Definitions

  • the present disclosure relates to a technical field of living appliances, in particular to an oil heater.
  • the current oil heater works by using an electric heating rod to heat the heat-transfer oil in the metal cavity, and then the heat-transfer oil with the high temperature transfers heat to the ambient air through the metal cavity and the fin on the cavity so as to achieve the user's purpose of heating.
  • the higher the temperatures of the metal cavity and the fin the better the heat dissipation to the ambient air.
  • the edge of the fin of the oil heater generally has a very thin air cavity, the air cavity is provided with through holes spaced apart from one another by a certain distance, and the air enters the air cavity through the through holes. Since the thermal conductivity of the air is much lower than that of the metal (usually, the stainless steel), the oil heater in the related art can achieve the purpose of insulating the extreme edge of the fin from a part of the heat. However, the oil heater cannot cool the edge of the fin adequately only by relying on the air insulation design in the air cavity, and thus the user is still in danger of burns while using the oil heater.
  • the present disclosure aims to solve one of the technical problems in the related art at least to some extent.
  • the present disclosure proposes an oil heater capable of increasing a heat dissipation area of an edge of a fin, increasing a flow intensity of air on an inner surface and an outer surface of the fin, lowering a temperature of the edge of the fin, enhancing a heat dissipation capability of the fin, and avoiding the risk that the user may be burned while using the oil heater.
  • the oil heater includes: two oil pipes arranged in an up and down direction and spaced apart from each other; and a plurality of fins, each fin having two ends disposed to the two oil pipes respectively, defining an oil passage therein communicated with the two oil pipes, and having an air cavity spaced apart from the oil passage in at least one side edge of the fin.
  • the air cavity has a top air outlet.
  • each of opposite side walls of the air cavity has an air inlet, and an air guiding plate is provided at the air inlet for guiding air into the air cavity.
  • the heat dissipation area of the edge of the fin is increased, the flow intensity of the air on the inner surface and the outer surface of the fin is improved, the temperature of the edge of the fin is reduced, the heat dissipation capability of the fin is strengthened, and the risk that the user may be burned while using the oil heater is avoided.
  • the oil heater further comprises a bimetallic temperature controller configured to detect a temperature of a heat-transfer oil, wherein when the temperature of the heat-transfer oil reaches a temperature set by a user, a power source is turned off.
  • a bimetallic temperature controller configured to detect a temperature of a heat-transfer oil, wherein when the temperature of the heat-transfer oil reaches a temperature set by a user, a power source is turned off.
  • each of the opposite side walls of the air cavity has a plurality of air inlets, and the plurality of air inlets are spaced apart from one another in the up and down direction.
  • each air guiding plate has a free end extending into the air cavity.
  • each air guiding plate has a free end located outside the air cavity.
  • each air guiding plate on one side wall of the air cavity has a free end extending into the air cavity, and each air guiding plate on the other side wall of the air cavity has a free end located outside the air cavity.
  • a part of the air guiding plate outside the air cavity has an extension length less than or equal to half of a distance between two adjacent air cavities.
  • the air guiding plates on the same side wall are arranged parallel to one another.
  • each air guiding plate has an included angle of 5-15 degrees with respect to a vertical plane.
  • the plurality of air inlets in one of the opposite side walls of the air cavity are arranged right opposite to the plurality of air inlets in the other one of the opposite side walls of the air cavity in one to one correspondence along the direction parallel to the length direction of the oil pipe.
  • the plurality of air inlets in one of the opposite side walls of the air cavity are staggered with the plurality of air inlets in the other one of the opposite side walls of the air cavity in the up and direction.
  • both side edges of each fin define the air cavity therein.
  • first and second are used herein for purposes of description and are not intended to indicate or imply relative importance or significance.
  • the feature defined with “first” and “second” may include at least one this feature explicitly or implicitly.
  • a plurality of' means at least two, such as two or three, unless specified otherwise.
  • the terms “mounted”, “connected”, “coupled”, “fixed” and variations thereof should be understood broadly, for example, it may be a fixed connection, a detachable connection or an integral formation; it may be a mechanical connection, or it may be an electrical connection or mean communicable with each other; it may be a direct connection or an indirect connection through an intermediate medium, and it may be an internal connection between two elements or an interaction of two elements, unless explicitly defined otherwise.
  • the specific meanings of the above terms in the present disclosure can be understood on a case-by-case basis.
  • FIG. 1 An oil heater 100 according to embodiments of the present disclosure will be described below with reference to Figs. 1 to 10 .
  • Arrows in Figs. 2 to 5 refer to a flow direction of cold air in an up and down direction.
  • the oil heater 100 includes two oil pipes 1 and a plurality of fins 2.
  • the two oil pipes 1 are arranged in the up and down direction and spaced apart from each other. Both ends of each fin 2 are disposed to the two oil pipes 1 respectively, and each fin 2 is provided with an oil passage (not illustrated) communicating with the two oil pipes 1, that is, the two oil pipes 1 communicate with each other through the oil passages 20 of the plurality of fins 2 to form an oil circulation circuit. At least one side edge of each fin 2 is provided with an air cavity 21 spaced apart from the oil passage, and the air cavity 21 has a top air outlet 210. In a direction parallel to a length direction of the oil pipe 1, each of opposite side walls of the air cavity 21 has an air inlet 211, and an air guiding plate 212 is provided at the air inlet 211 for guiding air into the air cavity 21.
  • the oil heater 100 further includes a heating rod disposed in the oil pipe 1 located below to heat a heat-transfer oil in the oil pipe 1.
  • the oil heater 100 is provided with a bimetallic temperature controller. When a temperature of the heat-transfer oil reaches a temperature set by a user, the bimetallic temperature controller will automatically turn off a power supply, thereby improving the safety and reliability of the oil heater 100.
