted on both sides of the heat exchange assembly 10 by using a sealant, on one hand, for fixing connection and on the other hand, improving sealing performance. In the traditional scheme, if the shell and the heat exchange assembly are connected through the adhesive of the sealant, the adhesive thickness of the sealant is difficult to ensure, so that the situation of uneven distribution of the sealant can occur, and the sealing effect between the shell and the heat exchange assembly is poor; the use of fasteners in combination with seals to achieve a sealed connection between the housing and the heat exchange assembly can increase production costs.
In the technical solution of the present application, a structural design capable of uniformly distributing the sealant is provided between the first casing 20 and the second casing 30 of the electric heating apparatus and the heat exchange assembly 10, so that the distance of the sealant in the thickness direction of the electric heating apparatus is uniformly distributed in a space which is substantially consistent, and the sealing performance of the electric cavity 21 and the heating cavity 31 can be better ensured.
Specifically, as shown in fig. 3, a first glue joint space 40 for accommodating the sealant is formed between the first casing 20 and the first periphery 11, and the distance of the first glue joint space 40 in the thickness direction of the electric heating apparatus is substantially uniform; and/or a second gluing space for containing the sealant is formed between the second shell 30 and the second periphery 12, and the distance of the second gluing space in the thickness direction of the electric heating device is basically consistent. The second gluing space is not shown in the figures, and it can be understood that the second gluing space can be arranged in the same or similar scheme as the first gluing space 40, or in different arrangements according to the needs of the working conditions, for example, only one of the first gluing space 40 and the second gluing space can be arranged to have a substantially uniform distance in the thickness direction of the electric heating apparatus. The first glue joint space 40 and/or the second glue joint space preferably include glue accommodating spaces 41 arranged in the thickness direction of the electric heating device, and since the space distances of the glue accommodating spaces 41 in the thickness direction are substantially consistent, when the glue accommodating spaces 41 are filled with the sealant, the sealant can be distributed relatively uniformly in the glue accommodating spaces 41.
According to the scheme, the thickness distribution of the sealant in the glue containing space 41 in the thickness direction is uniform, so that the sealing performance of the sealant on the electric cavity and/or the heating cavity can be improved, external water, water vapor dust and the like can be effectively prevented from entering the electric heating equipment, and the safety and the reliability of the electric heating equipment in working are improved.
In the cross section shown in fig. 3, the first casing 20 and/or the second casing 30 may be defined by fasteners such as bolts or snaps, or may be defined by other non-fixedly installed limiting mechanisms. The first glue joint space and/or the second glue joint space may have other space parts than the thickness direction, such as a space in a horizontal direction or a space in an inclined direction.
Preferably, as shown in fig. 3 and 4, a spacer 22 extending in the thickness direction is provided in the glue containing space 41. The spacer 22 is supported in the first gluing space 40 and/or the second gluing space to achieve a substantially uniform distance of the first gluing space 40 and/or the second gluing space in the thickness direction of the electric heating apparatus. The number of the spacers 22 may be plural, and a plurality of the spacers 22 are preferably uniformly distributed in the first glue joint space 40 and/or the second glue joint space, or one spacer 22 may be provided, and the one spacer 22 is an elongated structure extending in a direction perpendicular to the cross section shown in fig. 3. The spacer 22 may be a separate piece or, preferably, as shown in fig. 3, the spacer 22 extends from the first and/or second housings 20, 30 toward the heat exchange assembly 10; or as shown in fig. 5-7, the partitions 22 extend from the heat exchange assembly 10 toward the first and/or second housings 20, 30. The partition 22 may be located in the middle of the glue containing space 41 as shown in fig. 3, so as to increase the bonding area between the shell and the heat exchange assembly 10 and increase the bonding strength; alternatively, the partition 22 may be located on one side of the glue containing space 41 as shown in fig. 5-7, so that the excess sealant only overflows toward the other side of the glue containing space 41, such as only overflowing into the heating cavity 31 or the electrical cavity 21 to keep the exterior appearance of the electrical heating apparatus beautiful, or only overflowing to the exterior of the electrical heating apparatus to prevent the sealant from overflowing onto the control circuit board 16 or the resistance heating element 14.
