A high-heat electric heater

Abstract

The invention discloses a high-heat electric heater. The high-heat electric heater comprises a shell and a radiator body arranged in the shell, wherein the radiator body comprises multiple radiation fins which are sequentially connected; each radiation fin comprises a first radiation single fin and a second radiation single fin which are buckled and connected together; an isolated electric heating flexible wire is arranged between each first radiation single fin and the corresponding second radiation single fin; a flexible wire passage which is matched with the arrangement track of the corresponding isolated electric heating flexible wire is arranged between each first radiation single fin and the corresponding second radiation single fin; and each isolated electric heating flexible wire is located in the corresponding flexible wire passage. Compared with the prior art, the high-heat electric heater has the following advantages: the temperature rise of an outer surface which can be in contact with a human body is prevented from exceeding the national standard of 85 K due to the arrangement of the shell, so that the human body is prevented from being scalded when being in contact with the high-heat electric heater; the isolated electric heating flexible wires in the radiation fins can realize long-time heating with a nominal power, so that the nominal power of the isolated electric heating flexible wires can be exerted to the greatest extent.

Description

technical field [0001] The invention relates to an electric heater, in particular to a high-heat electric heater. Background technique [0002] The current electric heaters are roughly divided into the following types: 1. Electric heating oil heaters are generally assembled from multiple heat sinks. At the same time, a cavity is formed in each heat sink, and the heat conduction oil is filled in it. The electric heating element is soaked in heat transfer oil, and the heat is transferred by heating the heat transfer oil. 2. PTC heater It uses the fan to agitate air to flow through the PTC heating element to force convection, which is the main heat exchange method. 3. Convection heater The upper part of the electric heater shell is the air outlet, and the lower part is the air inlet. After the power is turned on, the air around the electric heating tube is heated up and flows out from the air outlet, while the surrounding cold air enters from the air inlet. Supplement, so re...

Problems solved by technology

In order to ensure the implementation of the above industry standards, none of the existing electric heating oil heaters can achieve long-term heating at the nominal power, so that the heating elements in the electric heating oil heaters cannot exert their maximum heating effect all the time, and the heating elements cannot The nominal power is maximized, causing a waste of resources and increasing the consumption cost of consumers

[0007] Although the PTC heater can achieve long-term heating at the nominal power, its air supply area is limited, and the internal fan will generate certain noise. The indoor air is very dry during use, and the scope of application is small.

[0008] Although the convection heater can achieve long-term heating at the nominal power, its power is often small, and the speed of air convection is slow. The heating area is still small

[0009] Although the radiant heater can achieve long-term heating with the nominal power, its heating area is small, the indoor air is very dry during use, and there must be light when heating, so the scope of application is small

[0010] Although existing heaters with profile structures can achieve long-term heating with nominal power and have a large heating area, they are heavy and costly

[0011] At present, the electric heating oil heater has become the mainstream product in the heater industry because of its above-mentioned advantages, and is generally accepted by consumers. The pressure is high, so the electric heating oil heater has very high requirements on the sealing of the heat sink, and its welding process is very complicated; the electric heating oil heater meets the design standard that the outer surface temperature rise of the electric heater with a metal outer surface does not exceed 85K, and it is generally used The rear end of the electric heating oil heater is set on the back cover to avoid the temperature of the heat sink at the rear end being too high and scalding the human body; a fall switch is also required on the electric heating oil heater to prevent the electric heating element from burning dry and causing danger after it falls; the electric heating oil heater The above-mentioned specific structure has greatly increased its production cost