  • the oil heater 100 When the oil heater 100 is powered on, the heat-transfer oil in the oil pipe 1 located below is heated by the heating rod, and then the heat-transfer oil having a high temperature rises to the oil pipe 1 located above through the oil passages in the plurality of fins 2, so as to produce an oil path circulation.
  • the oil heater 100 radiates the heat of the heat-transfer oil through peripheral wall surfaces of the two oil pipes 1 and fins 2, thereby heating a surrounding space environment, and the air-cooled heat-transfer oil is lowered to the oil pipe 1 located below to be heated by the heating rod again, so as to start a new circulation.
  • the cold air outside the oil heater 100 enters the air cavity 21 via the air guiding plate 212 at the air inlet 211 of the air cavity 21, and flows out through the top air outlet 210, that is, an air flow passage is produced in the air cavity 21 in the edge of the fin 2.
  • the heat in the edge of the fin 2 is dissipated, thereby lowering a temperature of the edge of the fin 2.
  • each of the opposite side walls of the air cavity 21 is provided with the air inlet 211, the air cavities 21 of adjacent two fins 2 on the same side are not in contact with each other, such that an air flow channel is formed between the adjacent two fins 2, thereby facilitating the cold air outside the oil heater 100 in a horizontal direction to enter a high-temperature zone between the adjacent fins 2 of the oil heater 100 corresponding to the oil passages through the air flow channel, and also to circulate and flow between the adjacent fins 2 to exchange heat.
  • the "high temperature zone” merely indicates a temperature of a region of the fin 2 where the oil passage is provided is higher than that of a region of the fin 2 where the air cavity 21 is provided, and does not refer to a specific temperature value. Since the oil heater 100 according to embodiments of the present disclosure is provided with the air cavity 21 in the edge of the fin 2, an air gap in the edge of the fin 2 of the oil heater 100 according to the embodiments of the present disclosure is expanded, as compared with the oil heater in the related art, such that a heat dissipation area of the edge of the fin 2 is increased, which is beneficial to the heat dissipation of the edge of the fin 2 and hence the temperature of the edge of the fin 2 is reduced.
  • the inventors have found through extensive experiments that, as illustrated in Fig. 10 , in the oil heater 100 of the present disclosure, the arrangement of the air inlet 211 where the air guiding plate 212 is provided facilitates lowering the temperature of the edge of the fin 2.
  • the temperature of the edge of the fin 2 of the oil heater 100 according to the present disclosure is reduced from an original over-standard temperature to a temperature in a range where safety requirements are met, the temperature drop thereof is up to 20%, and the overall heat dissipation power of the fin 2 is slightly increased by 1%.
  • the air cavity 21 having the air inlet 211 and the top air outlet 210 is provided in the edge of the fin 2 and the air guiding plate 212 is provided at the air inlet 211, the heat dissipation area of the edge of the fin 2 is increased, the flow intensity of air on the inner surface and the outer surface of the fin 2 is improved, and the temperature of the edge of the fin 2 is reduced, i.e. strengthening the heat dissipation capability of the fin 2, and avoiding the risk that the user may be burned while using the oil heater 100.
  • each of the opposite side walls of the air cavity 21 is provided with a plurality of air inlets 211 spaced apart from one another in the up and down direction. It can be seen that since the plurality of air inlets 211 are spaced apart from one another in the up and down direction, the air guiding plates 212 arranged at the plurality of air inlets 211 also are spaced apart from one another in the up and down direction, so that the air inlets 211 with a louver structure is formed in the same side wall of the air cavity 21.
  • the cold air outside the oil heater 100 enters the air cavity 21 through the plurality of air inlet 211 under the guiding of the air guiding plates 212, thereby increasing the flow of the external cold air into the air cavity 21, improving the flow intensity of the air on the inner surface of the fin 2 and also enhancing the cooling rate of the edge of the fin 2.
  • the plurality of air inlets 211 form the louver structure, which has a turbulence effect and allows the air to form turbulence at the air inlet 211, such that an air boundary layer at the air inlet 211 is destroyed, thus improving the air convection heat-exchange efficiency near the air inlet 211, enhancing the heat dissipation capacity of the fin 2, and also facilitating the cooling of the edge of the fin 2.
  • the air guiding plate 212 has a certain inclination in the up and down direction, the air guiding plate 212 also has a certain guiding effect on the cold air in the horizontal direction.

  • each air guiding plate 212 extends into the air cavity 21.
  • the air guiding plate 212 can have a guiding effect on the cold air outside the air cavity 21, and also can ensure that the user will not touch sharp edges and corners, thus avoiding the risk that the user may be scratched, and improving the safety and reliability of the oil heater 100.
  • each air guiding plate 212 is located outside the air cavity 21.
  • the guiding effect of the air guiding plate 212 on the external cold air can be further improved, and a flow area of the cold air in the air cavity 21 is ensured, thus avoiding a large resistance to the cold air flowing in the air cavity 21 due to a reduction of the flow area, and also improving the flow intensity of the air on the inner surface of the air cavity 21 so as to enhance the cooling rate of the edge of the fin 2.
  • the air guiding plate 212 has a most significant turbulence effect on the cold air at the air inlet 211, when a part of the air guiding plate 212 outside the air cavity 21 has an extension length less than or equal to half of a distance between two adjacent air cavities 21. Therefore, in some preferred examples of the disclosure, the extension length of the part of the air guiding plate 212 outside the air cavity 21 does not exceed half of the distance between the two adjacent air cavities 21.
  • each air guiding plate 212 on one side wall of the air cavity 21 extends into the air cavity 21, and the free end of each air guiding plate 212 on the other side wall of the air cavity 21 is located outside the air cavity 21.