In the process of bonding, the total amount of the sealant is preferably higher than the capacity of the sealant containing space 41, so that the sealant applied in advance is pressed while the first shell 20 or the second shell 30 is close to the heat exchange assembly 10, and the sealant is fully filled in the sealant containing space 41, thereby achieving a high sealing effect. Meanwhile, the excess sealant overflows the sealant containing space 41. Preferably, as shown in fig. 3 and 4, the first shell 20 and/or the second shell 30 is provided with a skirt portion 13 extending in the thickness direction and located outside the heat exchange assembly 10, and a flash space 42 is formed between the skirt portion 13 and the outside of the heat exchange assembly 10.
According to this embodiment, the sealant overflowing the sealant accommodating space 41 can overflow into the sealant overflowing space 42 under the limitation of the skirt portion 13, so that the bonding area between the first shell 20 and/or the second shell 30 and the first peripheral edge 11 and/or the second peripheral edge 12 of the heat exchange assembly 10 is increased, and the bonding strength and the sealing performance are improved. In the cross section shown in fig. 3 and 4, the included angle between the glue overflow space 42 and the glue containing space 41 may be an obtuse angle or a right angle, or preferably, the connecting position between the glue overflow space 42 and the glue containing space 41 is an arc transition, so that the sealant easily overflows into the glue overflow space 42. The space distance of the glue containing space 41 in the thickness direction is preferably greater than or equal to the space distance of the glue overflowing space 42 in the horizontal direction, so that the sealant can be fully filled in the glue containing space 41 as much as possible according to the characteristic of strong adsorbability of the colloid fluid, and the sealant in the glue overflowing space 42 can be prevented from running off before being dried.
According to the above embodiment, the inner peripheral dimensions of the skirt portions 13 of the first and second housings 20 and 30 of the electric heating apparatus are larger than the outer peripheral dimensions of the first and second peripheries 11 and 12 of the heat exchange assembly 10, respectively. In order to maintain the glue overflowing space 42 at a uniform spatial distance at each position, a limiting structure 131 is preferably arranged in the glue overflowing space 42, as shown in fig. 8, and the limiting structure 131 is used for limiting the spatial distance between the skirt portion 13 and the heat exchange assembly 10 in the horizontal direction. The limiting structure 131 in the flash space 42 may be a protrusion disposed on the inner side of the skirt portion 13 or on the outer side of the first peripheral edge 11 and/or the second peripheral edge 12, or preferably, as shown in fig. 1 and 8, the limiting structure 131 is a concave structure formed by bending the skirt portion 13 toward the inner side and capable of abutting against the outer side of the first peripheral edge 11 and/or the second peripheral edge 12.
As shown in fig. 5 to 7, according to another preferred embodiment of the present application, one of the first casing 20 and the first periphery 11 of the electric heating apparatus may further include a first protrusion 23, and the other includes a first recess 24 opposite to the first protrusion and accommodating the first protrusion 23, and a glue accommodating space 41 is formed between the first protrusion 23 and the first recess 24; and/or one of the second shell 30 and the second periphery 12 comprises a second projection and the other comprises a second recess opposite to and accommodating the second projection, a glue-accommodating space 41 being formed between the second projection and the second recess.
In this embodiment, the glue containing space 41 includes not only the space between the first shell 20 and/or the second shell 30 and the heat exchange assembly 10 in the thickness direction, but also the space between the first protrusion 23 and the first recess 24 and between the second protrusion and the second recess in the thickness direction, thereby further increasing the bonding area and improving the bonding strength. In the bonding operation, it is preferable that the sealant is first filled into the first recess 24 or the second recess, and then the first shell 20 or the second shell 30 is fitted to the heat exchange assembly 10, and the first protrusion 23 or the second protrusion presses the excess sealant toward the flash space 42.
