Description

Technical Field

[0001] The present application relates to the technical field of radiators, and in particular, to a radiator with variable pitch and a vehicle. Background Art

[0002] When the radiator is working, the temperature of the cooling fins near the water inlet is relatively high, so more heat needs to be taken away by the cold air blown out by the fan. The temperature of the cooling pipes and cooling fins near the water outlet is relatively low, so less heat needs to be taken away by the cold air blown out by the fan. However, in the existing radiators, the specifications of the cooling fins near the water inlet and the cooling fins near the water outlet are the same.

[0003] Since the wind force of the cold air blown out by the fan weakens when it reaches the cooling fins near the water outlet, and the specifications of the cooling fins at each position are the same, the wind resistance of the cooling fins near the water outlet is relatively large, which further forms eddy currents and affects the heat dissipation of the cold air blown out by the fan. Summary of the Utility Model

[0004] In view of this, the purpose of the present application is to provide a radiator with variable pitch and a vehicle, so as to solve the problem that eddy currents are easily formed in the existing radiator, which affects the heat dissipation of the cold air blown out by the fan.

[0005] According to the first aspect of the present utility model, a radiator with variable pitch is provided, wherein the radiator with variable pitch includes: a housing; a core assembly disposed inside the housing, the core assembly being provided with a first pitch portion and a second pitch portion, the pitch of the second pitch portion being greater than the pitch of the first pitch portion; and a wind deflector disposed on the side of the housing, the wind deflector being provided with an air inlet, and the air inlet being directly opposite to the first pitch portion of the core assembly.

[0009] Preferably, the wave pitches of the first wave pitch segments of the plurality of heat dissipation belts are equal, and the wave pitches of the second wave pitch segments of the plurality of heat dissipation belts are equal.

[0010] Preferably, the length of the first wave pitch segment is greater than the length of the second wave pitch segment.

[0011] Preferably, the core assembly is formed into a plate-like structure, and the air shroud is arranged at the side of the housing facing the plate surface of the core assembly.

[0012] Preferably, the air shroud is formed into a conical structure, and reinforcing ribs are arranged on the air shroud.

[0013] Preferably, the radiator with variable wave pitch further includes: an upper water chamber arranged at the first end of the housing, the upper water chamber is provided with a water inlet, the upper water chamber is communicated with the cooling pipe, and the first wave pitch portion is arranged close to the upper water chamber; and a lower water chamber arranged at the second end of the housing, the lower water chamber is provided with a water outlet, the upper water chamber is communicated with the cooling pipe, and the second wave pitch portion is arranged close to the lower water chamber.

The air shroud is arranged at the side of the housing. An air inlet is arranged on the air shroud, and the air inlet is directly opposite to the first wave pitch portion of the core assembly.

[0026] Throughout the specification, when an element (such as, a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0027] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0028] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms.

[0033] As Figures 1 to 5 shown, according to a first aspect of the present utility model, a radiator with variable pitch is provided, and the radiator with variable pitch includes a housing 3, a core assembly 1, and a wind shield 2.

[0034] In the following description, reference will be made to Figures 1 to 5 specifically describe the specific structures of the above components of the radiator with variable pitch and the connection relationships of the above components.

[0035] As Figures 1 to 5 shown, in the embodiment, the core assembly 1 can be disposed inside the housing 3. The core assembly 1 can be provided with a first pitch portion 100 and a second pitch portion 200, wherein the pitch at the second pitch portion 200 is greater than the pitch at the first pitch portion 100. The wind shield 2 can be disposed on the side of the housing 3. An air inlet 21 can be provided on the wind shield 2. Preferably, the air inlet 21 is directly opposite the first pitch portion 100 of the core assembly 1. With such a setting, the stronger part of the cold air blown in through the air inlet 21 can pass through the first pitch portion 100 with a larger air resistance to take away more heat, and the weaker part of the cold air passes through the second pitch portion 200 with a smaller air resistance to take away less heat, thereby avoiding the cold air being blocked by the core assembly 1 to form a vortex.

[0036] Preferably, as Figures 1 to 3As shown, in the embodiment, the core assembly 1 may include a main plate 11, a cooling pipe 12, a heat dissipation belt 13, and a support plate 14. Preferably, the core assembly 1 may be formed into a rectangular plate-like structure. The number of the main plates 11 may be two. The two main plates 11 may be respectively disposed at two ends in the length direction of the core assembly 1. The two main plates 11 are disposed opposite to each other. A plurality of cooling pipes 12 may be disposed between the two main plates 11. Preferably, two ends in the length direction of the cooling pipe 12 may be respectively fixed to the two main plates 11. A plurality of heat dissipation belts 13 may be disposed between the two main plates 11. The plurality of heat dissipation belts 13 may be alternately disposed with the plurality of cooling pipes 12, that is, one heat dissipation belt 13 is disposed between two adjacent cooling pipes 12, and one cooling pipe 12 is disposed between two adjacent heat dissipation belts 13. Two ends in the length direction of the heat dissipation belt 13 may be respectively fixed to the two main plates 11. The number of the support plates 14 may be two. The support plate 14 may be a strip-shaped plate member. The two support plates 14 may be respectively disposed at two ends in the width direction of the core assembly 1. Two ends in the length direction of the support plate 14 may be respectively fixed to the two main plates 11.

[0037] Preferably, as Figure 5 shown, in the embodiment, the heat dissipation belt 13 may be formed into a wavy shape to facilitate heat dissipation. The wave pitch may be the distance between two adjacent wave valleys of the heat dissipation belt 13. Preferably, the heat dissipation belt 13 may include a first wave pitch section 131 and a second wave pitch section 132, and the wave pitch of the second wave pitch section 132 is greater than that of the first wave pitch section 131. In addition, the length of the first wave pitch section 131 may be greater than that of the second wave pitch section 132.

