Fast heating electric heater

Abstract

The invention discloses a fast heating electric heater which comprises a heat dissipation body. The heat dissipation body comprises multiple cooling fins which are sequentially connected. Each cooling fin comprises a first single cooling piece and a second single cooling piece which are buckled and connected together, wherein an insulating electric heating flexible wire is arranged between the first single cooling piece and the second single cooling piece, a flexible wire channel coinciding with the insulating electric heating flexible wire in arrangement track is arranged between the first single cooling piece and the second single cooling piece, and heat insulation empty ribs and heat insulation holes are formed at the positions close to the edges of the cooling fins. Compared with the prior art, the fast heating electric heater has the following beneficial effects that the temperature rise of an outer surface which the human body can touch can be prevented from exceeding the 85 K, namely the national standard due to the arrangement of the heat insulation empty ribs and the heat insulation holes, and the human body can be prevented from being scalded when touching the outer surface; the insulating electric heating flexible wires in the cooling fins can be heated for a long time with the nominal power, and people do not need to worry about the too high temperature of the edges of the cooling fins; and the nominal power of the insulating electric heating flexible wires can be brought into perfect play.

Description

technical field [0001] The invention relates to an electric heater, in particular to a fast heating 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...

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 installed on the back cover to prevent the temperature of the heat sink at the rear end from being too high and scalding the human body; in order to prevent the temperature of the electric control components in the front cover of the electric heating oil heater from being too high, it will be installed between the front cover and the heat sink. Insulation layer; a fall switch needs to be set on the electric heating oil to prevent the electric heating element from burning dry and causing danger after it falls; the above-mentioned specific structure of the electric heating oil greatly increases its production cost