In the above embodiments, the first protrusion 23 and the second protrusion may have various expressions according to actual conditions. Here, as shown in fig. 5, the first protruding portion 23 may be a bent structure in which the first casing 20 is recessed toward the first peripheral edge 11 in the thickness direction, or as shown in fig. 6, the first protruding portion 23 is a skirt structure in which the peripheral edge of the first casing 20 extends toward the first peripheral edge 11 in the thickness direction, or as shown in fig. 7, the first protruding portion 23 is a protruding structure in which the surface of the first casing 20 extends toward the first peripheral edge 11 in the thickness direction. In contrast, the first recess 24 is a concave structure disposed on the heat exchange assembly and having a spatial dimension greater than that of the first protrusion 23. The second housing 30 is not shown in the drawings, it being understood that the arrangement of the second projections may be the same as or different from the arrangement of the first projections 23 described above. Preferably, the second protruding portion of the electric heating apparatus is a bent structure in which the second casing 30 is recessed toward the second peripheral edge 12 in the thickness direction, or a skirt structure in which the peripheral edge of the second casing 30 extends toward the second peripheral edge 12 in the thickness direction, or a protrusion structure in which the second protruding portion extends from the second casing 30 toward the first peripheral edge 11 in the thickness direction.
According to the electric heating device of the electric vehicle in the preferred embodiment of the present application, the first casing 20 and the second casing 30 of the electric heating device are respectively connected with the first periphery 11 and the second periphery 12 of the heat exchange assembly 10 by the adhesive sealant, and simultaneously, the adhesive sealant is fully and uniformly distributed in the adhesive sealant containing space 41 and the glue overflowing space 42 with a uniform spatial distance, so as to realize a uniform adhesive strength and a high sealing effect, and thus the control circuit board 16 and the resistance heating element 14 in the electric cavity 21 and the heating cavity 31 are protected from external water, moisture, dust and the like as much as possible.
The sealant needs to have better heat resistance due to the change of the working heat of the electric heating equipment, and under the optimal condition, the material of the sealant comprises at least one of silica gel mud, glass wool, silicon rubber, fumed silica, ferric oxide and hydroxyl silicone oil.

Wherein, when the pressure value in the electrical cavity 21 and/or the heating cavity 31 is smaller than the minimum value of the predetermined numerical range, the pressure balancing mechanism 17 allows external air to enter the electrical cavity 21 and/or the heating cavity 31; the pressure balancing mechanism 17 allows the gas in the electrical chamber 21 and/or the heating chamber 31 to be exhausted to the outside of the electric heating apparatus when the pressure value in the electrical chamber 21 and/or the heating chamber 31 is larger than the maximum value of the predetermined numerical range.
Preferably, the pressure balancing mechanism 17 according to the above embodiment may be further configured to ventilate the electrical cavity and/or the heating cavity and the external environment of the electric heating apparatus when the pressure in the electrical cavity 21 and/or the heating cavity 31 is different from the atmospheric pressure outside the electric heating apparatus, so as to keep the air pressure in the electrical cavity 21 and/or the heating cavity 31 substantially consistent with the external air pressure, thereby preventing the sealant from being damaged due to the pressure difference between the inside and the outside of the electric heating apparatus.
The pressure balancing mechanism 17 may be a vent valve controlled by a sensor for measuring the pressure of the gas, or the pressure balancing mechanism 17 may be an elastic material or an elastically openable and closable gas port provided with an elastic member, when the difference between the external pressure and the internal pressure of the electric heating apparatus is large, the gas on the side with the larger gas pressure enters or exits the electric cavity 21 and/or the heating cavity 31 by overcoming the elastic force of the pressure balancing mechanism 17. The pressure balancing mechanism 17 may also be provided with a filtering device (such as a filter screen, filter cotton, etc.) for filtering impurities such as dust particles or water vapor in the gas passing through the pressure balancing mechanism 17.