[0038] Further, preferably, as Figures 1 to 5 shown, in the embodiment, the plurality of heat dissipation belts 13 are arranged in parallel and at intervals. The first wave pitch sections 131 of the plurality of heat dissipation belts 13 are arranged at intervals in the width direction of the core assembly 1 to form the first wave pitch portion 100. The lengths of the first wave pitch sections 131 of the plurality of heat dissipation belts 13 may be equal, so that the first wave pitch portion 100 formed by the plurality of first wave pitch sections 131 is relatively neat. The second wave pitch sections 132 of the plurality of heat dissipation belts 13 are arranged at intervals in the width direction of the core assembly 1 to form the second wave pitch portion 200. The lengths of the second wave pitch sections 132 of the plurality of heat dissipation belts 13 are equal, so that the second wave pitch portion 200 formed by the plurality of second wave pitch sections 132 is relatively neat.

[0039] More preferably, as Figures 3 to 5As shown, in the embodiment, the pitches of the first pitch segments 131 of the plurality of heat dissipation bands 13 may be equal. The pitches of the second pitch segments 132 of the plurality of heat dissipation bands 13 may be equal. The pitch of the first pitch segment 131 of the heat dissipation band 13 may be the first pitch 1310, and the pitch of the second pitch segment 132 of the heat dissipation band 13 may be the second pitch 1320. The second pitch 1320 is greater than the first pitch 1310, so that cold air can easily pass through the second pitch segment 132, and thus the second pitch portion 200 of the core assembly 1 is easily supplied with cold air.

[0040] In addition, preferably, as Figures 1 to 4 shown, in the embodiment, the air shroud 2 may be disposed on the side of the plate surface of the housing 3 facing the core assembly 1, that is, on the right side of the housing 3 as Figure 2 shown. The air shroud 2 may be formed into a conical structure, that is, as Figure 3 shown, the diameter of the air shroud 2 may gradually decrease in a direction away from the core assembly 1. An air inlet 21 may be provided at the end of the air shroud 2 with a smaller diameter. Preferably, the air inlet 21 may be a circular hole. In actual use, according to the actual conditions of the fan of the vehicle engine, the specific setting size and specific setting position of the air inlet 21 may be adaptively modified.

[0041] More preferably, as Figures 1 to 4 shown, in the embodiment, a protruding edge portion may be provided at the air inlet 21, and the protruding direction of the edge portion is parallel to the axis of the air inlet 21. In addition, reinforcing ribs 22 may be provided on the air shroud 2 to enhance the strength of the air shroud 2. The reinforcing ribs 22 may be provided on the outer surface of the air shroud 2. As Figure 1 shown in the embodiment of , the number of the reinforcing ribs 22 may be four. One ends of the four reinforcing ribs 22 may be connected to the edge portion, and the other ends of the four reinforcing ribs 22 may be respectively connected to the four corners of the housing 3.

[0042] Preferably, as Figures 1 to 4 shown, in the embodiment, the radiator with variable pitch further includes an upper water chamber 4 and a lower water chamber 5. Among them, the upper water chamber 4 may be disposed at the first end of the housing 3 (which may be the upper end as Figure 1 shown). The upper water chamber 4 may be provided with a water inlet 40 for flowing in antifreeze. The upper water chamber 4 communicates with the cooling tube 12. The first pitch portion 100 of the core assembly 1 may be disposed close to the upper water chamber 4. The lower water chamber 5 may be disposed at the second end of the housing 3 (which may be the lower end as Figure 1 shown). The lower water chamber 5 may be provided with a water outlet 50 for flowing out antifreeze. The lower water chamber 5 communicates with the cooling tube 12. The second pitch portion 200 of the core assembly 1 may be disposed close to the lower water chamber 5.

[0043] During use, the high-temperature and high-pressure antifreeze enters the upper water chamber 4 from the water inlet 40, and then flows into the cooling pipes 12. The cooling pipes 12 conduct heat to the heat dissipation fins 13. The cold air blown by the fan is blown in from the air inlet 21 of the air shroud 2 and blows towards the core assembly 1. When the cold air passes through the cooling pipes 12 and the heat dissipation fins 13 of the core assembly 1, it takes away the heat of the cooling pipes 12 and the heat dissipation fins 13. The antifreeze gradually changes from high temperature and high pressure to low temperature and low pressure, and then flows out from the water outlet 50 of the lower water chamber 5. Since the wind force of the cold air blown by the fan is relatively large at the upper part of the core assembly 1 opposite to the air inlet 21 of the air shroud 2 (i.e., at the first pitch portion 100), the pitch (i.e., the first pitch 1310) of the heat dissipation fins 13 provided here can be smaller to take away more heat. While the wind force at the lower part of the core assembly 1 close to the lower water chamber 5 (i.e., at the second pitch portion 200) is relatively small, so the pitch (i.e., the second pitch 1320) of the heat dissipation fins 13 provided here can be larger to facilitate the passage of the cold air and prevent the formation of eddy currents, which may affect the effect of the cold air taking away heat.

[0044] In addition, according to a second aspect of the present invention, a vehicle is provided, and the vehicle includes the radiator with variable pitch as described above. The vehicle has the same technical effects as the radiator with variable pitch, and details are not described herein again.

[0045] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions described in the foregoing embodiments, or can easily think of changes, or make equivalent replacements for some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
